Description:


The proposed plant employs a double columns process in which air is purified by molecular sieve and refrigeration with drag flow expansion.

  • Following the preliminary process, the air is cooled to be reached saturated condition.
  • The air out of adsorber will be divided into three steams: one steam will be withdrawn as instrument air, the second steam goes into the main heat exchanger E1 directly to be cooled, and then part of it will reach saturation temperature after going out of E1, and then goes to the bottom of lower column C1 to follow the rectification; the third steam goes to the main heat exchanger after being boosted and cooled in theboosting end of expander , and then it is withdrawn from the middle of heat exchanger to the expander for expansion refrigeration, and part expanded air will be fed to the upper column to follow the rectification, and the rest will go out of cold box after it reflows to the main heat exchanger and be warmed.
  • The air will be separated into pure liquid nitrogen and liquid air after being rectified in the lower column. The liquid air in the bottom of lower column goes into the lower part of upper column through subcooling throttling, and then flows into the condensation evaporator as the cold source of condensation rising nitrogen by the column plate.
  • Regarding the liquid nitrogen in the top of lower column, part of it will be withdrawn and go to the top of upper column to follow the rectification, and the rest will be withdrawn as product.
  • The oxygen enrich gas in the bottom of upper column will be withdrawn and go into the subcooler and main heat exchanger to be rewarmed, and then goes out of cold box to be as the regeneration gas of molecular sieve adsorber.
  • The nitrogen in the top of upper column will be withdrawn as the product, and goes out of cold box after being rewarmed in the subcooler and main heat exchanger, and then fed to the piping net after being boosted to the pressure required by the user.
