A method suitable for coalescing at least one emulsion containing components of different electrical properties, conveying the emulsion through at least one tube of electrically insulating material while being heated and subjected to an electric field. A coalescing apparatus may comprise a casing 20 with an inner chamber 21 for accommodating insulating fluid and one or several tubes 24 of electrically insulating material extending through the casing and the inner chamber. Each tube may form a flow channel for emulsion to be treated. A set of electrodes 27a, 27b may be mounted in said chamber, each tube being allotted at least one pair of electrodes of said set. A voltage source means 30 may be provided for applying mutually different electric potentials to the electrodes of each electrode pair so as to form an electric field between them and thereby an electric field inside the respective tube. A heating device 40 may be provided to heat the insulating fluid so as to allow the insulating fluid to transfer heat to emulsion flowing through said tubes and thereby raise the temperature thereof. The coalescing apparatus may form part of an emulsion treatment system. |
