The process of separation of oil sludge, which is obtained after cleaning the oil refining units of the Bukhara oil refinery, is presented. Methods of obtaining petroleum liquid rafinate using several experimental laboratory installations for liquid-phase separation of oil sludge in a centrifugal force field with the use of a deemulgator "Disolvan-4411" and sawdust from the processing of old furniture of local raw materials are used. The composition and amount of heavy sediment and clarified oil products from oil sludge were obtained
