The air is mainly nitrogen and oxygen, of which nitrogen accounts for 78% and oxygen is only 21%.Common methods on the market to separate oxygen and nitrogen: cold separation method, pressure swing adsorption method, and membrane separation method. The cold separation method of deep nitrogen generator is a method commonly used in the industry to separate oxygen and nitrogen. This method is to cool the air to below -150°C and then perform cryogenic distillation. By using this method, we can get liquid nitrogen and liquid oxygen on the basis of getting oxygen and nitrogen. However, this method not only has high energy consumption, a long startup process, and a long process, but also requires high equipment.

There are two ways of pressure swing adsorption. One is to use the selective adsorption characteristics of 5A zeolite. The equilibrium adsorption capacity of 5A zeolite for nitrogen is greater than that for oxygen. Nitrogen is adsorbed, and then oxygen flows out as a product.

The other is to use the characteristics of the adsorption of carbon molecular sieve. The principle is: the equilibrium adsorption capacity of carbon molecular sieve for oxygen and nitrogen is not much different, but because the molecule of oxygen is smaller than that of nitrogen, the diffusion rate of oxygen in the carbon molecular sieve Fast, the adsorption capacity is also large. Oxygen is adsorbed and nitrogen flows out as a product. CAROLADO molecular sieve tower uses pressure swing adsorption method, this method allows us to quickly obtain high concentration of oxygen and stable output without causing waste of resources.If you are interested in any of our products, you can click the link below
