Liquid air separation process

Liquid air separation unit usually refers to the air separation unit which directly produces liquid oxygen and liquid nitrogen products. This kind of air separation unit generally does not produce or produce a small amount of gas products. Liquid air separation process can be roughly divided into two methods: first, produce gaseous products, and then use liquefaction device to liquefy or directly produce liquid oxygen and liquid nitrogen products.

Structure of air cooling column

In the air separation unit, the function of air cooling column is to reduce the temperature of air compressed by air compressor. Air cooling column is a kind of hybrid heat exchange equipment. In order to increase the heat transfer area, make the cooling water fully contact with the air and mix completely to enhance the heat transfer effect, the air cooling column usually adopts several structural forms such as packed column, sieve plate column or hollow spray column.
