Brief introduction of chemical industry PSA nitrogen gas making machine
- Dec 10, 2018 -

In the process of using chemical industry PSA nitrogen gas making machine, the air passes through the filter to remove dust and mechanical impurities, then enters the air compressor, compresses to the required pressure, and undergoes strict degreasing, water removal, dust removal and purification treatment, and the output is clean. The purpose of compressed air is to ensure the service life of the molecular sieve in the adsorption tower. There are two adsorption towers equipped with carbon molecular sieves. When one tower is working, the other tower is decompressed under reduced pressure.

The treated air enters the working adsorption tower of the chemical industry PSA nitrogen gas making machine, and oxygen, carbon dioxide and water are adsorbed by the molecular sieve, and the gas flowing to the outlet end is nitrogen and a trace amount of argon and oxygen. The desorption column detaches the adsorbed oxygen, carbon dioxide and water from the molecular sieve micropores into the atmosphere. In this way, the two towers are carried out in turn, the nitrogen and oxygen separation is completed, and the nitrogen gas is continuously output.

The nitrogen output from the chemical industry PSA nitrogen gas making machine enters the nitrogen purification equipment, and at the same time, an appropriate amount of hydrogen is added through a flow meter, and a trace amount of oxygen in the hydrogen and nitrogen in the deoxidation tower of the purification equipment is catalytically reacted to remove oxygen and then pass through the water. The condenser is cooled, the steam separator is dehydrated, and then dried deep by a dryer to obtain high purity nitrogen.
