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.

ABSTRACT: Liquid-liquid hydro cyclone separating method is a modern oil contaminated sewage disposal method. Now the special function of pressure drop ratio in liquid-liquid separation, e.g. oil-water separation, is introduced by analyzing amounts of '' indoor experiment data.

Produced Water Primary Treatment Options — GATE, Inc ...

Hydrocyclones need a minimum pressure drop of around 100 psi to operate effectively, though this may be lower depending on the size of the hydrocyclone. Pumps may be required upstream of the hydrocyclones in order to increase the pressure drop and get effective separation; however, pumps tend to shear oil droplets. For this purpose, disc pumps or low shear, progressive cavity pumps should …
