FIELD: oil, gas and coke-chemical industries.
SUBSTANCE: method is proposed for processing oil sludge, including its intake from a storage through a self-cleaning filter by means of a high-efficiency pump, heating in a heat exchanger of tubular or other type up to 40÷60 °C and feeding into apparatus with heated jacket and mixer, equipped with water meters, and demulsifier to obtain thermodynamically unstable water-oil system, where demulsifier is an aqueous suspension of calcium sulphate, or mixture thereof, and weight ratio of oil sludge:water:demulsifier before feeding into hydrodynamic accelerator of fine dispersion is (17÷25):(0.1÷12): (>0.1÷0.10), followed by separation of colloidal water-oil emulsion into oil and water-sludge fraction at electro desalting and dehydration plant with sludge obtained oil product and recycling water-slurry suspension.
EFFECT: technical result is improvement of processing line of oil sludge processing, formed at oil production and processing stages, with simultaneous improvement of process efficiency and quality of obtained oil products.
