OTSO Free Water Knockout (FWKO) systems automatically remove free water from your crude oil ahead of the heating or treating system. These FWKOs accommodate the requirements of wells or leases that lack provision for handling free water. Many treating systems are often overtaxed by the continual increase in volume of free water produced with the oil or emulsion. In such systems, the total production of the wells is handled through the heating system, and increased production of free water is to be expected. The volume will not only exceed the heating unit’s capacity, it will also result in waste of fuel to unnecessarily heat the excess or increased water. Our FWKO system is designed to address these problems and optimized performance.
