FIELD: chemistry.
SUBSTANCE: invention relates to preparation of oil and can be used in oil-producing and oil-refining industry at the stage of oil preparation for its transportation and refining for separation of water-oil emulsions. Invention deals with de-emulsifier, which represents nanosize aluminium nitride (AIN) powder.
EFFECT: improvement of separation of oil and water phases (without formation of intermediate layers) and deep dehydration of oil (residual water content <0,1%).
