Abstract

An electrically energized device for coalescing a first conductive fluid emulsified in a second fluid. A tube member has at least one fluid inlet and at least one fluid outlet. The tube member defines a flow channel for an emulsion of the first and second fluid from its inlet side to its outlet side and includes at least one electrically insulating wall portion. An interacting pair of a first and a second electrode is separated from the first and second fluid by at least one insulating wall portion of the tube member. The electrodes are supplied with a voltage for the purpose of subjecting the first and second fluid flowing through the flow channel to an electrostatic field. At least one passive center electrode is made of a conducting material and is arranged in the channel and electrically insulated from the first and second electrode.
