US 2026/0295599 A1 · A METHOD OF OPERATING A CENTRIFUGAL SEPARATOR

Abstract

The present invention provides a method of operating a centrifugal separator. The centrifugal separator comprises a centrifuge bowl arranged to rotate around an axis of rotation and in which the separation of a liquid mixture takes place, a stationary hood which defines at least part of a surrounding space in which said centrifuge bowl is arranged, a drive member configured to rotate the centrifuge bowl around the axis of rotation. The centrifuge bowl further comprises an inlet for receiving the liquid mixture to be separated and at least one liquid outlet for discharging a separated liquid phase. The method comprises the steps of a) separating the liquid feed mixture into at least one separated liquid phase in the centrifuge bowl; b) supplying water from a collection tank to the centrifugal separator for cooling said stationary hood; c) collecting the supplied water from step b) in said collection tank after cooling said stationary hood and d) resupplying water from the collection tank to the centrifugal separator for cooling said stationary hood such that a circulation loop of water is formed between the centrifugal separator and said collection tank.
