Effect of Cryogenic Distillation and Chemical Absorption on the Argon Concentration in Krypton Purification

Cryogenic distillation and chemical absorption are two important means of inert gas purification. Experiments show that the order of the two methods has an effect on the final purification result. In order to verify the relationship between the retention of argon and the order of the two methods, experimental verification was designed. At the same time, the numerical simulation was carried out by using the principle of low temperature distillation, and the influence results of the two methods on the argon content after gas purification was obtained.
