Nitrogen Liquifier Working Principle

The cryogenic mixed refrigerant throttle refrigerator is adopted in this nitrogen liquefier. It is based on the regenerative multi-component mixed refrigerant throttle refrigeration cycle. The high, middle and low boiling point pure components are selected to compose multi-component mixed refrigerants. The relay matching of effective refrigeration temperature zones of each boiling point component is realized. It can be cooled from ambient temperature to -196 ° C, the purpose of nitrogen liquefaction (-180 ° C @ 0.6 MPa) is achieved.

WORKING PRINCIPLE:
PSA technique (Pressure Swing Adsorption, PSA for short):it's a kind of advanced gas separation technology, based on physical adsorption of gas molecule on the internal surface of adsorbent (porous solid substances), using adsorbents in the same pressure easy to absorb the high boiling point gas, difficult to absorb low boiling point gas, and under high pressure adsorption amount of absorbed gas increases, under low pressure adsorption of absorbed gas to reduce the features to achieve gas separation. This process under pressure adsorption of impurities, under reduced pressure adsorption of impurities, make the adsorbent regeneration, is the PSA cycle.
