Columns with the mass-transfer packing units are widely applied in the technologies of industrial gases extraction and purification. The difference in components properties and a wide range of concentrations of separated mixtures complicate the use of well-known calculated dependencies when designing the rectification devices of the mentioned type. In many cases the correct information can be obtained only experimentally using specific equipment. In each separate case it’s necessary to solve the problem of cryogenic supply to the rectification process. The general purpose apparatus, which operates in the range of temperature from 80 to 300 K, was developed for investigation of the separation process of different gas mixtures. The results of testing of the multifunctional rectification column in the mode of deep СО2 purification from low-boiling impurities are considered.
