METHOD OF PREPARATION OF HYDROCARBON GAS FOR TRANSPORTATION Russian patent published in 2001 - IPC

FIELD: gas-and-oil industry; hydrocarbon gas dryers; treatment of hydrocarbon gases at field and plants, especially in case of reduction of formation pressure in gas pools at shift to late stage of development. SUBSTANCE: proposed method includes separation, compression, cooling and absorption drying of gas, delivery and discharge of saturated absorbent for regeneration, compression and cooling of dried gas; specific feature of proposed method consists in directing the part of high-pressure dehydrated gas to ejector unit as active flow and returning it to technological cycle. According to one version, saturated absorbent is fed to technological cycle from drier through ejector for preliminary drying of raw in ejector unit. After ejector unit, saturated absorbent is entrapped by filter-separator and is directed to absorbent regeneration unit. EFFECT: improved quality of commercial gas with no increase in capital and operational outlays. 2 cl, 1 dwg
