Carbon Molecular N2 Nitrogen Generator

Using air as raw material, carbon molecular sieve as adsorbent, and pressure swing adsorption principle, the method of separating nitrogen and oxygen by using carbon molecular sieve to selectively adsorb oxygen and nitrogen is generally known as PSA nitrogen production.

This method is a new nitrogen production technology developed rapidly in the 1970s. Compared with the traditional nitrogen production method, it has the advantages of simple process flow, high degree of automation, fast gas production (15~30 minutes), low energy consumption, product purity can be adjusted in a large range according to the needs of users, convenient operation and maintenance, low operating cost, and strong adaptability of the device.

Therefore, it is quite competitive in nitrogen production equipment below 1000 Nm3/h, and is increasingly welcomed by medium and small nitrogen users.

PSA nitrogen production has become a medium and small Preferred method for small nitrogen users.

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.
