Dryer PSA Nitrogen Generator Recovery System

PSA Nitrogen Generator

Description

A PSA Nitrogen Generator operates based on the principle of Pressure Swing Adsorption. It utilizes specialized adsorbent material, typically carbon molecular sieves (CMS), to selectively adsorb oxygen molecules from compressed air, thereby producing high-purity nitrogen gas.

Compressed air enters the generator and passes through filters to remove impurities. The filtered air then enters a vessel containing the adsorbent material. Under pressure, the CMS material selectively adsorbs oxygen molecules, allowing nitrogen molecules to pass through relatively unaffected. This separation is achieved due to the different adsorption characteristics of oxygen and nitrogen on the CMS material. Consequently, a stream of nitrogen gas with significantly higher purity is obtained.

The adsorption process continues until the CMS material becomes saturated with oxygen. At this point, the pressure is reduced, leading to the swing phase of the process. By lowering the pressure, the adsorbed oxygen molecules are released from the CMS material, allowing it to regenerate and prepare for the next cycle.

To ensure a continuous nitrogen gas supply, PSA Nitrogen Generators often employ multiple vessels or adsorption beds. While one bed is in the adsorption phase, providing nitrogen gas, the other bed undergoes regeneration. This cycling process ensures a constant and uninterrupted flow of high-purity nitrogen gas.

In summary, PSA Nitrogen Generators utilize the selective adsorption property of specialized adsorbent material to separate oxygen from compressed air, resulting in the production of high-purity nitrogen gas. The process involves adsorption of oxygen under pressure, swing phase for regeneration, and the use of multiple beds for continuous operation.

PSA full name: Pressure Swing Adsorption, Chinese meaning: Pressure swing adsorption. PSA is a new gas separation technology, since the late 60's and early 70's in foreign countries has been rapid development, its principle is the use of molecular sieve on different gas molecules "adsorption" performance differences and separate the gas mixture, it is based on air as raw material, Nitrogen and oxygen are separated from the air by the selective adsorption of nitrogen and oxygen with an efficient and highly selective solid adsorbent.
