METHOD OF DEHYDRATING HIGHLY STABLE WATER-HYDROCARBON EMULSIONS OF NATURAL AND TECHNOGENIC ORIGIN AND DEVICE THEREFOR Russian patent published in 2016 - IPC C10G7/04 C10G33/00 

FIELD: oil industry.

SUBSTANCE: invention relates to a method for dehydration highly stable water-hydrocarbon emulsions, including a mixture of oily wastes, decomposition products and cleaning of lubricating-cooling liquids, barn sludge, liquid pyrolysis products, heavy pyrolysis resin, an intermediate layer of oil, natural bitumen and other water-hydrocarbon emulsions. Method of dehydrating highly stable water-hydrocarbon emulsions of natural and technogenic origin is implemented by heating, generation and evaporation of water phase from volume of boiling liquid, formed vapour from top of evaporator is directed to condenser-cooler, where vapour is condensed, fed into a settler with separation of condensate into a hydrocarbon fraction and water, respectively, and dried product from lower part of evaporator in case of compliance is pumped into a container for collection of dry product, method is characterised by dehydration of water-hydrocarbon emulsion is carried out in conditions of continuous transfer residue from lower part of evaporator to its upper part with provision of additional heating and cleaning bottom liquid from mechanical impurities. Device for implementing said method is also disclosed.

EFFECT: technical result is higher efficiency and reliability of dehydration of various types of water-hydrocarbon emulsions.
