DEVICE FOR PREPARING NATURAL GAS FOR TRANSPORTATION Russian patent published in 2024 - IPC B01D53/02 F25J3/00 

FIELD: transportation of hydrocarbon gas.

SUBSTANCE: device for preparing natural gas for transportation includes a source gas separation unit with outlets for hydrocarbon condensate and water. The separation unit is connected to the adsorption drying and gas topping unit with outlets of prepared gas, waste gas, hydrocarbon condensate and water. The adsorption drying unit is connected to the booster compressor station through the prepared gas outlet line. The source gas separation unit together with the adsorption drying unit is connected by a hydrocarbon condensate removal line to the hydrocarbon stabilization unit. The hydrocarbon stabilization unit is equipped with a stable condensate outlet and a stabilization gas outlet, which is connected to the line for own needs and to the compression unit. The outlet from the compression unit is connected either to the source gas flow, or to the exhaust gas outlet, or to the prepared gas outlet. The booster compressor station is connected by an outlet line for a portion of the prepared gas with an additionally installed unit for producing compressed natural gas (CNG), equipped with CNG and hydrocarbon condensate outlets.

EFFECT: invention makes it possible to increase the operating efficiency of a hydrocarbon gas preparation device.
