FIELD: gas industry.
SUBSTANCE: invention relates to methods of preparing hydrocarbon gas for single-phase transfer by low-temperature condensation and can be used in oil and gas industry. Disclosed is a method, according to which crude gas is separated in separation zone of refluxer into water condensate, hydrocarbon condensate and gas, which is subjected to contact with hydrate formation inhibitor or absorbent moisture and reflux flowing down from upper refluxing section, and then cooled prepared gas under refluxing conditions. Partially cooled and released from reflux gas then stays in contact with reflux flowing down from upper refluxing section, and is cooled by an external coolant under refluxing conditions, and after heating in refluxing section is removed from plant. Optionally, at one of steps of cooling gas or contact, a portion of obtained hydrocarbon condensate is fed as absorbent, and inlet gas separation is also performed.
EFFECT: technical result is reduction of power consumption and metal input.
