1. Pressure swing adsorption to produce oxygen enrichment:

 

The pressure swing adsorption device has the advantages of fast start-up-low energy consumption, simple operation, large load operation adjustment range and simple maintenance. Since the 1980s, with the maturity of pressure swing adsorption technology for oxygen enrichment, where high purity oxygen is not required, pressure swing adsorption has become the world’s main method of obtaining low-cost oxygen, and is widely used in non-ferrous metal smelting (copper smelting). , Zinc smelting, lead smelting, gold smelting, nickel smelting, titanium dioxide, etc.), ferrous metal smelting (blast furnace oxygen-enriched coal injection iron smelting, electric furnace steelmaking, etc.), oxygen-enriched combustion (industrial boilers, glass furnaces, electrolytic aluminum), Chemical gas production (synthetic ammonia, methanol, ethylene, ethylene glycol production, etc.), medical field and sewage treatment (oxygen-enriched explosive gas), pulp bleaching, hydrogen peroxide production, various oxidations in chemistry, cement industry ferric cement, refractory brick manufacturing , Ozone generator, aquaculture, carbon black production, medical care and other fields.

 

 

 

2. Pressure swing adsorption for nitrogen production:

 

Nitrogen is an inert protective gas that is widely used in industries such as grain preservation and insecticide, fruit preservation, and metallurgy, petroleum, and chemical industries. Compared with conventional cryogenic separation methods, pressure swing adsorption has significant advantages such as high purity, large operating flexibility, low investment, low operating cost, high degree of equipment automation, and convenient start-up and shutdown.
