Abstract
A method of controlling a demulsifier dosage to an AC/DC modulated coalescer is described. The method includes monitoring a characteristic of an electric current drawn by an electrical component of the AC/DC modulated coalescer, determining if the characteristic of the electric current lies outside a predetermined stable range, and increasing the demulsifier dosage if the characteristic of the electric current lies outside the predetermined stable range. A system for controlling a demulsifier dosage to an AC/DC modulated coalescer with an adjustable dosing mixing valve is also described. The system includes a current sensor arranged to monitor an electric current drawn by an electrical component of the AC/DC modulated coalescer, and a processor configured to determine if a characteristic of the electric current lies outside a predetermined stable range. Furthermore, the system is configured to increase the demulsifier dosage if the characteristic of the electric current lies outside the predetermined stable range.
