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 bearin
