INSTALLATION FOR ELECTROLYTIC PURIFICATION OF OIL CONTAINING WATER Russian patent published in 2009 - IPC C02F1/465 

FIELD: petroleum chemistry.

SUBSTANCE: invention refers to electrolytic purification of refinery water containing emulsified and colloidal dispersed contaminations and can be implemented for purification of refinery water at oil, chemical and gas industries. The installation of electrical purification of refinery water from suspended substances and oil products consists of a case, of branches for inlet and outlet of water, of a source of direct current and of electrodes arranged so, that two or more porous cathodes successively assembled downstream create cathode chambers between them, two or more porous anodes create anode chambers between them, also the last cathode and the first anode form between-electrode chamber; all chambers are equipped with branches of floating sludge discharge; in addition, the first cathode has potential more negative, than the second cathode, the second one has potential more negative, than the third one an so on; while the first anode has potential more positive, than the second anode, the second anode has potential more positive, than the third one and so on; anodes are fabricated out of material insoluble at anode polarisation.

EFFECT: increased efficiency of refinery water purification.
