ABSTRACT:
A separator for separating liquids immiscible with each other and containing solids heavier than the heavier liquid, includes a rotating conic drum into which the liquids are injected. The drum has a circumferential wall formed of two oppositely-directed conic surfaces joined at the bases at an inclination angle to form an equator; and openings are provided at the equator for the heavier liquid and the solids to pass. Preferably, the drum has a star-like cross section with the interior wall extending inward at an angle from either side of each opening. The separator can include a weir or paring disc disposed radially in the static pressure chamber at a nominal level of the heavier liquid to maintain proper pressure of the heavier fluid to prevent the lighter liquid from discharging into the static pressure chamber. Alternatively, a sensor and valve arrangement can be provided to achieve this benefit.
