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 elimination of dust and other mechanical impurities from process air in an air filter, the process air enters air compressor to be compressed, and then enters precooling system to be cooled to approx 5~8℃ and to be reached saturated condition.
  • The compressed air enters one of molecular sieve adsorbers (such as MS1) where such impurities contained in air as moisture, CO2, C2H2 and hydrocarbon are adsorbed by molecular sieve.
  • The air out of adsorber will be divided into three steams: one steam will be withdrawn as instrument air, the second steam goes into the main heat exchanger E1 directly to be cooled, and then part of it will reach saturation temperature after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steam goes to the main heat exchanger after being boosted and cooled in theboosting end of expander , and then it is withdrawn from the middle of heat exchanger to the expander for expansion refrigeration, and part expanded air will be fed to the upper column to follow the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  • Regarding the liquid nitrogen in the top of lower column, part of it will be withdrawn and go to the top of upper column to follow the rectification, and the rest will be withdrawn as product.
  • The oxygen enrich gas in the bottom of upper column will be withdrawn and go into the subcooler and main heat exchanger to be rewarmed, and then goes out of cold box to be as the regeneration gas of molecular sieve adsorber.
  • The nitrogen in the top of upper column will be withdrawn as the product, and goes out of cold box after being rewarmed in the subcooler and main heat exchanger, and then fed to the piping net after being boosted to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.
  • In order to make sure the safe running of plant, a small part liquid in the condensation evaporator should be discharged out of column regularly to avoid the accumulation of hydrocarbon, especially acetylene.
