FIELD: process engineering.
SUBSTANCE: invention relates to relates to plant intended for processing oil-containing wastes and can be used in petroleum, oil processing and other industries. Proposed plant comprises settling basin to separate liquid and solid phases and oil separator. Oil separator is connected with oil collector and, via filter, with multi-stage vacuum-evaporator unit designed to evaporate liquid and produce concentrates solution of salt and condensate. Concentrated salt solution outlet is communicated with combustion chamber of the plant for thermal treatment to produce dry concentrated salt. Condensate outlet is communicated, via condenser, with bio filter and purified water accumulator.
EFFECT: efficient method of solid and/or liquid oil-containing wastes, optimum refinery process, improved ecology.
