A modular separating unit for separating a liquid from a gas-liquid mixture, comprising an annular riser tube, a hub coaxial with and located within the riser tube, four curved blades mounted between the hub and the riser tube, an annular downcomer tube surrounding the riser tube, and an orifice ring having an outer diameter smaller than the inner diameter of the riser tube and located adjacent the outlet end of the riser tube. The leading edge and leading surface of each blade, which are disposed adjacent the inlet end of the riser tube, are contained in a plane parallel to the initial direction of flow of the gas-liquid mixture. The trailing edge and trailing surface of each blade are contained in a plane which is at an angle of approximately 37°to a plane perpendicular to the axis of the hub. The projections of the leading edge of one blade and the trailing edge of an adjacent blade onto a plane perpendicular to the axis of the hub form an angle of approximately 22.5°.

A modular separating unit for separating a liquid from a gas-liquid mixture, comprising: an annular riser tube having an inlet end and an outlet end, said riser tube being perforated by parallel rows of spaced-apart holes adjacent said outlet end; a hub having upper and lower ends, an axis, and a cylindrical portion between said upper and lower ends coaxial with said riser tube and located therewithin; a plurality of blades mounted between said cylindrical portion of said hub and said riser tube below the holes in said riser tube, said blades being spaced at substantially equal intervals about the axis of said hub, each of said blades having a leading edge and a trailing edge, a leading surface adjacent said leading edge, a trailing surface adjacent said trailing edge, and a transition surface intermediate said leading and trailing edge surfaces, said leading edge and said leading surface being disposed substantially adjacent said inlet end of said riser tube and contained in a plane parallel to the flow direction of the gas-liquid mixture, said trailing edge and said trailing surface being contained in a plane which is at an angle of approximately 37°to a plane perpendicular to the axis of said hub, the projections of said leading edge of one of said blades and said trailing edge of an adjacent one of said blades onto a plane perpendicular to the axis of said hub forming an angle of approximately 22.5°therebetween; an orifice ring coaxial with and adjacent to said outlet end of said riser tube, the outer diameter of said orifice ring being smaller than the inner diameter of said riser tube; and an annular downcomer tube coaxial with and surrounding said riser tube, the inner diameter of said downcomer tube being greater than the outer diameter of said riser tube.
