Description:


This ASU adopts a process in which air is purified by normal temperature molecular sieve, refrigerated by booster expansion turbine; the fractionating cloumn adopts the external compression process with sieve plates techology. This ASU is able to run economically and properly in the load adjustment range 80% ~105% of production capaicty, without adding any other equipment. Its process procedure is as the followings:


Following the elimination of dust and other mechanical impurities from process air in an air filter, the process air enters air turbo- compressor where it is compressed to a certain pressure, and then it is cooled in a cooling column. The feed water to air cooling column is divided into two section, the circulating water treated with water is used in the lower section of cooling column, while the cryogenic water cooled by water cooling column is used in the upper section of cooling column. And a demister is set on the top of air cooling column to prevent moisture dragout and elimination of water drops in air.

Process air out of air cooling column enters the alternately - operated molecular sieve adsorbers where such impurities contained in air as moisture, CO2 and C2H2 etc. are adsorbed.

The cleaned process air is divided into 3 streams: A small portion of the purified processed air is drawn out as instrument air. One portion enters main heat exchanger E1 to be cooled down to saturation temperature with reversed gas and then enters lower tower C1; Another portion of the air with its quantity equals to the swelling quantity to the booster, supercharged by the booster, then cooled to normal temperature by cooling water before entering the main heat exchanger E1. It is drawn out from the middle of the main heat exchanger and expanded by the expander ET. Most part of the expanded air is fed to the upper column for rectification, the air is initially rectified in the lower column, where liquid air is obtained at its bottom, pure liquid nitrogen is obtained at its top. The liquid air and pure liquid nitrogen drawn out from the lower column are subcooled in the liquid air and liquid nitrogen subcooler E2 before entering the upper column. After further rectification in the upper column, product gaseous oxygen and liquid oxygen with low pressure is obtained at its bottom, oxygen gas is fed out of cold box to GOX pipe network by compression of oxygen compressor after rewarmed through main heat exchanger. Meanwhile, partial liquid oxygen is drawn out of the bottom of upper column to the liquid oxygen storage system.

Pure gaseous nitrogen is drawn out of the top of upper column to be rewarmed in subcooler and main heat exchanger before it is fed out of cold box, and then it is fed to GAN pipe network after compession of nitrogen compessor.

Waste nitrogen gas is drawn out of the upper portion of upper column to and rewarmed in subcooler and main heat exchanger before it’s fed out of cold box for meeting the requirement of regeneration gas for molecular sieve firstly, and then the rest is delivered to water cooling column.

LOX back-up system: liquid oxygen in storage tank is supercharged by LOX pump before it is rewarmed in LOX vaporizer to be gaseous oxygen to GOX pipe network.

LIN back-up system: liquid oxygen in storage tank is supercharged by LIN pump before it is rewarmed in LIN vaporizer to be gaseous oxygen to GAN pipe network.
