The method of using air as raw material, carbon molecular sieve as adsorbent, and pressure swing adsorption principle to selectively adsorb oxygen and nitrogen by carbon molecular sieve to separate nitrogen and oxygen is commonly known as PSA nitrogen production. This method is a new nitrogen production technology that rapidly developed in the 1970s. Compared with traditional nitrogen production methods, it has the advantages of simple process flow, high degree of automation, fast gas production (15-30 minutes), low energy consumption, adjustable product purity within a large range according to user needs, convenient operation and maintenance, low operating costs, and strong device adaptability. Therefore, it is highly competitive in nitrogen production equipment below 2000Nm3/h and is increasingly popular among small and medium-sized nitrogen users. PSA nitrogen production has become the preferred method for small and medium-sized nitrogen users.
