Pressure swing adsorption (PSA) is a technology used to separate some gas species from a mixture of gases under pressure according to the species' molecular characteristics and affinity for an adsorbent material. It operates at ambient temperatures and differs significantly from cryogenic distillation techniques of gas separation.
Specific adsorptive materials (e.g., zeolites, activated carbon, molecular sieves, etc.) are used as a trap,
preferentially adsorbing the target gas species at high pressure. The process then swings to low pressure to desorb the adsorbed material.
Technique principle
♦ Purified air drying treatment, role of pressure swing adsorption to achieve separation of oxygen and nitrogen
♦Due to selective adsorption characteristics of zeolite, nitrogen molecule is adsorbed in zeolite, and oxygen concentration in the gas phase is obtained, as product output.
♦System device has two absorption towers, production of oxygen adsorption tower, tower desorption recycling, pay latent and continuo
