METHOD FOR PREPARING HYDROCARBON MATERIAL WITH GASEOUS PHASE FOR TRANSPORTATION Russian patent published in 2015 - IPC B01D53/00

Abstract RU 2569348 C1

FIELD: oil and gas industry.

SUBSTANCE: invention suggests the method including gas delivery from well pads for separation, three-stage separation with cooling of gas flow, introduction of volatile inhibitor of methanol hydrating into it, output of liquid from separators, separation into hydrocarbon and methanol phases, delivery of liquid hydrocarbons from the first separation degree to counterflow contacting with separated gas to the last separation stage; and this method is featured by the fact that hydrocarbon fraction composition HFC with potential of non-soluble hydrating inhibitor of hydrocarbon fractions boiling within the range of 23-290°C is introduced into flow of hydrocarbon gas at delivery through gathering line for separation and before delivery for blowing off at the first stage separation.

EFFECT: invention allows increase in efficiency of production at oil and gas and gas condensate deposits at reduced consumption of toxic soluble inhibitor of methanol hydrating and reduced burden to environment.
