| description | The invention relates to a technique for processing associated or natural gas, more specifically to a process for the low-temperature separation of the components of a gas. The proposed invention is intended to achieve the technical result of increasing the degree of purification of the output gas. This technical result is achieved in that in the gas mixture separation method according to the invention, which includes cooling the mixture, expanding the products obtained therefrom, pumping at least a part of the products through a distillation column, expanding the mixture in a swirling flow in a nozzle with the division of the flow into a flow enriched with components heavier than methane and a flow depleted of such components, and heating the depleted flow by cooling the products obtained from the mixture, the heated gas flow is compressed in a compressor and cooled in an air cooling apparatus, part of the gas product obtained is used as output product, while the other part is further cooled and expanded and the expansion products are fed to the column and/or mixed with the gas phase products passing from the column into the nozzle. Furthermore, the enriched flow or a part thereof is used as a cooling agent for cooling the mixture or the products obtained therefrom, and is compressed, cooled with the aid of the air cooling apparatus and fed into the mixture |
