FIELD: cryogenic condensation plants. SUBSTANCE: in a cryogenic condensation plant used for removal of gasoline in the process of liquefaction of natural gas a gas flow, preliminarily cooled down in a heat exchanger to the temperature at which at least the gasoline component gets condensed, is fed to two successively connected separating columns. In the first column gasoline is absorbed, and the liquid-gas mixture is separated, the liquid is fed to the second column. In the second column a steam flow is produced, which is removed from the upper part and preserved for processing to liquefied natural gas, and a flow from the lower part of the column containing the natural gas liquefaction products. Cooling for condensation of hydrocarbon gases in the heat exchanger is regulated by means of an automatically controlled bypass flow by-passing the heat exchanger in accordance with the measured steam consumption from the second separating column. The quantity of condensed liquid corresponds to the consumption of steam flow-discharged from the upper part of the second separating column. EFFECT: perfected control of condensation and operative control, enhanced efficiency of removal of gasoline from the flow. 10 cl, 1 dwg
