A known method for purifying gases from carbon disulfide by burning at temperature c to produce sulfuric anhydride. A method is also known for purifying gases from carbon disulfide by cataptic conversion with water vapor at C. The disadvantages of the thermal to catalytic methods are the complexity of the process, the need to use high temperatures, and the process in the presence of expensive catalysts. There is a known method of cleaning gases from sulfur by hydrogen adsorption on active carbon followed by regeneration of the absorber by blowing it with water vapor. The disadvantages of this method are the periodicity of the process, its bulkiness and the need for high-temperature regeneration of the scavenger. 1, in order to simplify and reduce the cost of gas purification from carbon disulfide, the latter was proposed to be carried out by diffusing gases through a gas-permeable polymer membrane, mainly based on polydimethylsiloxane. Polymeric membranes have a high selectivity for carbon disulfide. For example, the gas flow rate of polydimethylsiloxane membranes for carbon disulfide at 30 ° C is 4600, and for nitrogen and oxygen, respectively, 15 and 29 l / m. hour-atm Thus, the separation factor for nitrogen is ZOb, and for oxygen - 158. Example. A gas stream containing 0.03% by volume of carbon disulfide at atmospheric pressure and a temperature of 25 ° C is fed to a diffusion apparatus designed for purification at a rate of 10OO m / h. The diffusion apparatus is a set of diffusion cells with a working surface of the membrane of 25OO m. The cells are made of a 50 µm thick polydimethylsiloxane membrane and a sheet of porous plastic of the Miplast type, which is an arch сом  чейки и одновременно газосборником. catfish and gas collector at the same time.

At the indicated conditions of simplification of the process, the last purity of purification of carbon disulfide in is by diffusion, gases through polygases emitted into the atmosphere, the composition-dimensional gas-permeable membrane predominates 1.7% vol.
