TYPHONIX LOW SHEAR PUMPS

By using turbulence more constructively, Typhonix Low Shear Pumps reduce droplet breakup and increase droplet growth while pumping produced water. Since 2011, Typhonix has been developing low shear centrifugal pumps specially designed for produced water applications.

LOW SHEAR PUMPS

Conventional centrifugal pumps are known to break oil droplets while pumping produced water. The consequence is that the efficiency of the 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.

Typhonix has together with the oil companies Vår Energi, ConocoPhillips, Equinor, Neptune Energy and the Research Council of Norway, developed separation friendly centrifugal produced water pumps. The low shear 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.

Produced water pump case study

A case study based on an actual produced water pump application has been performed to evaluate the operational and economic benefits of low shear and coalescing produced water pump types, compared to that of conventional produced water pumps.

Low shear pump selection considerations

This article is intended to give a compact overview of some of the main factors involved in the pump selection. References to relevant articles are added for further reading. The topics discussed are; evaluation of the pump types, a discussion on the level of low shear that is acceptable, and evaluation of pump turndown solutions.

COSTUMER VALUE AND USER BENEFITS

  • Typhonix Low Shear Pumps improve the efficiency of produced water treatment equipment.
  • Typhonix Low Shear Pumps have a robust design in accordance with API 610, and therefore have a lower OPEX and MTBF compared to many positive displacement pumps.
  • Typhonix Low Shear Pumps normally do not require any blocked outlet protection (e.g., a PSV), contrary to that of positive displacement pump.
  • Typhonix Low Shear Pumps improve the separation efficiency without resorting to chemicals or additional treatment equipment, reducing reduced oil and chemical discharges to the sea.
  • Typhonix Low Shear Pumps contribute to a cost-effective and environmentally friendly separation process.
  • Typhonix Low Shear Pumps contribute to reduced size and footprint of greenfield process plants by increased separation efficiency.
