Deoiling Hydrocyclones

Deoiler hydrocyclone based process systems, are the most cost-effective solution for tough produced water treatment applications. Located directly downstream of the water outlet of the production separator, and upstream of the water level control valve, these systems operate in a proportional "pressure ratio" control manner.

Deoiler hydrocyclones are pressure drop dependant, where fluids are directed into the deoiler tube causing the fluids to spin under a centrifugal force. These strong forces cause the two immiscible liquids (oil and water) to separate. The heavier water phase is forced outward toward the cyclone wall, and the lighter oil phase migrates toward the center core.

By accurately controlling the pressures across the hydrocyclone, the water phase is sent in one direction to the underflow, and the oil phase is sent in the opposite direction to the overflow. The process is a simple and effective separator, with a 2-3 second retention time, and no moving parts.
