LIQUID HYDROCARBON PURIFICATION METHOD Russian patent published in 2012 - IPC C10G31/09 C10G32/02 B01D17/00 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to liquid hydrocarbon purification method in which preliminary separation and coagulation is performed on metal porous partition of the filter at twisting of continuous medium flow via spiral generatrixes made from dielectric material and installed in a gap between its plastic housing and partition and action of electric field when static charge is induced on inner surface of housing with induction of the charge of opposite sign on outer surface of metal porous partition, there tangentially supplied is flow with the main mass of mechanical impurities and water with size which is more than nominal pore size of prefilter to the separator shell with flow swirling between its inner wall reinforced with foamed metal - high-porous cellular material (HPCM) with coagulation properties, and shaped guide from plastic material fixed on pylons from dielectric material in upper part of the shell with induction of electric field in a gap between the latter; sediment is transported back to the pump inlet, and filtrate is supplied with additional pump for separation on porous partition of filter with coalescing properties from polymer of spatial-globular structure (SGS); at that, the rest part of mechanical impurities and water with size which is more than nominal pore size of filter is constantly supplied with turbulent medium flow to supply main line of separator; purified filtrate is cooled in heat exchanger with further removal of water fog on fine filter from SGS of polymer.

EFFECT: increasing purification efficiency of hydrocarbon media.
