ABSTRACT:
A system is disclosed for preventing oil droplet size reduction when introducing an oil/water stream into an oil-from-water separation unit. The system includes a conduit extending from a source of the oil/water stream to an inlet of the oil-from-water separation unit, which can be one or more hydrocyclone separators, centrifuges, settling tanks and the like. A throttling device is operatively connected to the conduit for regulating the quantity of the oil/water stream passing therethrough. The throttling device eliminates the shearing of the fluid, thereby preventing oil droplet size reduction. The throttling device can include a progressive cavity motor with a rotation control mechanism connected to the rotor of the motor to control the rpm of the rotor, and thus the quantity and pressure of the fluid passing therethrough.
