NATURAL GAS TREATMENT DEVICE Russian patent published in 2024 - IPC B01D53/00 B01D53/02 B01D53/26 F25J3/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to devices for preparation of natural gases for transport by adsorption method, including drying and stripping of gas, and can be used in gas, oil and other industries. Described is a natural gas preparation device, which includes an initial gas separation unit with hydrocarbon condensate and water outlets, which is connected to the gas adsorption drying and stripping unit, equipped with the regeneration gas heating tubular furnace, with the gas, hydrocarbon condensate and water removal after the adsorbent regeneration, and which is connected to the booster compressor station (BCS) through the prepared gas discharge line, which is connected through the regeneration gas line to the gas adsorption drying and stripping unit, which is also connected together with the initial gas separation unit by a hydrocarbon condensate discharge line with a hydrocarbon stabilization unit equipped with outlets of stable condensate and stabilization gases, which is connected to the line for auxiliary needs and to the compression unit, the output of which is connected either to the flow of the initial gas, or to the outlet of the waste gas of regeneration, or to the outlet of the prepared gas, characterized by that gas adsorption drying and stripping unit equipped with regeneration gas heating tubular furnace, is connected by regeneration gas line before entering tubular furnace with additionally installed gas compressor unit (GCU) flue gas heat recovery unit, which is connected to BCS unit equipped with gas compressor unit.

EFFECT: implementation of resource-and-energy-saving technology, providing reduction of operating costs with additional heating of regeneration gas, due to convectional heat exchange, using heat of exhaust flue gases coming out of BCS GCU gas turbine.
