Both Nitrogen and Oxygen are removed through separate paths in Heat Exchangers, for cooling the incoming air,Oxygen is compressed to a prescribed settled pressure by a liquid pump and is directly filled into cylinders. Nitrogen is however available at a pressure of approximately O.5kgcm2 and the same can be compressed into cylinders with help of an independent high- pressure compressor.
