Description:
The KDON-5500/10000 Air Separation Plant employs a process that air is purified with molecular sieve at normal temperature, booster expansion turbine is used to produce refrigerating capacity, structural packing is applied and argon is extracted through full rectification.
The compressed purified air is divided into three streams: one stream is fed out to be instrument air; another stream is boosted through circulating compressor; the rest enters main heat exchanger to be cooled by reflux gas and then enters lower column.
Following preliminary rectification in lower column, the liquid air and pure liquid nitrogen are obtained from lower column, and liquid oxygen with purity of 99.6% is obtained from the bottom is fed to liquid oxygen pump, and then sent to the client after being rewarmed in main heat exchanger.
The pure nitrogen gas withdrawn from the top of upper column goes out of cold box to cooling water tower after being rewarmed in subcooler and main heat exchanger.
The waste nitrogen gas drawn from the upper portion of upper column after it is re-warmed in subcooler and main heat exchanger, it goes out of cold box to meet the need of regeneration gas of molecular sieve first, and the rest is sent to water cooling tower.
A certain amount of argon fraction withdrawn from the middle of upper column is fed to the crude argon column. The crude liquid argon is obtained through argon fraction rectificated in crude argon column and fed to the middle of pure argon column. The pure liquid argon is obtained at the bottom of pure argon column following rectification in this column.
