FIELD: technological processes.
SUBSTANCE: invention relates to methods of reconstruction of existing plants for low-temperature separation of natural gas and can be used in gas industry. Method of reconstruction of the operating installation of low-temperature gas separation consists in placement of a device with a vertical contact section, which is connected by its lower part to an output part of the horizontal stripping section with a vapor space, before the condensate degassing unit. Contact section is connected to input and low-temperature separators by supply lines of hydrocarbon condensates. Inlet and outlet parts of the stripping section pipe space are connected to the inlet separation gas supply line before and after the recovery unit, respectively. Bottom of the annular space of the inlet part of the stripping section is connected to the unit for degassing the condensate, as well as in equipping the gas discharge line from the condensate degassing unit with the compressor and its connection to the prepared gas discharge line from the installation after the recuperation unit.
EFFECT: invention ensures prevention of formation of flare gases and increased output of prepared gas and liquid products.
