    Annex.3 . process

    Type KDON-550/1000 Air separation plant adopts full low pressure flow, the technology process:

    Raw air from atmosphere enters air filter for removal of dust and other mechanical impurity and goes to non-lub air compressor. After two stage compression to approx 0.65MPa(G) it goes to precooling unit to be cooled to 5~10℃,then goes to switch over MS purification system for absorbing of moisture, CO2 and CnHm. MS absorber purifier consists of MS vessels . While one MS absorber is working, the other is regenerated by waste nitrogen via heater to regenerate the MS.

    After purified, a small part of air is used as bearing gas for gas bearing expansion turbine. The rest enters cold box in which it is cooled in main heat exchanger by reflux(pure oxygen, pure nitrogen, waste nitrogen, etc. ) . Part of air is sucked from the middle of main heat exchanger to expansion turbine. Most of it after expansion via sub-cooler after cooled by oxygen in upper column is delivered to upper column. Small part goes to waste nitrogen channel via reheated out of the cold box. The rest continues to be cooled down in main heat exchanger to near liquefied air tempt. to lower column.

    In lower column , air is preliminary separated to nitrogen and oxygen enriched air. In condenser-evaporator, nitrogen is condensed while liquid oxygen is evaporated at the lower pressure side. Part of liquid nitrogen is used as reflux for lower column while the other part is abstracted from top of lower column via liquid air, liquid nitrogen sub-cooler is subcooled by pure nitrogen an waste nitrogen and throttled to be delivered to middle part of upper column as reflux.

    Product oxygen is abstracted from lower part of upper column and is delivered out of the cold box via expanded air sub-cooler, main heat exchanger to be reheated. Part is used as regenerated gas for MS purifier. Pure nitrogen is abstracted from top of upper column. Via liquid air liquid nitrogen sub-cooler and main heat exchanger it is reheated and delivered out of cold box.

    Oxygen from distillation column is compressed by O2 compressors to regulated pressure to customer.
