Chemical emulsions in produced and slop water can be difficult and costly to separate. In an offshore environment the challenges multiply as time, footprint and manpower are restricted. TwinZapp consists of a single skid a with three stage process. Stage 1: Electro Oxidation (Elox), using multiple pairs of electrodes. Stage 2: Separation, where the emulsion is broken. Stage 3: Polishing, where further hydrocarbon removal occurs and typically 5 to 10 ppm is achieved through either a Media Filter with glass bead or a Duplex Cartridge Unit.
