Description:


First step: air goes through filter to remove dust and mechanical impurities

Second step: air goes into compressor to be compressed

Third step: air goes into pre-cooling unit to be cooled to 5~8℃ and to saturated condition

Forth step: air goes into molecular sieve (such as MS1) to adsorb hydrocarbon like H2O, CO2, C2H2

Fifth step: air is divided into three steams: one steam as instrument air, the second steam flows 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steam goes to the main heat exchanger after being boosted and cooled in the boosting end of expander, and then it is withdrawn from the middle of heat exchanger to the expander for expansion refrigeration, and part expanded air will be fed to the upper column to follow the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 goes out of cold box after it backflows to the main heat exchanger and be rewarmed.

Sixth step: air is 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 sub-cooling throttling, and then flows into the condensation evaporator as the cold source of condensation rising nitrogen by the column plate.

For the liquid nitrogen in the top of lower column, part of it will be drawn out and go to the top of upper column to follow the rectification, and the rest will be extracted as product.

 The oxygen enriched gas in the bottom of upper column is drawn out and goes into the sub-cooler and main heat exchanger to be re-warmed, 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 The nitrogen in the top of upper column will be withdrawn as the product, and goes out of cold box after being re-warmed in the sub-cooler and main heat exchanger, and then fed to the piping net after being boosted to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.
