Patent ID: 8062400

Claim:
An apparatus for separating a fluid, comprising: a shaft rotatable about a central axis; a rotary separator drum coupled to the shaft and configured to rotate therewith, the rotary separator drum comprising: an inner drum member having inner and outer circumferential surfaces and being disposed about the shaft such that a first flow passage is defined between the inner circumferential surface of the inner drum member and the shaft, the inner circumferential surface of the inner drum member being configured to separate liquids from a fluid flow contacting the inner circumferential surface of the inner drum member; and an outer drum member having inner and outer circumferential surfaces and being disposed about the inner drum member such that a second flow passage is defined between the inner circumferential surface of the outer drum member and the other circumferential surface of the inner drum member, the second flow passage being coaxial with the first flow passage, the inner circumferential surface of the outer drum member being configured to separate liquids from a fluid flow contacting the outer circumferential surface of the other drum member; and a static member in fluid communication with the rotary separator drum, the static member including a separation surface located upstream from the rotary separator drum and extending circumferentially about and spaced radially outward from the outer drum member.
