Abstract
A microwave applicator to effectively break hydrocarbon and water emulsions with radio frequency energy. A stream of hydrocarbon and water emulsion is pumped into a multimode resonant reentrant microwave cavity. Dual opposing emulsion flow chambers with a centrally supplied microwave waveguide form a double ended resonant chamber with multiple RF energy reflections to effectively treat the flowing emulsion. The emulsified feedstock enters into the bottoms of both flow chambers and exits to a centrifuge or storage for separation.

Apparatus for breaking an oil and water emulsion feedstock into oil and water streams with a source of radio frequency waves which comprises:
- a radio frequency wave guide for receiving radio frequency waves;
- a process chamber adjacent the waveguide configured to permit the emulsion feedstock to move therethrough and to expose the emulsion feedstock to radio frequency waves;
- a radio frequency transparent window between the waveguide and process chamber to allow passage of radio frequency energy into the process chamber;
- and
- a deflector located in the waveguide oriented to deflect radio frequency waves to the radio frequency transparent window and into the process chamber.
A system for breaking oil and water emulsion feedstock using radio frequency energy which comprises:
- a source of radio frequency energy;
- a waveguide for conveying the energy for use to treat the emulsion feedstock;
- a feedstock process chamber having at least one inlet and at least one outlet oriented adjacent the waveguide;
- a radio frequency transparent window between the process chamber and the waveguide to allow passage of radio frequency energy from the waveguide into the process chamber;
- a deflector of radio frequency energy oriented in the waveguide to direct the radio frequency energy from the waveguide through the window and into the process chamber;
- and
- a pump for passing the emulsion feedstock through at variable rates responsive to the temperature rise of the emulsion feedstock as it passes through the process chamber receiving radio frequency.
