Description

technical field

[0001] The invention relates to methods for treating gaseous mixtures containing hydrocarbons, in particular to the cryogenic separation of gas components, and can be used to treat co-product gases or natural gas. The present invention is particularly helpful in solving problems related to extraction of acid gas (СО) from natural gas 2 and N 2 S) Related tasks. Background technique

[0002] Methods for separating a hydrocarbon-containing gaseous mixture are known in the art and include: cooling the mixture, expanding the mixture or a portion of the mixture, partially condensing the mixture during expansion, separating the mixture in a rectification column Or a part of the mixture, for the purpose of producing products in liquid and gas phases. The treatment (process) of the expanded mixture is carried out by passing the mixture through nozzle channels in which the mixture stream is swirled (swirled) and / or at the nozzle channel inlet and which At the chan...
