Manual Air Separation Unit

Positioning in the Plant :

The expanded air generated from the Expansion Engine & R1 Expansion valve enters Air Separation Unit. The rich liquid containing Oxygen & Nitrogen is separated out in various stages The rich Liquid collects in the lower column of Air Separation Unit 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 droping from 4.5 kg/cm² to 0.5kg/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.long the lower & upper column.
