PROCEDURE FOR SEPARATION OF WATER-OIL EMULSIONS WITH UTILISATION OF NANO DE-EMULSIFIERS Russian patent published in 2011 - IPC C10G33/04 B82B1/00 

FIELD: gas-and-oil producing industry.

SUBSTANCE: invention refers to oil preparing and can be used in oil producing and oil processing industries to increase rate and depth of separation of water-oil emulsions by means of de-emulsifiers. Here is disclosed the procedure for upgraded quality of water-oil emulsions separation with implementation of nano de-emulsifiers. Dimensions of their molecules are several nano metres. The commodity forms of them generate critical emulsions in oil including coacervate phase of de-emulsifier. The distinguished feature of the procedure is like follows: diametre d_o of particles of coacervate phase of de-emulsifier corresponds to condition 6 nm>d_o≤70 nm.

EFFECT: upgraded quality of separation of water-oil emulsions with utilisation of nano de-emulsifiers wherein dimensions of molecules is of order of several nano metres.
