FIELD: heating.
SUBSTANCE: group of inventions relates to a method of cooling a flow of gaseous hydrocarbons. The gaseous hydrocarbon flow is cooled to obtain a liquefied hydrocarbon flow. The gaseous hydrocarbon flow is cooled in one or more heat exchangers using a first refrigerant of the circulation circuit of first refrigerant, in which the said first refrigerant is compressed in the first compressor driven by the first gas turbine engine that is provided by the first inlet air flow, and liquefied using the circuit of second refrigerant, in which the second refrigerant is compressed in the second compressor driven by the second gas turbine engine, which is provided by the second flow of inlet air. The located cooling capacity of the flow of the cooled refrigerant is separated into a first part and a second part in accordance with the typical input parameter. The located cooling capacity of the first part is used for cooling the first flow of the inlet air, as the located cooling capacity of the second part of the flow is used to cool the second flow of the inlet air. The device for cooling a gaseous flow of hydrocarbons is described.
EFFECT: group of inventions is aimed at improving the reliability of the unit for cooling flow of gaseous hydrocarbons.
