Produced Water Polishing with
EPCON CFU Technologies

Overview Library

Field-proven technologies for treating produced water

Schlumberger EPCON compact flotation unit (CFU) technologies efficiently remove oil from produced water, decreasing the oil content to below 5 ppm and enabling overboard discharge or reinjection for more efficient operations. Additionally, the technologies feature a smaller footprint and shorter retention time than traditional systems.

EPCON Dual CFU

By incorporating a secondary separation stage, the EPCON Dual CFU increases oil-in-water removal efficiency while fully degassing the clean water outlet. This enables achieving improved oil-removal separation efficiency in a 50% smaller footprint compared with traditional systems.

EPCON CFU

This robust technology reduces oil-in-water content while enhancing operational reliability and saving rig space.

Multiple advantages over conventional systems

Our EPCON CFU technologies offer numerous advantages over conventional water polishing methods, including

  • integration of standard, well-established gas flotation design with a confined swirling flow principle, producing a compact, high-performance system
  • suitability for FPSO applications, where the technologies' design suppresses the negative effects of sloshing
  • maximized simplicity, ease of control, and separation performance in minimal rig space and weight
  • improved safety by reducing harmful soluble oil pollutants.
