DEMULSIFYING PETROLEUM EMULSIONS WITH ARYL SULFONATES-OXYALKYLATED PHENOLFORMALDEHYDE RESINS AND ALKALI METAL HALIDES (D#51,500-TexEx-52-F) Brian W. Allan ABSTRACT OF THE DISCLOSURE 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- oxylakylated 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°F and 240°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.
