NOVELTY - A centrifuge separator comprises: main inlet pipe (22) having an inlet opening for receiving untreated fluid; inline rotor assembly (30); first conical shaped chamber (42) having first side outlet; pipe member; second conical shaped chamber (56) having second side outlet; and collection pipe. The rotor assembly comprises internally located impeller (32) in fluid communication with lower end of first chamber; drive shaft (34) operatively associated with the impeller; gear box (36) operatively associated with the shaft; and motor operatively associated with the gear box.    USE - As a centrifuge separator for separating a composition comprising particles having different specific gravities (claimed), particularly for separating oil from water, such as an oil spill by a tanker out at sea.    ADVANTAGE - The present device separates substances of different specific gravities by induced vortex separation. The inline impeller exerts the centrifugal force on the flowing fluid particles. The present centrifugal separator creates different zones of the different specific gravity fluids by entering the centripetal force on the particles. The diameter of rotation of the particle is derived by the rotational speed and the mass of the particle in the fluid, causing the heavier particles to rotate to the outside, as compared to the lighter particles, which permits the various particles to be substantially divides so that the various particles can be collected at designated collection points for the centrifuge separator.    DETAILED DESCRIPTION - A centrifuge separator, comprises: a main inlet pipe (22) having an inlet opening for receiving an untreated fluid; an inline rotor assembly (30) in fluid communication with the main inlet pipe; a first conical shaped chamber (42) positioned above the inline rotor assembly and in fluid communication with it, and having a first side outlet; a pipe member in fluid communication with the first chamber; a second conical shaped chamber (56) positioned at a top end of the pipe member and in fluid communication with the pipe member, and having a second side outlet; and a collection pipe at least substantially centrally located with respect to the second chamber and pipe member, and is in fluid communication with the pipe member. The centrifuge separator further comprises: a gas inlet member in communication with an internal area of the main inlet pipe; and a static mixer (26) disposed with the main inlet pipe for mixing gas receiving through the gas inlet member with the untreated fluid, the gas inlet member in communication with the internal area of the main inlet pipe intermediate of the static mixer and the inlet opening of the main inlet pipe. The inline rotor assembly comprises: an internally located impeller (32) in fluid communication with a lower end of the first chamber; a drive shaft (34) operatively associated with the impeller; a gear box (36) operatively associated with the drive shaft; and a motor operatively associated with the gear box. A gas or gases injected through the gas inlet member. An INDEPENDENT CLAIM is included for separating a composition comprising particles having different specific gravities, involving receiving at an inlet of a pipeline a source of fluid comprising particles having different specific gravities from each other; causing the source of fluid to spin within the pipeline from a centrifugal force generated by an inline rotor assembly which in turn causes the higher specific gravity particles of the composition to spin to the outside with respect to the other particles of the composition; exiting the higher specific gravity particles out of the pipeline; and permitting the remaining particles of the composition to continue to travel within the pipeline.
