ABSTRACT:
Method and apparatus for treating an oil-in-water, such as a bitumen-in-water emulsion, by premixing the emulsion for a sufficient period of time to permit it to become fully intermixed with emulsion breaking diluents and other additive materials. The modified, bitumen-containing emulsion stream is circulated through a premixer. At least a part of the emulsion stream is recirculated therein to intermix with fresh incoming emulsion flow. Thereafter the now more thoroughly intermixed emulsion, together with the various diluents and additives, is in better condition to be introduced to a separator unit for affecting a quiescent separation of water from the bitumen.
