Abstract: The method of operating rotating separator apparatus, to which fluid, including gas and liquids is supplied in a fluid jet via a nozzle, which includes separating the liquids from the gas in the stream, at a first zone within the rotating apparatus, and separating the liquids into liquids of differing density at a second zone within the apparatus. The separated liquids are removed via two open weirs which isolate the liquids in the separating zones from the shear forces from scoops within the weir passages. Longitudinal ribs may be provided for structural support, coalescence promotion and fluid recirculation inhibition.

Abstract: In a rotary turbine having inlets for mixtures of gas and liquid, and a rotary shaft, the combination comprising a separator to receive the mixture of gas and liquid, and to separate the mixture into a stream of gas and a stream of liquid; first structure to receive the stream of gas for generating torque exerted on the shaft; the separator including a rotating surface to receive the stream of liquid to form a liquid layer, and for generating torque exerted on the shaft; there being generally radial outflow passages for the separated liquid stream, and liquid nozzles terminating liquid outflow passages to pass the liquid stream and to convert the induced pressures of the radial outflow of the liquid to velocity of liquid jets, and to convert the reaction forces of the liquid jets to shaft power. Gas nozzles may be provided to receive the separated gas stream which is centrifugally pressurized and expanded through the gas nozzles to produce gas jets directed to produce torque acting on the shaft.
