Air Separation Plant

Air Separation Plant

Air Separation Plant technique is using air as raw materials, through gas expansion refrigeration process to liquefaction of atmospheric air, and separate oxygen, nitrogen and argon from air, and obtains oxygen, nitrogen, argon products from air.

Air Separation Plant (ASU) adopts molecular sieve air purification, booster turbine expander, medium pressure air cycle refrigeration, double rectification column, full liquid air separation. The control and interlock of complete set plant will be operation in DCS or PLC system, the process will follow the most advanced and common international regulation, and design module on the premise of stable running. The Air Separation Plant including: air filtration system, air compressor system, air pre-cooling system, molecular sieve purification system, double rectification column system, liquid products storage system(if liquid products), instrument control system, electric control system etc.
