A device, located in a vessel having an inlet and at least one outlet, through which a mixture of fluids flows, for promoting electrostatic coalescence of a first conductive fluid emulsified in a second fluid. The device includes a number of tubular electrostatic coalescer elements extending in the flow direction which are arranged in a matrix arranged over the cross sectional area of the vessel, and an applicator operative to apply an electrical field to the fluids flowing through the coalescer elements.

Electrostatic coalescer device and use of the device

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.

Device for coalescing a fluid

An electrically energised device for coalescing a first conductive fluid, emulsified in a second fluid, comprising a tube member ( ), having at least one fluid inlet ( ) and at least one fluid outlet ( ), the tube B member ( ) defining a flow channel ( ) for an emulsion of the first and second fluid from its inlet side to its outlet side and comprising at least one electrically insulating layer portion, the channel B ( ) having a generally circular or elliptic cross section, and an interacting pair of a first and a second electrode ( ) that are arranged outside and adjacent to the at least one insulating layer portion, that separates the electrodes ( ) from the channel ( ) and thereby from immediate contact with the emulsion, and supplied with a pulsed or alternating voltage for the purpose of subjecting the first and second fluid flowing through the flow channel to an electrostatic field. The first and second electrode ( ) are separated with a gap and extend generally in parallel in the length direction of or helically around the flow channel ( ).
