INSTALLATION FOR PURIFICATION OF OIL-CONTAINING LIQUIDS Russian patent published in 2009 - IPC C02F1/40 

FIELD: purification constructions.

SUBSTANCE: invention relates to devices for purification of oil-containing liquids formed during development of oil wells, washing of vehicles intended for oil products transportation, as well as various reservoirs for their storage or processing. Installation contains body equipped with branch pipes for input of oil-containing water, output of clarified water, for removal of oil products and thickened product. In body formed are chamber of flow rate extinguishing, purification chamber, made in form of two thin-layered precipitation tanks, chamber of collection and accumulation of separate oil products equipped with heating device, and chamber of clarified water, equipped with discharge threshold. Thin-layered precipitation tanks are located horizontally parallel to each other, symmetrical relative to horizontal body axle. In each of them several thin-layered units, in which coalescence plates are placed at angle of 45 degrees to each other, are located in a successive way. Body is also equipped with additional branch pipes for steam input and output, for thickened product dilution and for changing pressure in chamber of clarified water.

EFFECT: creation of device able to purify liquids containing both low- and highly viscous oil products or other hydrocarbons, as well as ensuring reliable equipment operation without reduction of installation productivity.
