Position: Developer Engineer From: December 1998 To: January 2001

Company: Eficar Electronica, C.A.

City: Valencia State: Carabobo Country: Venezuela

Brief description of Eficar Electronic company.

Eficar Electronic Company was dedicated to manufacture ultrasonic

automotive injector cleaner machines with bench test. It was looking to expand

products in automotive area. In 1998, the company decided to manufacture new

equipment: an automotive gas analyzer.

Project: Design of automotive gas analyzer to 4 gases (CO, CO2, HC & O2).

Company: Eficar Electronic Starting: December 1998 Finishing: January 2000

My project of grade was to create the software to operate an automotive gas

analyzer of 4 gases: Carbon Monoxide (CO), Dioxide Carbon (CO2), Hydrocarbon

(HC- Propane or Hexane) and Oxygen (O2). This project was supported by the

company Eficar Electronica, C.A. which contracted me during my internship.

Immediately to get my degree like electrical engineer, the company Eficar

Electronica, C.A. hired me to give continuity to this project.

This project of degree consisted of a software developed in the

programming language Delphi 3. Delphi was a language programming developed

by the Borland Company and basically, it was the programming language Turbo

Pascal under Windows® operative system. This software was a direct competitor

of Visual Basic of Microsoft. Later, Microsoft bought Borland to finish Delphi in

2010.

The software developed with Delphi to control from host system to the

automotive gas analyzer made references to Application Program Interface (API)

of Windows to control the serial port of the computer.

4

The gas analyzer sensors were bought and imported from the company

Andros, Inc. in California State in USA. Andros was bought by LumaSense

Technologies inc. (www.lumasenseinc.com). The sensor to CO and CO2 use the

technology Non- Dispersive Infrared (NDIR) and the O2 sensor use the technology

electrochemical. The electrochemical O2 sensor and the NDIR sent the information

of measurement in an analogue value (0 to 5 V dc). The data adquisition and

conversion analogue to digital was made through an electronic card controlled with

a microcontroller brand Microchip model PIC 16F628A with 4 analog to digital

converters, USART module to implement RS232 asynchronous communication

and high current for direct LED drive. This microcontroller was programmed using

Language C and directives of assembler language MPASM of Microchip. The

microcontroller was programmed with a commands set to control 3 solenoid

valves, get information of the measurements and status of the sensors.

Figure 1. Automotive Gas Analyzer.

The host computer got the information of the sensors communicating with

the electronic card through RS-232 asynchronous protocol, with 8 bits of data, one

bit of parity, one bit of stop and 19200 bps.

5

The software shows in display the value of measurement of CO, CO2, HC &

O2 in 3 different ways: Numeric value in a table updated each second, a bar graph

and a XY graph (value vs. time). With 4 scales: 0 to 1 %, 0 to 25 %, 0 to 50 % and

0 to 100 %. It have been programmed with alarms letting to the operator chooses

the value to trigger the alarm. The default values are: 11% to CO2, if the smoke of

the car is lower than 11% means an incomplete combustion. 2% to CO, if the

smoke of the car is higher to 2% means an incomplete combustion and a lot of

contaminant gas. 1% to O2, if the smoke of the cars is higher to 1% means a

diluted blend of gas.

The application of this gas analyzer was not only to automotive area, it had

industrial application measuring the efficiency of combustion in burners, furnace

and boilers.

The advantage in automotive application was the portable of the gas

analyzer, because his supply was 12 V dc (9 to 16 V dc). It could be supplied by a

car battery. Other industrial gas analyzers are designed to be installed in a cabinet

or wall mounted, but the maintenance time is longer than the portable gas

analyzer.

The pneumatic system of automotive gas analyzer required one small pump

of flow 1 liters / min. with a filter system to remove the stream of the gas an excess

of particle of automotive smoke. The pump was activated by the same

microcontroller that manages the communication with the host computer. The

software in the host computer had programmed the process of calibration of the

sensors. The operator of the analyzer could buy a kit of calibration, which

consisted of one container with a blend of gases to 1200 psig of CO2 to 12 % v/v ±

1%, CO to 2% v/v ± 1%, HC as Propane 1200 ppm ± 1%, balance Nitrogen, a

flow meter type rotameter with range of 0 to 1 liter / minutes, a manual needle

valve, a container valve and a manifold of pressure of two steps with his respective

manometers and valves to each step. The software indicated to the operator when

open the valve of the gas container to one determined pressure and flow that the

operator controlled manually with the manifold´s valves and needle valve. The

software made a purge to ensure that only the patron gas was in the system and

6

after 30 seconds indicated to the sensor the value of gas that it was flowing. The

operator entered through the keyboard the value of label to CO2, CO and HC -

propane. In accord to the values showed in the gas patron´s certificated with

traceability and uncertainty emitted by the supplier of gas patron.

The O2 sensor was calibrated with clean air ambient. Considering clean air

the value of O2 % v/v in air ambient is 20.8%. The O2 sensor was calibrated each

time that the unit was turned on or come of sleep mode.

The software to operate the gas analyzer has two modes of operations: free

test where the unit get measurements of the sample gas each second during 5

minutes and a formal test where the unit gets measurements in accord to a

protocol applied to measure the automotive smoke powered by internal combustion

engines.

I wrote the operator and maintenance manuals of the automotive gas

analyzer.

Project: Design of a memory and control electronic card to injector cleaner machine.

Company: Eficar Electronic Starting: February 2000 Finishing: June 2000

Between the activities were: Modification of electronic memory card of a

ultrasonic injector cleaner machine with bench test, it was designed by engineers

of Eficar Electronica with technology of 10 years ago. My task consisted in

substitute the memory stage designed with 88 diodes (It was a design from 1978)

by a microcontroller brand Microchip, Model PIC16F84A. This microcontroller not

only substituted the memory stage, the control of the power transistors and control

of the led indicators in display were controlled by this.

I make the draw of the electronic card using the OrCAD software. It was the

first electronic card double layer made by Eficar Electronic.

Figure 2. Old & New model ultrasonic injector cleaner machine.

Project: Design of ultrasonic electronic card to injector cleaner machine.

Company: Eficar Electronic Starting: July 2000 Finishing: January 2001

Another important project was substituted the exciter circuit of ultrasonic

bath. Eficar was changing the supplier of ultrasonic transducer that go bonded in

the bottom of the ultrasonic bath and generate the ultrasonic waves that clean the

metals inside of the liquid deposited in the ultrasonic bath. The old transducer was

circular shape and the new transducer was ring shape. This last design used two

crystal bolted to a buffer of aluminum bonded in the bottom of the ultrasonic bath.

All the set gave is called ultrasonic of canyon knew by higher efficiency. Each

exciter electronic card matches with each ultrasonic canyon and it must be

adjusted and tested in factory before sell it.

Figure 3. Old & New model of Transducer in injector cleaner machine.

Considering that the automotive gas analyzer was a mature equipment to

sell it, Eficar Electronica closed the project as develop and it passed to production.

One of the owner of Eficar decided open another company called TECNOSECA. I

finished my relation of work with Eficar and I was hired by TECNOSECA.

Position:Project´s Engineer From: February 2001 To: January 2004

Company: Tecnología, Servicios y Equipos, C.A. (TECNOSECA)

Technology, Services & Equipments Co.

City: Valencia State: Carabobo Country: Venezuela

Brief description of TECNOSECA company.

Tecnoseca was a company of created to give solutions to requirements of

automotive equipments to Venezuelan market. Centering his business in emissions

control and automotive diagnostic.

Project: Design of equipment analyzer of opacity in exhaust smoke (Opacimeter).

Company: Tecnoseca Starting: February 2001 Finishing: July 2001

Working in TECNOSECA, I developed the new project of the Opacimeter or

equipment to measure the opacity of exhaust smoke of trucks powered with Diesel

engines or external combustion engines. Similar to automotive gas analyzer this

unit takes a sample of partial flow of exhaust smoke of a truck through a stainless

steel probe and a hose system. Carrying the smoke to unit detector where the

sample gas pass through a tube with a LED in an end and a detector of light in the

other end. If the light reaches the detector without attenuation is considered that

the opacity of sample gas is 0%. If the light doesn´t reach the detector is

considered 100 % of opacity of the sample gas.

The standard COVENIN 2903 requires a test that during 5 seconds with the

Diesel engine to maximum acceleration, it emits a peak of pollution and after 20

seconds of engine in idle, it is repeated the acceleration during 5 seconds. This

process is repeated 4 times, getting 4 peaks of maximum pollution or opacity.

Considering that 0 % is clear or transparent smoke and 100% of opacity is black

smoke. The limits of maximum values in accord to the manufacture year to trucks

in Venezuela is published in the official journal dated 19th August 1998, Act # 2673.

10

The software of the opacimeter guides to the operator such as the standard

requires, reducing the probabilities to make a mistake. The software decides if the

test is valid. Not there must be more than 10% of difference between the 4 peaks

of opacity, if not the test is invalid.

Project: Dealer of Automotive Scanner (Oscilloscope 4 channel, Multimeter, simulator of electrical signals & data trouble coder).

Company: Tecnoseca Starting: August 2001 Finishing: January 2004

During the Auto show PAACE Automechanika 2001, Tecnoseca sent me to

train with the company Andros, Inc. in Mexico City to know about a new model of

gas analyzer, a micro bench more compact. Andros, Inc. had his headquarter in

California, USA and they were doing training to his customers of Mexico. Visiting

the car show I was in contact with potentials dealers of our ultrasonic injector

cleaner machines and I was in contact with a manufacturer of automotive scanners

made in South Korea. That year, Tecnoseca became in an official dealer of

Hanatech, Ltd. Company of South Korea manufacturer of automotive electronic

diagnostic equipments.

The scanner ULTRASCAN were a equipment 4 in 1:

1. Data Trouble Code (DTC) reader.

2. Automotive Multi-meter.

3. Automotive Oscilloscope, 4 channels.

4. Simulator of signals.

The DTC reader had the biggest cover of brands of cars from America, Europe,

Asia and Oceanic assembler of cars with a suitcase of connector and adapters to

connect to almost every cars around the world.

The automotive multi-meter had very high impedance that avoid to flow of

current through the leads of multi-meter. In this way, it doesn´t interfere with the

measurement or in the electrical circuit.

The automotive oscilloscope 4 channels could be used in cars with or without

distributor (DIS). It came with a database of graphics of wave forms of injectors,

spark plug, throttle position sensor, camshaft position sensor, crankshaft position

sensor, knock sensor, mass air flow sensor, manifold air pressure sensor.

12

The fourth function of ULTRASCAN was a simulator of electrical signals. It

could simulate signals of wheel sensors, throttle position sensor, frequency signals,

voltage of 0 to 5 V dc of amplitude.

The ULTRASCAN was a complete equipment to test the electronic of a car. I

translate the manual from English to Spanish language and the training of use of

this equipment was to my charge in Venezuela.

Project: Participation in Comité Venezolano de Normas Industriales (COVENIN) or Committee Venezuelan of Industrial Standards to upgrade the standards 2168, 2227 & 2903.

Company: Tecnoseca Starting: September 2001 Finishing: September 2002

In 2001 year and during a year, I participated in the modification and

upgrade of a national standard to verify the automotive emissions in Venezuela.

The group of companies and institutions of the government invite us to participate

in meetings about the new standard. This committee had a meeting each two

weeks in the capital of the republic (Caracas city) in the headquarter of

Fondonorma, Fondo para la Normalización y certificación de la calidad ( Fund to

standardization and quality certification), the most important institution of

standardization of Venezuela. The committee was identified as CT 44

Enviromental Quality. Sub Committee technical CT44/SC2 Air Quality. This

committee was integrated by all the companies and institutions involved in the

theme of automotive emissions like: Ministry of environment, PDVSA (Oil & gas

statal company), FORD of Venezuela, GM Venezuelan, TOYOTA of Venezuela,

Chrysler, Mack, Volvo, Fiat trucks, Drivers public association, National Institute of

technical schools, seller of gas analyzers.

We redacted the standards

COVENIN 2168-2002 Calidad de aire. Instrumentos para la medición de

emisiones de escape de los vehículos (Air Quality. Instruments to

measurement of automotive exhaust emissions).

COVENIN 2227-2002 Calidad de Aire. Medición de emisiones de monóxido

de carbono, Dióxido de carbono, Oxigeno e Hidrocarburos provenientes del

escape de fuentes móviles en condiciones de velocidad mínima ( Air

Quality. Measurement of emissions of Carbon Monoxide, Carbo Dioxide,

Oxygen and Hydrocarbons from exhaust of sources mobile in idle

conditions.

COVENIN 2903-2002 Calidad de Aire. Determinación de la opacidad del

humo en el escape de vehículos con motores Diesel. (Air Quality.

Determination of smoke opacity in exhaust of vehicles with Diesel engines).

A highlight was that I could include an image of our opacimeter as a reference

in the appendix A of the standard COVENIN 2903.

Figure 6. Requisition of observation to standard 2903 and Annex A.

15

Project: Transaction of Model approval Certified to Gas Analyzer and Opacimeter.

Company: Tecnoseca Starting: December 2002 Finishing: June 2003

Knowing very well the national standards, I adapted the software of the gas

analyzer and opacimeter in accord to COVENIN standards.

I exposed the units opacimeter and automotive gas analyzer in front of

SENCAMER (autonomous national service of standardization, quality, metrology

and technical regulations) to be evaluated under the new standards. During a year

the units were evaluated with several patron gas, cross-checking with other units to

corroborate accuracy, repeatability, precision. With this activity the units received a

certificate that approved the model to be used in the country.

Project:Design of Data Acquisition Equipment to GM Venezuelan.

Company: Tecnoseca Starting: January 2003 Finishing: March 2003

Selling gas analyzers to GM Venezuelan, we got the opportunity of work

under contract in the product engineering laboratory´s GM. The laboratory tested

the car´s parts manufactured in Venezuela, like automotive battery, brake pads,

compressor and evaporator from air conditioning system, radiator and thermostat

valve from cooling system, alternator and regulator of voltage from electrical

system. The test laboratory´s GM required a data acquisition equipment to do the

test to each part made in Venezuela in a drive test outside of the GM factory. The

data acquisition unit was divide in 4 modules. Two modules of thermocouples, 24

type T and 4 type K. Another module to measure RPM engine, noise through a

decibel meter, anemometer, stress in brake pedal, hygrometer, fifth wheel, vacuum

and voltage (0 to 16 Vdc) and the last module where was the data acquisition and

communication electronic cards. This module was connected to a laptop through

parallel port, where run software called Visual Designer 4.0 made by Intelligent

Instrumentation,Inc. Visual Designer 4.0 was a programming language type block

graphic Windows-based application.

Project:

Re-Designed of Automotive Gas Analyzer to Mexico standards.

Company: Tecnoseca Starting: March 2003 Finishing: August 2003

The dealer of the Ultrasonic injector cleaner machine in Mexico was

interested in sell automotive gas analyzer to his government. Mexico city have a

population of 30 million of people and is a city very contaminated by automotive

pollution. Our dealer in Mexico sold gas analyzer from an Italian manufacturer but it

was an equipment stand alone, a reader of 4 gases (CO, CO2, HC & O2) that

showed the measurement in 7 segments displays. This model required

modifications to sell it in a program Inspection and Maintenance in Veracruz

province. The manufacturer of Italian gas analyzer required the buy of 100 units to

made the changes in his equipment and connect to a host computer with two

printers, such as the sub secretary of environment of Veracruz province required.

We only required to buy 15 units to make the changes to our software and

hardware because the requirements of the Norma Oficial Mexicana NOM (Official

Standard Mexican) required the design of a new unit.

The automotive gas analyzer to Mexican market was designed with a

desktop personal computer with operative system MS- Windows. The PC was

stayed in a cabinet with roller to easy move with two printer, one to print the

original certificate in sealed paper with triple copy: customer, government and

owner of verification center. Another printer with standard white paper to print a

result if the car not approved the test. The cabinet had 3 doors, one to each printer

and another to access to the PC and gas analyzer in case of maintenance or audit.

Each one of 3 doors had a limit switch indicating if the door was opened or closed.

This information with the time and date were saved in a log file to each door. The

government required that this log file registered the information with or without grid.

In the case of a blackout and somebody opened any door, the equipment shall

registered the date and time and what door was opened or closed. This last

requirement complicated the design because we required using a micro PLC.

Model LOGO! 230 RCo without display with a communication module ASi and a

Uninterrupted Power System UPS, all devices brand Siemens. Doing use of the

18

EPROM of the PLC was registered the time & date that the 3 doors were opening

and closing. In this way, it guaranteed the register of activity of 3 doors during 24

hours. Eventually, the PLC synchronized and updated the log file with the PC.

I delivered the draws and the design of the cabinet to the dealer with the

purpouse that they manufacture the cabinet in Mexico and we sent the unit gas

analyzer in a small package from Venezuela, reducing the shipping cost.

Project: Design of Data Acquisition Equipment to FORD of Venezuela.

Company: Tecnoseca Starting: September 2003 Finishing: December 2003

In the same way, that we sold gas analyzer in Ford of Venezuela to the

laboratory test and line assembly of cars, I worked in a project of manufacture a

data acquisition equipment of NVH (Noise, Vibration & Harnesses) of automotive

application under requirement of Ford. This unit was conformed by one

accelerometer of 2 axis, strain gage using a Wheaston´s bridge to take

measurements of deformations, 8 thermocouples type T.

Finishing 2003 year, Tecnoseca Company decided stop activities because

of a general national strike that it stayed during 3 months.

Position: Project´s Engineer From: February 2004 To: January 2015

Company: MASTERTECH, C.A.

City: Maracay State: Aragua Country: Venezuela

In February 2004, I founded a new company MASTERTECH, C.A. join other

business partners. It dedicated to develop projects of automation, instrumentation,

environmental and automotive projects. At this moment, the company is active.

Continue selling automotive gas analyzers, opacimeter, ultrasonic injector cleaner

machines, doing calibration & maintenance to old units.

20

Project: Design of a New Opacimeter Brand: Mastertech, Model: 2903.

Company: Mastertech, C.A. Starting: February 2004 Finishing: January 2005

The old supplier of opacimeters, Andros, Inc was bought by LumaSense

Technologies, Inc. and pulled out of production the old opacimeter. This situation

forced to look another supplier of opacimeter unit detector. The new supplier was

Sensors, Inc. With similar characteristics serial communication RS-232, power

source 110 V ac or 12 V dc. The software was developed using Visual Basic. In the

same way, the software guide to the operator under the rules of the standard

COVENIN 2903-2002.

This unit opacimeter has been sold to companies as Pepsi, Coca Cola,

Polar to do maintenance to their fleet of heavy duty vehicles and assure that they

exceed efficiency standards of emissions.

21

Project: Design of a New Automotive Gas Analyzer Brand: Mastertech, Model: 2168.

Company: Mastertech, C.A. Starting: January 2006 Finishing: February 2007

Using detectors of the new supplier (Sensors, Inc.), I proceed to develop a

new automotive gas analyzer. Sensors, Inc. developed a microbench to detect 5

gases with serial communication RS-232 and power source of 12 V dc. In the

same way that the new opacimeter, the new application of thee gas analyzer was

developed in Visual Basic.

it is a filial of PDVSA in charge of investigation and development of new

technologies to extract, exploration, production and refining of oil. The huge heavy

oil reserves compel to investigate the ways to obtain the best yield and benefit of

this tar.

INTEVEP is organized in several general managements. In particular, the

refining general management was where I worked, in two departments:

Product quality.

Pilot plants.

23

Product Quality Department.

It is in charge of do tests of quality to oil products, such as: Diesel, octane of

gasoline, jet fuel, fuel oil, greases and lubricants, asphalt, bio diesel, ethanol and

formulation of new fuels and lubricants. Product quality department is formed of 4

divisions: Lubricants, Fuels, Asphalt and Automotive. Automotive division was the

division where I worked.

The automotive area has the responsibility of do test to new formulations of

combustibles and lubricants on engines and vehicles.

After one and a half year and in a process of restructuring of staff of Intevep

by human resources department, I was moved from product quality department to

pilot plants department.

Pilot Plants Department.

It’s responsible of test, improve and optimize refining process. Formed with

38 plants, 27 of process and 11 of industrial services. Tank Farm with 11 tanks

equipped to handle light, medium and heavy crude, able of pumping through

mantled pipelines with controlled temperature to plants of process. The industrial

complex of Pilot Plants is formed by physical separations plants like: atmosphere

Project: Upgrading chassis dynamometer and Engine bench.

Company: PDVSA Starting: July 2004 Finishing: December 2005

The automotive area of Intevep has two dynamometric chassis where it can

mount a car over roller and apply forces and make a simulation of the car driving in

the street or in a highway.

The chassis dynamometric had singles gas analyzers of CO, CO2, HC

technology NDIR, Oxygen´s gas analyzer technology ionization of flame (FID).

NOx ´s gas analyzer of a very high precision. Every analyzer sent his value

measured to one PC. The software in the PC was developed with LabView 4.0 of

National Instruments, Inc. Because of incompatibility between the versions

LabView 4.0 and LabView 7.0 and the use of a new group of data acquisition

electronic cards. The laboratory required a migration from LabView 4 to 7 with the

exchange of data acquisition cards. The LabView software is a programming

graphical language, similar to Visual Designer that I used in the manufacture of the

data acquisition unit of GM. LabView let do activities of a Supervisory Control

Acquisition Data SCADA. National Instruments sells everything associated to

install a SCADA system in a PC.

Figure 12. Chassis dynamometer and engine bench facilities in INTEVEP.

25

The area has three bench to test engines, two Diesel engines (brands

Cummins & Detroit Diesel) and one gasoline engine (brand Toyota). The engine is

mounted over two columns and connected to cooling and supplier system. A

dynamometer type Eddy current motor is coupled to the engine to bring under

stress and make simulation of load to the engine.

I was in charge of install the new SCADA with LabView 7.0 in the two Diesel

engines including the instrumentation of the engine with thermocouples. And the

installation of the cooling water system to refresh the engines.

The laboratory has a dilution & sampling system, constant volume sampler

and a system of pressure and temperature controlled of the air intake for the

engines. All the system is brand HORIBA.

Working in the quality products department I published three technical report

and I was in participation in one congress.

Under the document number INT-10599, 2005 was published in Intevep the

results of a study on the effect of water microemulsion diesel fuel (second

generation) on the components of the injection system of a utility vehicle Chevrolet

Isuzu NPR 4HF1. I showed this work in the VII Congress Venezuelan of Chemical

made in University of Los Andes, Merida city in Venezuela.

The technical report, document number INT-10797, 2005 published in

Intevep shows the results of a study on the actual octane requirement Venezuelan

fleet and valve recession. This study was commissioned to explore the impact of

eliminating lead in gasoline and the incorporation of ethanol in gasoline engines of

automobiles in Venezuela.

The third document published was “Implementation of data acquisition

system for sampling the electrical signals from thermocouples installed on a brand

Detroit Diesel Series 50 engine using FieldPoint devices (controller and modules)

together with the LabVIEW graphical programming package” under document

Project: Maintenance of electric motors of exhaust fan system.

Company: PDVSA – Intevep. Starting: January 2006 Finishing: March 2006

The exhaust fan system of Pilot plants is a facility of vital importance to

operate the plants of the building HDT. Inside of this building there are 15 plants

and the exhaust gas system is a warranty to the operator of work in a clean

atmosphere free of heavy gases. The heavy gases are expelled from the building

through a set of 24 sewer. These gases are product of chemicals reactions in the

process, that by an operation fail go out to the environment then they are sucked

by the extraction system. H2S gases are very dangerous to the operator health.

I was in charge of team workers to extract the electrical motors from the

fossa, changing bearing, balancing blades, doing test of electrical isolation with a

megaohmeter to both motors.

Project: Installation of control system to carbon and sand filter.

Company: PDVSA Starting: November 2007 Finishing: January 2008

One of the goals of the management of pilot plants were get data online of

the industrial services plants like stream, demineralized water, cooling towers,

chemical additives, treatment water to boilers.

I changed the old carbon’s backwash system and sand filter tank. The old

system was a mechanical system without electronic nor communication. The new

systems was an electro hydraulic system with an electrical motor to move gears

and electronic communication card where it get status data of carbon and sand

filter.

I integrated this information of status to DCS of pilot plants.

Project: Installation and commissioning of FCC plant.

Company: PDVSA Starting: April 2006 Finishing: July 2008

In 2006, the management of pilot plants bought a new FCC pilot plant to

Zeton, Inc. (Burlington, ON, Canada) under license of Grace, Inc. (Columbia,

Mayland, USA) to substitute the old FCC pilot plant under license of Kellogg, Inc.

I was on charge of the FAT & SAT of the new FCC pilot plant in the area of

instrumentation and controls.

A teamwork in kinds areas received a training in operation of the FCC pilot

plant in facilities of Grace. And after of that we went to Zeton to do the FAT. Two

years later when the plant was installed in pilot plant of PDVSA we did the SAT.

Our training was in the software IFIX a SCADA of General Electric, Inc. and

several instruments like gas meter with water seal, gas analyzer of CO2,CO, NOx,

SO2,O2 and PLC C70, C50 & HC500 software of Honeywell.

Project: Installation of Hydrogen Plant, First stage.

Company: PDVSA Starting: June 2007 Finishing: November 2009

For several years the hydrogen plant consists of two set, it were working

with intermittent failures that allowed not operate them continuously, or reliability. In

the industrial complex of Pilot plants, there are 3 process plants that consume a lot

of quantity of hydrogen, with store capacity of 16 cubic meters of H2 and process

plants in operating, the autonomy reach to operate 48 hours.

With more than 30 years old and a revamp applied 10 years before. The

substitution of the plant was necessary. ABB didn’t have support to hydrogen plant

and scarce spare parts, the plant was obsolete.

I participate in choose between a matrix of 3 likely suppliers: Norsk Hydro in

Norway (www.hydro.com), Hydrogenics in Canada (www.hydrogenics.com) and

AccaGen in Switzerland (www.accagen.com) of one hydrogen generating plant of

40 NM3/h. After a process of technical and economical evaluation, Accagen was

selected to manufacture the set 1 of the hydrogen plant.

In February, year 2008 we make the Factory Acceptance Test (FAT) in

Lugano, Switzerland together Moody’s company (www.moodys.com), agency

international of risk qualification, contracted by PDVSA to do an assessment about

if Accagen had manufactured the hydrogen generator in accord to our

requirements.

Returning from Switzerland, began with the work of dismantling and storage

of the old station one hydrogen generating plant. We perform civil, mechanical and

electrical adjustments for the installation of the new hydrogen plant that was on the

way.

30

The control system current are based in PLC model: S7-300, brand

Siemens with touch screen Simatic, Industrial UPS Siemens, intrinsic barriers

brand Pepperl + Fuchs for meet the requirements of ATEX standards.

After the physical installation, we proceed with the protocol of SAT test, the

training of operators, training of maintenance team and evaluation of interlocks

physical and of software. The Project finished with a successful operation of the

plant.

Project: Participation in FAT of a pilot plant of nanoreactors catalytic.

Company: PDVSA Starting: July 2008 Finishing: February 2010

In August 2008, I was travelling to Burlington, Ontario, Canada by second

time to do a FAT to a pilot plant bought to Zeton, Inc. In this occasion it was a pilot

plant of nano reactors catalytic used to investigate new catalyzers to refine heavy

oil with hydrogen injection. This pilot plant is the same plant repeated three times.

i.e., three pilot plants identical each other. In the facilities of Zeton, Inc. we do a list

of task to check that the instruments, sensors, wired, controller, valves were

working in good conditions.

As the FCC pilot plant bought to Zeton earlier, the PLC installed to control

the process in each plant was a model C70 of Honeywell. And the PLC used to

control the safety system was a model C50 of Honeywell, too. With a SCADA

software IFIX of GE supervising and monitoring the PLC’s.

This is a good practice of Zeton with regards to use of controller, in the case

of small of medium size of plants, they install controllers C70 & C50 of Honeywell.

And in the case of plants of big size they install DSC Delta V of Emerson.

Project: Planning of shutdown FCC plant in “El Palito” refinery.

Company: PDVSA Starting: April 2010 Finishing: July 2010

The stripper tower of Fractional Cracking Catalyst (FCC) plant of “El Palito”

Refinery seated in Moron town, Carabobo province in Venezuela, required to be

exchanged by another bigger tower. Expanding the capacity of the plant to 30 %.

FCC process is the main process to get jet fuel, kerosene and gasoline for export

in this refinery.

I integrated the team to plan the shutdown of the FCC plant. Required to

uninstall the old stripper tower to install the new one. Feeding the Primavera

software to establish the time and lapses of each task of uninstallation of

instruments and wired of the old FCC tower.

Project: Planning of turnaround in upgrader plant “Petro-Piar”.

Company: PDVSA Starting: September 2011 Finishing: December 2011

The upgrader “Petro-Piar” is a join venture between Texaco and PDVSA. It

seated in the Caribbean seashore, near to Barcelona city, Anzoátegui province.

The plant receives diluted heavy oil from oil wells in Orinoco´s belt in front of

Orinoco river’s coast. The heavy oil received come with around 10 API degrees

and it is improved to 15 API degrees, obtaining a synthetic crude commercial.

Project: Automation Aquaconversion® Plant.

Company: PDVSA Starting: January 2009 Finishing: November 2014

This technology offers an alternative to transport, saving diluents, of heavy

and extra heavy oil from Orinoco’s belt. I received the training to install the

Distributed Control System (DCS) model System 302, created by Smar company. I

did the selection of flow mass transmitter (Coriolis technology) made by Endress &

Haussen, the differential pressure and pressure transmitters brand Smar. All of

these instruments with communication protocol Foundation Fieldbus. I worked in

selection and distribution of electrical conduits, pipes, terminal blocks, electrical

boxes to lead the electrical signals of thermocouples from reactors, heat

interchangers, tanks, pumps installed in a building of 3 floors to the control room

closed to the building. Defining dimensions, distribution of electrical load and

distribution in the space of the building. The selection of thermocouples type K was

in my charge, with details of dimensions, large, gross, mechanical connection,

electrical connection. It installed in reactors, heat interchangers and tanks. In

accord to the operations conditions (pressure, temperature, viscosity and pipe

diameter) indicated in Process Flow Diagram (PFD) elaborated by process

engineering team. I selected the manometers of the plant with seal to avoid direct

contact between the process and the bourbon tube. I considered choose the

manometers in three ranges applicable to different operating values with the

purpose of reduce the variety of manometer installed and spare parts and obtain

economical efficiency. Elaboration and modification of Piping & Instrumentation

Diagram (P&ID) based in ISA 5.1 standard.

Project: Installation of Radar Level Tank Measurement system.

Company: PDVSA Starting: August 2012 Finishing: May 2013

The pilot plants complex have a farm tank conformed by 13 cylindrical tanks.

Each tank has a blender and heater system fed with steam. The tanks are filled

with heavy, medium and light oil. Based on the experience of install a radar level

measurement system in big tanks, we proceed to install the same radar level

system in 8 tanks, brand Rosemount with a new model Raptor.

I configured each radar system taking in consideration sector covered by the

blades of the blender that move the product inside of the tank, sector of the heaters

that warm the product. In some cases two heaters was in transversal way to the

wall of the tank and in other case the heater were in parallel way to the walls of the

tank. All this information was necessary to fit the best place where install the

antenna of radar system.

I integrated the radar level system of farm tanks with the DCS system of

pilot plants.

Project: Upgrading of Power Sources of DCS of Pilot Plants Complex.

Company: PDVSA Starting: June 2013 Finishing: September 2013

The Distributed Control System (DCS) that operate the 14 plants automated

of Pilot Plants complex of PDVSA - Intevep was installed 20 years ago. Initially, it

was installed by ABB as Model INFI 90. It has been upgrade to the current

Symphony DCS of ABB by stages. The power sources haven´t been upgraded and

it was required by obsolescence.

Ten power sources redundant supply the voltage DC to the control cabinets

that host the electronic cards and the electrical load in DC of DCS. The power

source comes in several voltage levels: 24, 12, 5, 18, -18 V dc.

I coordinated the labors of a team of 3 electrical technologists to uninstall

the old sources and install the new sources.

Figure 21. Installation of power sources of DCS, brand ABB.

Project: Installation of Industrial Wi-Fi Network.

Company: PDVSA Starting: October 2013 Finishing: December 2013

Some of the plants of the pilot plants complex of PDVSA - Intevep are far

away of the building host of DCS. These plants are controlled by control systems

proprietary. Using different brands of control systems as Honeywell, Siemens,

Labview, Net-DAS without report data to DCS. When somebody wants to get data

of these plants were necessary go to the plant to collect the data.

In this project, my work was coordinate with teamwork, the activities to

install the infrastructure of antennas. Choosing the best place to install the

antenna. Connecting the antennas to the network ethernet and setting the

information in the DCS.

Project: Substitution of Fire & Gas System detection under SIS standards.

Company: PDVSA Starting: January 2014 Finishing: November 2014

Another important goal of the management of pilot plants was substitute the

old system of Fire & Gas detection because it was installed 20 years ago and it

wasn’t update to the new requirements of international standards IEC-61508, IEC-

61511, ISA S83-01-2004, NFPA72 and K-363 of PDVSA. Under a teamwork we

designed the new system of detection of fire and gas, installation of devices

(controllers, UV flame detectors, manual station, buzzers, etc.) and wiring of these.

I Integrated the F&G System with DCS, extinction system and emergency

shutdown (ESD). I drew plan, maintenance and operative manuals. Elaborating

operation’s philosophy and logic of programming. The ESD and F&G were

programmed in a PLC triple redundant branch Rockwell, model ICS- Triplex

following a previous work where was determined a SIL3 (Safety Integrity Level) in

the pilot plant. It was introduced a SIS (Safety Instrumented System) to reduce the

risk from SIL3 to a tolerable risk region. Working under the rules of the technical

report ISA TR.84.

Conclusion.

The information supplied in this document has the function of show to

APEGS staff the areas of electrical engineering in which I have worked.

Beginning in automotive emission area and passing to Oil & Gas area, I’ve

gained experience in application of electrical and electronics controls in

combustion process from levels of chemical reactions to levels of controlled

combustion in engines Otto and Diesel cycles.

Doing use of recent technologies in industrial instrumentation like

Foundation Fieldbus, Industrial Wi-Fi, Safety Instrumented Systems.

The advantage of work in Pilot Plants of refining of oil let me learn about a

variety chemical processes present in big refineries but in small size. To difference

between refineries, the pilot plants require changes constantly and assortment of

control systems of different brands like Honeywell, Allen & Bradley, Siemens, ABB,

Rosemount, Emerson, GE, National Instruments. And knowing of communication

protocols like OPC, RS-232, RS-485, Fieldbus, Modbus. Managing all class of

control systems like DCS, SCADA, PLC, PC and embedded microcontrollers.

Designing equipments of automotive emission controls let me stay in two

position like user or supplier, selling these equipments in several countries.

Supporting and understanding requirements of national standards in these

countries.

A total of three technical reports published in Intevep INT-10599, 2005; INT-

10797, 2005; INT-11048, 2006 and participation in committee technical CT44/SC2

to elaborate three national standards COVENIN 2168, 2227, 2903 – 2002. They

are the published documents of most significance.

I hope that this information can clarify my experience in electrical

engineering area.
