Abstract: A separator that utilizes an arcuate inlet manifold and an arcuate baffle to increase the rate of separation for a mix of materials having different specific gravities. The separator includes an arcuate baffle that defines a separation chamber and an arcuate pipe through which a mixture of materials having specific gravities is carried into the chamber. The mixture is discharged into the separation chamber against the baffle through a series of openings disposed along the perimeter of the pipe. The baffle, pipe and openings are configured relative to one another such that mixture is discharged against the baffle at an oblique angle. In preferred versions of the invention, mixture is discharged slanting up, slanting to the side or slanting up and to the side against the baffle at an angle of 18 to 24 (most preferably at about 22°).

Abstract: An apparatus and method for separating a mixture of fluids having different specific gravities, such as oil and water. The method comprises separating the mixture into multiple streams and discharging the multiple streams into a vessel below the surface of the water and directing the multiple streams against a baffle plate having a vertical surface inside the vessel, thereby increasing the rate at which the fluids would otherwise separate. Another aspect of the invention provides a separator that comprises a vessel, a baffle plate having a vertical surface inside the vessel, an inlet means for delivering the mixture to the vessel, a distribution means connected to the inlet means for separating the mixture into multiple streams and discharging the multiple streams below the surface of the heavier fluid, typically water, and against the baffle plate, thereby increasing the rate at which the fluids separate.
