PSA Nitrogen Generator

Introduction

Typical air composition is 78 percent nitrogen and 21 percent oxygen. There are also other molecules in lesser amounts, including carbon dioxide, argon and water.Pressure Swing Adsorption (PSA) technology, which filters out unwanted (i.e., non-nitrogen) molecules. The principle is simple: when the air is drawn through the intake valve, it is sent through a carbon molecular sieve (CMS). The CMS has tiny pores across its surface that are the perfect size for oxygen molecules. Because nitrogen molecules are larger than oxygen molecules, they do not adsorb to the material and pass on undeterred through the CMS.

PSA nitrogen generators have dual-columns: one with fresh CMS for the current adsorption process, and the other that shifts to low pressure to desorb oxygen from saturated CMS for regeneration.

PSA Nitrogen generators can be used in various industries such as Oil & Gas, Plastics, Power Generation, Metal, Pharmaceutical, Food & Beverage, and Electronics, onshore & offshore.
