Sichuan Variable Pressure Adsorption Air Separation for O2 and N2 Technology and Equipment

I. Variable pressure adsorption for oxygen enrichment:

Variable pressure adsorption device has the advantages of fast start-up - low energy consumption, simple operation, wide range of load operation adjustment and simple maintenance. Since the eighties, with the maturity of VAO technology, VAO has become the main method of obtaining low-cost oxygen in the world without the need of high-purity oxygen, which is widely used in non-ferrous metal smelting (copper, zinc, lead, gold, nickel, titanium dioxide, etc.), ferrous metal smelting (oxygen-rich coal blasting in blast furnaces to make iron, electric furnaces to make steel, etc.), oxygen-enriched combustion (industrial boiler, glass kiln.), chemical gas making (ammonia, methanol, aluminium), chemical gas making (ammonia, methanol, glass furnace.), and chemical gas making (synthetic ammonia, methanol, aluminium), Aluminium electrolysis), chemical gas production (ammonia, methanol, ethylene, ethylene glycol production, etc.), the medical field and sewage treatment (oxygen-enriched explosion), pulp bleaching, hydrogen peroxide production, various oxidation of chemistry, cement industry, cement, refractory bricks manufacturing, ozone generators, aquaculture, carbon black production, medical care and other fields. 

Second, pressure change adsorption nitrogen:

Nitrogen is an inert protective gas, widely used in food preservation and insecticide, fruit preservation, and metallurgy, petroleum, chemical and other industries. Compared with the conventional deep-cooling separation method, pressure change adsorption has the significant advantages of high purity, high operating flexibility, low investment, low operating cost, high degree of automation of the device, and convenient opening and stopping.
