In this paper, the problem of accumulation and disposal of oil sludge, which includes a stable water-oil emulsion, is touched upon, existing processing methods are studied from the point of view of dividing it into separate components. The classification of physical separation methods, including gravitational sedimentation, separation using centrifugal forces, extraction is given; chemical and combined. It is proposed to use the technology of processing the intermediate layer with a chemical reagent such as SNPCH-4802 with an aromatic solvent. This physico-chemical method for processing tank sludge is to add demulsifier reagents to the emulsion, followed by stirring, heating and separation from water and dirt.
