CrudeSep is a compact 4-phase separator designed to treat produced water, reducing oil content in the water to acceptable discharge levels over a wide range of flow rates and conditions. Oil in water reduction to 5 ppm (or below 10 ppm) are achievable dependent on water conditions. CrudeSep is a produced water treatment vessel operating at near atmospheric pressure. Oil recovery and solids removal is achieved by induced gas flotation and a cyclonic motion system. Produced water enters the CrudeSep vessel through tangential nozzles which are geometrically spaced to eliminate the effects of surge or slug flow. Influent fluid enters a treatment zone where continuous recycle maintains a minimal spin providing sufficient centrifugal force for immediate oil/water separation. Gas bubbles are injected with recycled water below the inlet water nozzles to maintain a continuous supply of `flotation` gas. Flotation effects and centrifugal forces will bring the oil droplets to the surface where they are subsequently skimmed to the oil bucket. CrudeSep can also be used upstream of CETCO`s Hi-Flow and CrudeSorb technologies as a primary oil separation system.
