Annex 3. Process brief description
  1. Raw air enters air filter for removal of dust and other mechanical impurity, then it goes to muzzle screw air compressor to be compressed to about 1.3Mpa (indicated on pressure gauge). After that, it goes to , precooling unit via oil filter and cooler to be cooled to  510,then goes to MS purification system for absorbing of moisture, CO2 and CnHm.  MS absorber purifier consists of 2 vessels . While one MS absorber is working, the other is regenerated by waste nitrogen via heater to regenerate the M.S.
  2.    After purified, a small part of air is used as bearing gas for gas bearing expansion turbine. The rest is divided into 2 parts. One part enters cold box in which it is cooled in main heat exchanger by reflux(expanded waste nitrogen ). The other flows into vaporazing heat exchanger of high pressure liquid oxygen in the the cold box, which is cooled by liquid oxygen. Then they joints together in the middle of main heat exchanger, after being cooled again, it enters the air side of main heat exchanger in the column with rated moisture. Air is scuked after being liquified from main cooler and goes to top of column via sbcooler as relux.
  3. Liquid oxygen is sucked form mian cooler and goes to high pressure oxygen heat exchanger after being boosted by lox pump. Then liquid oxygen is heated by air to be delivered out of column as production.
  4. Compressed waste nitrogen is suncked from top of upper column and goes to the expansion turbine. The expanded waste nitrogen is heated in the main heat exchanger, then flows to M.S. purifier as regenerative air.
  5. For safety, please drain part of liquid air out of column to avoid accumulation of hydrocarbon, especially C2H2.
