The operation of section for gas mixtures reception on the basis of inert gases was analysed. In-fluence on economy of the liquid cryogen products consumption the different factors on example of the argon are shown. They are calculated losses of liquefied gas under its transportation and storage, the dependence of the relative losses from volume got gas products is studied. Some variants of the organization of the vapour system utilising are offered, determined the economic feasibility of their implementation.
