International Classification:

B01D 17/025

US Classification:

210182, 210202, 2102212, 210243, 210255, 2105121, 210519, 210521, 2105321, 210539, 210540

Abstract:

A fluid treatment tank for use in a well fluid processing system. The tank is divided into at least three compartments, including an oil treatment compartment for receiving oil from a separator vessel of the well fluid processing system so as to allow stabilization and/or final separation and treatment of the oil, a reject treatment compartment for receiving reject fluid from one or more water treatment units of the well fluid processing system so as to allow gravitational separation of heavier and lighter components of the reject fluid, and a water treatment compartment for receiving de-oiled water from one or more water treatment units of the well fluid processing system so as to allow degassing and/or final separation of the water. Also, a well fluid processing system including such a fluid treatment tank.

Abstract:

A separator apparatus for separating immiscible fluid components of different specific gravities. A body includes an internal flow channel for a mixture of fluid components to be separated. A rotation generating device brings the fluid mixture to rotate about the longitudinal axis of the flow channel. An extraction device withdraws a central part of the rotating fluid mixture flowing through the flow channel. A bubble introducer introduces micro-sized gas bubbles into the fluid mixture so as to thereby enhance the separation of the fluid components. Also a method for separating immiscible fluid components of different specific gravities.
