Hydrocyclone based process systems, are the most cost-effective solution for
tough produced water treatment clean up. Located directly downstream on 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
By accurately controlling the pressures across the hydrocyclone, the water phase
is sent in one direction, downward, to the underflow, and the oil phase is sent in
the opposite direction, upward, to the overflow. The process is a simple and
effective separator, with a 2-3 second retention time, and no moving parts.
