EPCON Dual Compact Flotation Unit | Schlumberger


Compact flotation unit

Enhanced produced water treatment efficiency with a 50% smaller footprint

The EPCON Dual compact flotation unit (CFU) has a unique internal design that incorporates residual flotation gas in a secondary separation stage to increase oil-in-water (OIW) removal while fully degassing the clean water outlet. The compact, simple system achieves optimal water treatment in half the footprint of conventional technologies, saving rig space and streamlining operations—all with no moving parts.

Testing and simulation leads to real-world results

Computational fluid dynamics simulation, onshore pilot testing, and offshore results verification guided and validated the design of the EPCON Dual CFU. A successful field trial was performed on a Statoil installation in the Norwegian waters of the North Sea. Posttreatment outlet oil concentration was measured at 10 ppm, down from pretreatment levels in excess of 25 ppm. The results also verified 27% better separation rates compared with conventional technologies.
