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

FIELD: petroleum chemistry.

SUBSTANCE: invention refers to purification of refinery water and can be implemented for extraction of various impurities out of it including oil products. The installation consists of a tank and of a nozzle head piece for water supply assembled coaxially in the cavity of the case made in form of a cartridge open from below. The cartridge is installed in the cavity of the impingement element made in form of a cartridge of a bigger diametre open from top. The upper part of the case free from water is designed to build up air pressure in it. The lower part of the gap between the walls of the impingement element and the tank is connected with a distributor arranged in the lower part of the cavity of the floating compartment of the additional tank. The upper part of volume of the additional tank free from water is designed to drop air pressure in it. The distributor can heat water to temperature close to boiling.

EFFECT: increased degree of aeration of refinery water with simultaneous increased uniformity of aeration of oil containing refinery water volume with fine dispersed bubbles of air.
