Chemical emulsions in produced and slop water are not easy to separate. In an offshore environment the challenges multiply as time, footprint and manpower are restricted. TwinZapp consists of a single skid with a plug and play, 2 step solution to clean emulsions to well below North Sea discharge limits at a typical rate of 30 bbl per hour. No consumables, and no specialized operators are required. The resulting overboard water contains mostly less than 5 ppm of oil.

The emulsified water is first subjected to a mild, well controlled, electrical oxidation process. Release of reactive oxygen, hydroxyl and other radicals destabilize the present surface active components. The resulting free oil along with the neutrally buoyant particles (and associated oil) as well as a sizeable fraction of the dissolved
aromatics is then removed by a fully re-generable filter at the final polishing stage. The processes are ATEX Zone II certified and mounted in a DNV certified skid. As the unit is equipped with a totally stand-alone control system, TwinZapp can under no circumstances interfere with hydrocarbon production processes.
