Abstract
Abstract A fluid separator includes a gravity separation chamber ( 4 ) including an inlet duct ( 2 ) for a mixture of gas and liquid, and a cyclonic inlet diverter (D) located within the gravity separation chamber. The cyclonic inlet diverter (D) includes a cyclonic inlet chamber ( 18 ) connected to receive a mixture of gas and liquid from the inlet duct ( 2 ), a cyclonic separation chamber ( 20 ), a gas outlet ( 22 ) at an upper end of the cyclonic separation chamber and a liquid outlet ( 24 ) at a lower end of the cyclonic separation chamber. The cyclonic inlet chamber ( 18 ) has an involute configuration.
