FIELD: gas industry.
SUBSTANCE: invention relates to a plant for producing liquefied gas. A plant for producing liquefied natural gas (hereinafter – LNG) is described, including units for drying and purifying gas, preliminary and main heat exchangers, a separator, the first and the second expanders, and a compressor connected by means of electric and/or kinematic connection, in which, on a production gas line, there are sequentially located compressor, refrigerator, preliminary heat exchanger, the first section of the main heat exchanger, purification unit, the second section of the main heat exchanger, the first expander, and separator equipped with a LNG output line and a line for supplying reverse gas with the main heat exchanger that is connected to a line for supplying process gas after the second expander forming a line for supplying low pressure gas, on which the preliminary heat exchanger is located.
EFFECT: simplification of the plant and increase in LNG yield.
