Combosep™ System

Our patented Combosep (COMBination Of SEParators) is typically comprised of a vertical and horizontal flotation system, mounted on a common skid, complete with interconnect piping.

For extremely large flow rates, the vertical unit (Spinsep or Cyclosep) can be packaged on a skid separate from the horizontal Veirsep unit. This sophisticated design precludes the need for a gravity separator or skimmer upstream of the flotation system.

The Process
The vertical Spinsep or Cyclosep unit is the primary separator system of the Combosep system. The Cyclosep separator, if used in this application, would include a built-in hydrocyclone to separate the solids and oil from the produced water. The oil is processed within the cyclone to exit the top of the cyclone with the gas vapor. The cleaner water, with the solids, exits the bottom of the cyclone where they are separated and removed from the vessel.

The final polishing vessel of the Combosep would include a Veirsep flotation system that removes the remaining oil to achieve discharge limits. The unit is comprised of seven separation chambers, has no internal moving parts and can be equipped with either DGF or eductor technology to provide gas bubbles that attach and lift the oil to the surface where it is skimmed into the oil compartment.

Design Options

• ASME Code or non-code vessel construction
• DGF, eductor or sparge tube flotation design
• Coalescing pack constructed of Polypropylene or Stainless Steel (Combosep-Plus)
• Customer determines controls, valve configuration and safety controls

The Combosep system is designed to replace the traditional use of separators, skimmers and flotation polishing systems. It can replace an entire produced water treatment system with two vessels, a vertical skimmer and horizontal flotation unit. The Combosep system has the ability to replace multiple treatment vessels due to flotation capabilities in both Combosep vessels. This unit is offered in multiple configurations:

SPINSEP-P/VEIRSEP
CYCLOSEP-P/VEIRSEP
SPINSEP-P/SPINSEP
