Abstract
Apparatus for de-emulsification of liquids using microwave energy as radiated into an applicator section of characteristic frequency dimensions consisting of a wave guide section that has a taper applicator element of low dielectric constant material separating the wave guide section into a radiation input void end and a larger volume liquid-filled output end; whereby emulsion under pressure is input to the wave guide section output end adjacent the applicator element to undergo radiation and convection heating and subsequent separation into constituent components.

Apparatus for emulsion separation, comprising:
- a microwave energy source of pre-selected frequency;
- a wave guide section of selected length dimensioned in accordance with the wavelength of said microwave frequency, and having first and second ends with said microwave energy input at the first end;
- an impedance matching member for increasing the microwave energy power transfer, said member being secured across said wave guide section in liquid-tight affixture to divide the wave guide section into a lesser volume space adjacent the first end and a greater volume space adjacent the second end;
- means for flowing emulsion liquid into said greater volume space adjacent said impedance matching member to receive microwave heating;
- and
- second means for flowing microwave treated emulsion liquid out of the second end for liquid separation.
Apparatus as set forth in claim I which further includes:
- means for flowing surfactant material into said wave guide section greater volume space.
