PLANT TO SEPARATE CЕC HYDROCARBONS AND HIGHER FROM WATER Russian patent published in 2011 - IPC B01D53/00 C10G5/00 

FIELD: process engineering.

SUBSTANCE: invention relates to oil and gas treatment and may be used in oil-and-gas industry. Proposed plant comprises housing, internal perforated tube and external perforated shell ring, tightly separated chambers receiving initial gas mix and cooling water and discharging cooling water, C₅ fraction discharge branch pipe and C_1-4 hydrocarbon fraction discharge branch pipe, rotary filter and filter cooling system made up of cooling tubes. Rotary filter is made up of cylindrical cartridges filled with sorbent from polyolefin fibers and arranged between, internal tube and external perforated shell ring. Cartridges are fitted one into another and arranged between cooling tubes tightly connected with upper cooling water distributor and cooling water drain hollow shaft. Cartridge sidewalls are made from perforated metal with cell size of 1-3 mm. Proposed plant comprises also absorber for afterpurification of C_1-4 hydrocarbons consisting of two columns filled with sorbent, condensate collector, C_1-4 fraction discharge branch pipe and system to feed compressed gas for regeneration purposes.

EFFECT: higher quality of gas purification and C_1-4 fraction separation by simple procedure in continuous processing conditions.
