FIELD: gas industry.
SUBSTANCE: invention relates to the processing of hydrocarbon gases. The method for cooling the flow of hydrocarbon raw materials includes cooling the flow of compressed mixed refrigerant and separating the flow of cooled compressed mixed refrigerant into vapor and liquid parts. The liquid part provides the cooling capacity of the first pre-cooling heat exchanger. The vapor part is further compressed, cooled and condensed and used to provide the cooling capacity of the second pre-cooling heat exchanger. The instantaneous vaporization gas separated from the liquefied natural gas is heated and combined with the raw natural gas flow.
EFFECT: reduced raw gas losses.
