INSTALLATION FOR PURIFICATION 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 various impurities out of it including oil products. The installation consists of a tank and of a nozzle head piece for supply of water 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 the 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 the cavity of a floating compartment of an additional tank separated with a vertical impingement partition from a collecting 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.

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.
