The PSA Oxygen Generator is an air separation unit which is based on molecular sieves selective adsorption of nitrogen from air and can continuously generate gas oxygen with a purity 90~ 95% at ambient temperature, and the adsorbed nitrogen can be desorpted by decreasing the adsorbed bed pressure resulting cyclical adsorption-desorption operation.
The traditional method of obtaining oxygen is to liquefy air and then carry out distillation at temperatures of around -180℃.The PSA generator can be operated under normal atmosphere, and its advantages are listed as following:
◆ Low Production Cost.
◆ Simple Process and Less Equipment, High Automation and Operation Convenience.
◆ Quick Starting and Easy Stopping. The system can provide product gas in five minutes after starting and also can be operated intermittently.
◆ Low working pressure and safely.
◆ Good Flexibility. The purity and output of the product gas can be easily adjusted.
