Description:


This plant adopts a MS purification air process with high temperature/low temperature booster expander, refrigeration by nitrogen recycle, as well as production argon by complete rectification without nitrogen.

  1. Feed air gets elimination of dust and other mechanical impurities in self-cleaning type filter and enters centrifugal compressor to be compressed to 0.62MPa(A), and then it’s cooled to 10℃ in pre-cooler. After air is elimination of CO2 and moisture in molecular sieve purifier, the purified air enters cold box and after it gets cooled by the reflux gas in medium pressure heat exchanger, it goes into lower column to be separated originally to obtain liquid nitrogen and enrich oxygen liquid air. Liquid air and liquid nitrogen are drawn from lower column to be cooled in subcooler, then the throttled air is fed into upper column to be further rectification. The product liquid oxygen is obtained at the bottom of upper column, and after subcooled in subcooler, it is fed out of cold box to liquid oxygen storage tank.
  2. After the waste nitrogen gas drawn from upper column is rewarmed and fed out of cold box for the regeneration gas of molecular sieve. Low pressure nitrogen gas is fed out of the top of upper column for supply client after it is compressed.
  3. The nitrogen gas at the top of lower column is divided into two streams. One is liquefied by liquid oxygen at low pressure side of main condenser and refluxed into lower column as the reflux liquid. Another stream is rewarmed and fed out of cold box, and then it enters medium pressure recycle nitrogen gas pipe.
  4. The medium recycle nitrogen gas is fed into recycle nitrogen compressor by nitrogen pipe, after the nitrogen gets compressed to 2.6 MPa(G), it is divided into two stream, after the first stream enters cold box to be cooled in medium pressure heat exchanger, it enters high temperature expander. The expanded nitrogen enters medium pressure heat exchanger to be rewarmed and fed out of cold box to pressure nitrogen main pipe. After the second one is boosted at boosting end of low temperature expander, it goes into cold box and after it is cooled in medium pressure heat exchanger, it is divided into two parts. The most expanded nitrogen in low temperature expander is rewarmed and fed out of cold box into pressure nitrogen main pipe. While the rest nitrogen cooled in medium pressure heat exchanger is throttled, one part of product liquid nitrogen drawn to be subcooled in subcooler and fed out of cold box into liquid nitrogen storage tank. The rest returns lower column as the reflux liquid of lower column.
  5. The nitrogen into pressure main pipe is compressed in recycle nitrogen compressor. A finished recycle supplies the refrigerant to the whole plant.
  6. A certain content argon fraction drawn from the middle portion of upper column is fed into crude argon column. The crude argon column is divided into two sections structurally. The reflux liquid in the bottom of the second argon column is fed into the top of the first section as reflux liquid through liquid pump. Crude argon obtained by rectification in crude argon column is fed into the middle portion of pure argon column. After rectification in pure argon column, the pure liquid argon obtained from the bottom of pure argon column is fed out of cold box and into storage tank.

A certain content of oxygen fraction drawn from the middle portion of crude argon column is fed into the top of high pure oxygen column as reflux liquid. Liquid oxygen at the bottom of column is vaporized and rectified with reflux liquid. And the high pure liquid oxygen obtained at the middle portion of high pure oxygen column as the product is fed out of cold box; the oxygen gas in the top is fed into crude argon column. A part of liquid oxygen drawn from bottom is fed into upper column.
