Electrostatic coalescer and method for electrostatic coalescence

A device for electrostatic coalescence of liquid particles in a flowing fluid mixture, comprising:

• an outer tube having a wall, a feed opening located at a front side of the outer tube, a discharge opening located on an opposite side of the outer tube, and an intermediate discharge opening located between the feed opening and the discharge opening;
• power means for providing a current;
• and
• at least two electrodes located inside the outer tube electrically connected to the power means;
• wherein the device also comprises a least one arrangement with flow guide vanes arranged in the outer tube, positioned in between the feed opening and the discharge opening located on the opposite side of the outer tube, for reducing the turbulence or for imparting a rotating movement to the fluid mixture flowing through the outer tube, and
• a co-centric inner tube arranged in the outer tube and located, as seen in the direction of the fluid flow, behind the at least one arrangement with flow aide vanes, wherein the co-centric inner tube has a diameter less than the diameter of the outer tube and is positioned to provide a space between the inner tube and the wall of the outer tube, wherein the intermediate discharge opening connects to the space between the co-centric inner tube and the wall of the outer tube.
