Principle

The device USES chemical absorption deoxygenation technology to remove oxygen impurities in the gas and obtain high purity gas.

It is suitable for the raw gas with purity of 99.9% or more. Generally, the waste nitrogen gas produced by the cryogenic air separation oxygen station is further deoxygenated to obtain high-purity (99.9995% ~ 99.9999%N2) nitrogen, or the cryogenic air separation nitrogen equipment is reduced in purity after years of use. Further deoxygenation purification is required to obtain high-purity nitrogen.

Due to the purification device adopts unique novel parallel regeneration - series work process, solves the due to "dissolved hydrogen" characteristics of the catalyst has caused the problem of pollution of hydrogen gas products, realize high purity oxygen and hydrogen in the gas products miscellaneous quality are less than 1 PPM of index, at the same time to achieve both energy conservation and purification operation to reduce costs, this device can also be applied to same type NCHa gas purification device of gas ranges。
