ABSTRACT:
A process for recovering oil from either water-bituminous petroleum emulsions or from crude petroleum emulsions having a pH of 10 or less by adding thereto an optimum amount of non-ionic, water soluble polyethylene oxide polymers at a pH of 10 or less, and separating the oil from water. To resolve bituminous petroleum emulsions, the process is carried out at between 150.degree. F and 210.degree. F and a diluent is added to reduce the petroleum viscosity. The minimum effective concentration of the polymers used decreases as their molecular weight increases.
In a modification of the process, an effective amount of an alkaline earth metal halide such as calcium chloride is added to improve coagulation and separation of any clay present.
