COMPOSITION FOR DESTRUCTION OF OIL-WATER EMULSIONS AND FOR REMOVAL AND PREVENTION OF ASPHALT-RESIN-PARAFFIN DEPOSITS Russian patent published in 2013 - IPC C09K8/524 C10G33/04 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil production industry, and namely to compositions for destruction of oil-water emulsions and for removal and prevention of asphalt-resin-paraffin deposits (ARPD), and can be used at oil fields for protection of the equipment. Composition for destruction of oil-water emulsions and for removal and prevention of asphalt-resin-paraffin deposits includes aluminium chloride, solvent - mixture of toluene, benzene and acetone at their ratio in the mixture, which is equal to 4.2:1.0:1.3-2.6 respectively, or mixture of toluene and acetone at their ratio in the mixture, which is equal to 1.27-1.65:1 respectively, or o-xylene, surface active substance - synthanol, or oksinol, or neonol, or sinterol. The specified composition contains a corrosion inhibitor, and namely aminoamide, or polyethylenepolyamine benzyne ammonium chloride, or imidasoline.

EFFECT: higher efficiency and protection degree of oil-field equipment, as well as enlarged range of compositions for protection against ARPD.
