Abstract
Official abstract text for this publication.
Embodiments described herein provide a method of separating a liquid mixture, comprising providing a liquid mixture to a separator, electrically coupling a power circuit to the liquid mixture inside the separator, applying a time-varying voltage to the power circuit, detecting a phase angle in the power circuit; and controlling the phase angle by adjusting a characteristic of the time-varying voltage.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of separating a liquid mixture, comprising: providing a liquid mixture to a separator; electrically coupling a power circuit comprising a powered electrode to the liquid mixture inside the separator; applying a time-varying voltage to the powered electrode; coupling a reference electrode to the liquid mixture using an electrical conductor; detecting a phase angle in the electrical conductor; minimizing the phase angle by adjusting a characteristic of the time-varying voltage; comparing the characteristic of the first time-varying power to a standard; and adjusting an aspect of the separation process based on the comparison. 2. The method of claim 1 , wherein the time-varying voltage is a multi-frequency AC voltage. 3. The method of claim 1 , wherein the characteristic of the time-varying voltage is selected from the group consisting of frequency, amplitude, modulation, voltage gain, voltage gain modulation, and waveform. 4. The method of claim 1 , further comprising detecting a phase angle in the power circuit. 5. The method of claim 4 , further comprising comparing the phase angle of the power circuit to the phase angle of the electrical conductor. 6. The method of claim 5 , further comprising adjusting a different characteristic of the time-varying voltage based on the phase angle of the power circuit.
