  • Patent number: 4299690
    Abstract: A process for recovering oil from oil-in-water petroleum emulsions stabilized with clay and/or other solids by subjecting them to the action of an optimum amount of non-ionic, water-soluble, aryl sulfonates-oxyalkylated phenol formaldehyde resins at a pH of 7.0 to 8.0 and then adding a saturated aqueous alkali metal halide solution to the resulting mixture. The process is carried out at between about 200.degree. F. and 240.degree. F. and the mixture is allowed to stand in the quiescent state for a period of about 1 to about 10 hours to allow the halide solution to increase the specific gravity of the resulting aqueous phase by at least 0.02 thereby causing the bitumen to float and facilitating recovery of the oil.
