Abstract
A method of separating oil and water in a flow-stream through a gravity settling vessel () in which the flow-stream () separates into a lower water layer () and an upper oil layer (), includes feeding an off-take stream () of the oil layer and/or an emulsion layer () that forms between the oil layer and the water layer through a compact electrostatic coalescer (CEC) () that has electrically isolated electrodes. The CEC coalesces water droplets in the off-take stream, and the coalesced off-take stream is then returned to the settling vessel. An associated separator apparatus for comprises: a gravity settling vessel (); a CEC () including electrically isolated electrodes; a coalescer feed line () configured to provide an off-take stream of an oil phase and/or an emulsion layer from the settling vessel to the CEC; and a return line () from the CEC for returning the off-take stream to the settling vessel.
