MV 600 SS SP Vaporizer

Part (a) Positing for Vaporizer

The crane had assisted with the CO2 vaporizer positioning in CGRS as shown below but it failed to position it into the CGRS due to roof height issue. To amend the issue, by using the forklift, CGRS operator are able to move the vaporizer into the CGRS plant without exceeding the roof height limits. The position of the vaporizer are meant to be nearby to a drain so that droplets formed from the CO2 liquid can be conveniently drained.

Part (b) Ground Drilling for Vaporizer

To tighten the vaporizer onto the ground, our mainetance team do for drilling for each sides (total of 4 side) in order for the placement of bolts, nuts and washers. After the tightening, the water level balancing is off the aligment and after some obresvations, it is seen that the there is a gap between the vaporizor and the ground at two sides as shown below. To compensate for the differ in ground heights, our mainetance team put a shim beneath the vaporizer before putting the bolt. In the end, the water level balancing is shown with a normal reading.

Part (c) Railing for Vaporizer

The railing is installed at 3 sides of the vaporizer to prevent any collision onto the vaporizer from pallet or forklift.

Part (d) Vaporizer’s Fittings and costing

Justification:

Inlet connection:

SS)Shut-off valve:

Firstly, to turn on the gas flow of CO2 through the vaporizer during refilling operation. Secondly, to turn off the gas flow when changing pallet connection from depleted pallet to filled pallet, this is to ensure safety purpose by preventing the backflow of gas from the vaporizer.

2) Vent/Purge valve

First, to safety vent out all the remaining gas and liquid which remained inside the tubing during the time period between after switching off the gas flow and before changing the pallet connection. Second, to purge the residual moisture and contamination.

3) Relief/ Safety valve:

To prevent the vaporizer from being overpressurized.

Outlet connection:

SS)Temperature gauge (exist with vaporizer)

To monitor and ensure that all the CO2 are in gas phase by refering to the phase diagram of CO2 (Pressure-Temperature graph) as shown below.

2) Check valve

To prevent backflow of gas into the vaporizer at all times.

*The specification for all fittings and tubing is stated as below

The outlet connection doesn’t need a venting valve since the CGRS mixed gas refilling itself is provided with one as shown below.
