A method for removing particulates from a fluid, the method including the steps of: producing a laminar flow of the fluid through a single-flow passageway defined by an interior surface of an outer rotor of a centrifuge; and imparting centrifugal force on the fluid in a direction orthogonal to a direction of the flow of the fluid to capture the particulates from the fluid. The method may further comprise rotation of the centrifuge at a speed of 5,000 to 15,000 revolutions per minute. The method may also or alternatively comprise locating the interior surface between 3 and 5 inches from an axis of rotation of the centrifuge.

Method for removing particulates from a fluid

A centrifuge is employed to continuously remove particulates from a fluid. In one embodiment, the centrifuge removes small particles of soot from lubricating oil of diesel engines. The fluid is introduced into the centrifuge through a distribution rotor so that vortexes are not propagated in the fluid. Laminar flow of the fluid down the sides of the outer rotor may contribute to the soot-removal effectiveness of the centrifuge.
