liquid hydrocyclone pressure ratio

The Logic Behind The Magic."Produce water Hydrocyclones"

2013-05-05· The hydrocyclone is operated under differential pressure ratio controller i.e the ratio of (hydrocyclone inlet pressure minus reject oil stream pressure) to ( hydrocyclone inlet pressure minus hydrocyclone water outler pressure). The DPR controller is set at adjusted value and will continuously adjust the hydrocyclone reject oil control valves to achieve the DPR set point.

Hydrocyclone Separator | Oil and Gas Separator

The PDR refers to the ratio of the pressure difference between the inlet and reject outlets and the difference from the inlet to the water outlet. A PDR of between 1.4 and 2.0 is usually desired. Performance is also affected by inlet oil droplet size, concentration of inlet oil, differential specific gravity, and inlet temperature. Temperatures greater than 80°F result in better operation.
