Abstract (en)

A secondary separator vane design is used in an arrangement for separating a gas and liquid mixture. The arrangement has a vessel with an inlet (12) for entry of the gas and liquid mixture and an outlet (20) for exit of a separated gas, a primary centrifugal separator (30) in the vessel for centrifugally separating the gas from the mixture and a secondary centrifugal separator (50) in the vessel for further centrifugally separating the gas from the mixture. The secondary separator (50) has an enclosure (60) with an annular gas/liquid separator space (62). An outer circumferential inlet (64) and an inner circular outlet (66) communicate with the separator space (62) and a plurality of fluid directing vanes (56) are circumference spaced around the separator space (62). Each vane (56) is curved in the same direction of curvature from the inlet (64) to the outlet (66) to improve fluid flow. <IMAGE> <IMAGE>
