Abstract
A fluid mixture containing a heavy component and a light component is separated by feeding the fluid mixture into a vessel. The vessel includes a light component outlet regulated by a first valve and a heavy component outlet regulated by a second valve. The vessel is rotated about a rotational axis extending through the vessel as the liquid-liquid mixture is feed into the chamber such that the heavy component collects toward at least a portion of the peripheral wall of the vessel radially outward from the rotational axis and the lighter component collects toward the rotational axis. The first valve is set such that the light component exits therethrough at a first pressure. The second valve is set such that the heavy component exits therethrough at a second pressure, the second pressure being different than the first pressure.
