Air separation:

Some rare gases such as hydrogen, oxygen, nitrogen, argon and krypton were separated from air. PSA pressure swing adsorption and low temperature distillation were used to prepare them. The use of molecular sieve can effectively remove water, carbon dioxide and other small molecular impurities in these gases, thus meeting the requirements of commercial gas.

Molecular sieve is widely used in air purifier of deep cold air separation unit. Before the raw air enters the low-temperature separation process, the moisture, small molecular impurities and carbon dioxide in the gas need to be removed through the air purification system filled with molecular sieve, and then through various regeneration methods, the service life of molecular sieve is prolonged, which can save energy and reduce the energy consumption of the enterprise Consumption, cost reduction.
