HYDROCARBON GAS TREATMENT PLANT Russian patent published in 2022 - IPC B01D53/00 C10G5/00 

FIELD: hydrocarbon gas treatment plants.

SUBSTANCE: invention relates to a hydrocarbon gas treatment plant. A hydrocarbon gas treatment plant is described, which includes a gas separation unit with outlets for separated gas, hydrocarbon condensate and water, an adsorption drying and gas stripping unit with outlets for prepared gas and gas after adsorbent regeneration, a cooler and a high-pressure separator of cooled gas after adsorbent regeneration with regeneration waste gas, hydrocarbon condensate and water outlets, hydrocarbon condensate outlet from the gas separation unit and hydrocarbon condensate outlet from the high pressure cooled gas separator after the adsorbent regeneration are connected to the hydrocarbon stabilization unit equipped with stabilization gases, stable condensate and water outlets, stabilization gases outlet connected to the compression unit, while the outlet of the regeneration exhaust gas after the regeneration of the adsorbent is connected to the hydrocarbon stabilization unit, containing a throttle communicated with the low temperature with a rotary separator equipped with a stabilization gas and hydrocarbon condensate outlet, the hydrocarbon condensate outlet line is connected after the throttle to the hydrocarbon condensate outlet line from the gas separation unit and from the high-pressure separator after the adsorbent is regenerated and is connected to a medium-pressure separator equipped with outlets for stabilization gases, water and hydrocarbon condensate outlet connected through a throttle to a low-pressure separator equipped with stabilization gas and stable condensate outlets.

EFFECT: reduction of losses of C₅₊ hydrocarbons and increase in the production of stable hydrocarbon condensate.
