OIL SLURRY PROCESSING PLANT Russian patent published in 2019 - IPC B09B5/00 B09C1/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas production and oil refining industry and can be used for processing and recycling old oil slurries and oily lands. Facility for processing oil slurries includes in-series connected oil sludge mixer with surfactant solution, settling tank, mixer with rock-forming additive, a platform for forming compost collars with aeration system with heated air as a solid phase collector, a circulating loop of an aqueous surfactant solution, which consists of an oil sludge mixer with a surfactant solution, a settling tank with a drainage system, a drain pump, a storage tank, a hydrophobic filter, a surfactant dispenser and a heat exchanger. Dispenser is configured to be dosed into mixer of rock-forming organomineral additive. In the body of the compost collar there arranged in alternating rows are electronegative and electropositive electrodes. Electrodes of the same polarity are connected by conductors, and resistance of load is connected between electrodes of different polarity.

EFFECT: use of this invention provides reduced time of composting oil slurries with production of commodity soils.
