FIELD: chemistry.
SUBSTANCE: method and device of liquefaction of a gaseous flow, which contains hydrocarbons and acidic compounds, and in which the acidic compounds are removed in a liquefied state, when the gaseous flow, purified from the acidic compounds is gradually cooled to the liquefaction temperature. The method includes cooling the gaseous flow in such a way as to obtain the cooled gaseous flow, containing gaseous hydrocarbons and residual acidic compounds. After that, the obtained gaseous flow, purified from the acidic compounds, is additionally cooled to obtain liquid hydrocarbons.
EFFECT: method improvement.
