Air separation precooling system

Before the air cooling columnand water cooling columnare hoisted in place, the anchor hole shall be cleaned, and there shall be no water and debris in the anchor hole.   After the air cooling columnand water cooling columnare hoisted in place, the perpendicularity of the equipment shall be checked. The perpendicularity shall be ≤ 1/1000 and the total length shall not exceed 10mm.   The bottom of the anchor bolt shall not touch the bottom of the reserved anchor hole. Af...

In the air separation unit of molecular sieve adsorption purification process, after the air is compressed at the last stage of the air compressor, the temperature out of the air compressor reaches 80-90 ℃. Since the adsorption capacity of molecular sieve is inversely proportional to the temperature, in order to improve the working efficiency of molecular sieve adsorber and ensure the purification effect, the compressed air from the air compressor must be cooled to reduce the temperature of the compressed air before entering the purification system.
