ABSTRACT:
An oil and water mixture containing a dispersed phase and a continuous phase is passed for treatment through a rotating horizontal tumbler containing free bodies and a hydrocarbon diluent for the purpose of facilitating subsequent separation of the phases of the mixture. The free bodies tumbling with the mixture in the drum have affinity for the dispersed phase particles, and the hydrocarbon diluent reduces the viscosity of the oil phase thereby causing an increase in the particle size of the dispersed phase of the mixture. Some mixtures that may be treated include effluent streams from a hot-water oil sands extraction plant, oil-in-water emulsions from processes that use enhanced oil well recovery and bitumen froth.
