Document Type and Number:
WIPO Patent Application WO/2018/204821
Kind Code:
A3
Abstract:
An apparatus for separating a fluid having a lighter specific gravity from a fluid having a heavier specific gravity and for separating fluids having lighter specific gravity from fluids having a heavier specific gravity includes an electric motor including an annular stator and a rotor having a rotor shaft having a hollow interior defining a rotatable drum having a drum rotational axis, the rotor passing through the stator and rotatably mounted on shaft mounting structure; a fluid passage structure for receiving fluids and solids of a mixture stream to be separated having a longitudinal axis, the fluid passage structure including a the rotatable drum and an impeller contained within the rotatable drum for separating with centrifugal force the constituents of the stream into radially arrayed layers of progressively increasing specific gravity.
