PSA Oxygen Technology
PSA oxygen technology is one of the air separating technology for oxygen booming in recent ten years. Compared with traditional cryogenic technology, PSA oxygen technology is known for its low investment, low consumption, low operation-maintenance fee, mild process conditions, simple process flow, high automation, high operation flexibility, short construction duration, and safe performance. Up to now, PSA oxygen technology can replace cryogenic in many circumstances, and the PSA oxygen technology is more economic than cryogenic in running. The main components of air are nitrogen and oxygen, so oxygen can be generated through a selective adsorbent which can separate oxygen from nitrogen in a suitable operation condition. In a pressurized condition, when air flows through adsorption beds with zeolites, nitrogen will be largely adsorbed, while little oxygen will be adsorbed, thus oxygen get enriched. When adsorbent is close to saturation, air will be stopped feeding into the bed,
