Prospects of using desublimation in the technologies of obtaining inert gases are shown. Physical principles of their separation from binary and multicomponent mixtures due to the phase transition «gas-solid body» are considered. The effect of temperature on the concentration of the outgoing stream and the degree of extraction of the desired product has been estimated. Examples of the use of desublimation in the processes of xenon enrichment, separation of light inert gases, and purification of gas concentrates from high-boiling impurities are given.
