The global consumption of krypton and xenon is expected to grow by 1,5–2 times in the nearest decades. The manufacturers of heavy inert gases will be compelled to extract gases even from rather poor concentrates due to the limited raw-material sources. It is necessary to use the freezing, adsorption and rectification processes while developing installations for the proficient extraction of these gases with small losses and power expenses. The characteristics of the thermodynamic processes of the inert gases freezing and their adsorption extraction from mixtures have been studied in the article. The highly efficient pilot and production plants for the extraction of krypton and xenon have been described.
