Annex 3. Process brief description

Ø  KDN-600Y air separation plant adopts completely low pressure process as:

Ø    Raw air enters air filter for removal of dust and other mechanical impurity, then it goes to centrifugal air compressor to be compressed to about 1.1Mpa (indicated on pressure gauge). After that, it goes to precooling unit via oil filter and cooler to be cooled to 8℃,then goes to MS purification system for absorbing of moisture, CO2 and CnHm. 

  • After purified, a small part of air is used as bearing gas for gas bearing expansion turbine. Then it goes to the main heat exchanger via gas cooler after being boosted, which is sucked from the middle of heat exchanger to the turbine expansion for refrigeration. After that, it goes back to the heat exchanger from the bottom. It flows out the cold box after being reheated. The other part flows to main heat exchanger for cooling, which is scuked from the bottom of heat exchanger to the bottom of nitrogen column for rectification. After rectification, liquid air rich in oxygen at the bottom and liquid nitrogen on the top can be gained. Liquid air rich in oxygen is cooled by cooler as the cold source of evaporator. Air rich in oxygen in the condenser evaporator flows out of the cold box after being reheated by main heat exchanger, part of which will be the regenerative air of M.S. purifier, and others will be discharged. Liquid nitrogen will be delivered out as production
