Abstract:
A method is described for breaking a water-in-crude
oil emulsion. A crude oil feedstock is tangentially
injected into the upper portion of a vortex chamber
operating on the vortex principle with the emulsion
rotating within the chamber and the velocity of the
emulsion increasing toward the center of the vortex
whereby concentric layers of emulsion having different
tangential velocities apply shear stresses to the dis-
persed water in the crude oil causing the interfacial
film between the water and the oil to rupture. This
enables chemical demulsifiers, added prior to the vortex
operation, to act more quickly and efficiently. There-
after, the dewatering of the crude oil is easily
accomplished by usual methods.
