NATURAL GAS TREATMENT PROCESS Russian patent published in 2001 - IPC

Abstract RU 2161526 C1

FIELD: oil and gas production. SUBSTANCE: process includes stepped separation accompanied by cooling gas stream between separation steps, adding hydrate-formation inhibitor (methanol), withdrawing liquid phase from separators, and separating the latter into hydrocarbon and water-methanol phases. Water-methanol phase is brought into countercurrent contact with separated (purging) gas in the first separation step. Stream isolated from thus treated water-methanol phase is combined with liquid phases coming from the last and intermediate separation steps. EFFECT: enhanced process efficiency. 1 dwg
