FIELD: gas industry.
SUBSTANCE: inventions relate to integrated gas treatment plants with the production of liquefied natural gas (LNG). The installation is described, including an inlet separator, intermediate and additional separators, an LNG separator, a recuperative heat exchanger and a recuperative heat exchanger of the LNG unit, a refrigerator and refrigerators of the LNG unit, an expander and an expander of the LNG unit connected to the compressor and the compressor of the LNG unit, respectively, a demethanizer, reducing devices, as well as a fractionation unit, a drying and gas purification unit. The second installation option differs in that the second refrigerator is located on the bypass line of the recuperative heat exchanger of the LNG unit. The third installation option differs in that the LNG unit does not contain a second refrigerator, and the regenerative heat exchanger is multiflow.
EFFECT: increase in the output of gas condensate.
