Conventional centrifugal pumps are known to break oil droplets while pumping produced water. The consequence is that the efficiency of downstream produced water treatment processes is reduced. Often positive displacement pumps, like eccentric screw pumps are used to counteract oil droplet breaking. Drawbacks of positive displacement pumps, however, are often high maintenance requirements and limited operational window.
Typhonix has together with the oil companies ENI, ConocoPhillips, Statoil, GDF SUEZ and the Research Council of Norway, developed separation friendly centrifugal produced water pumps. The low shear/coalescing centrifugal pumps are developed for produced water applications and through extensive testing Typhonix has shown that it is possible not only to make a pump which does not break droplets, but also enlarges oil droplets during pumping. Due to the robust design in accordance with API 610 these pumps have large OPEX benefits compared to low shear positive displacement pumps.
The Typhonix pumps are manufactured by a certified API 610 pump manufacturer in Germany.
The benefits for the end user are 1) more energy efficient produced water treatment, cleaner produced water and reduced oil and chemical discharges to the sea, and 2) more energy efficient water flooding by less broken injection chemicals, improved produced water injection efficiency, increased oil production and less emissions into the air.
