Abstract
An invention is disclosed whereby refinery waste emulsion streams such as API slop oils, desalter rag layer emulsions, mud pit sludges and the like having high viscosities and specific gravity approaching that of water can be treated for the recovery of processable oil values which had previously been unavailable by adding a sufficient amount of a light hydrocarbon diluent to the emulsion to lower its overall viscosity and to reduce the specific gravity of the oil phase to less than about 0.92. The diluted emulsions are subjected to flashing at emulsion-breaking conditions after which the oil is recovered from the various streams created in the flashing steps.
