Sanghi - Air Separation Plant by Cryo Corp

The rich liquid collects in the lower column of Air Separation Plant after coming from R1 expansion valve & expansion engine. The final separation of air takes place in the upper columns using expansion valves RL & PL with pressure dropping from 4.5 kg/cm² to 0.5 kg/cm² and the temperature to -175⁰C. The Nitrogen being more volatile separates out first & the Oxygen separated is stored in the condenser from where it is pumped by the Liquid Oxygen Pump into cylinders.
