Abstract
An electrostatic coalescer includes an outer wall defining a flow path for receiving a process fluid. A plurality of electrode plates is disposed within the flow path. A controller includes an inductor and a signal generator. The inductor is coupled in parallel with the plurality of electrode plates. The inductor and the plurality of electrode plates define a resonant circuit. The signal generator is coupled to the plurality of electrode plates and operable to apply an alternating current signal to the plurality of electrode plates at a frequency corresponding to a resonant frequency of the resonant circuit in the presence of the process fluid. The signal generator varies the frequency of the alternating current signal based on a positive feedback signal received from the resonant circuit to maintain resonance.
