Abstract

A system for removing gas from a stream of a mixture of gas and particulate solids. The system includes a separation vessel having an upstream end portion and a downstream cowl portion, the upstream end portion having an inlet for introducing the stream tangentially into the vessel to separate centrifugally from the stream (i) a rich portion, comprising a solids-rich mixture, proceeding along a helical path at an outer annular portion of the separation vessel to the cowl portion, and (ii) a lean portion, comprising a solids-lean mixture, proceeding along a helical path at an inner portion of the separation vessel to the cowl section, multiple helical ports through which the rich portion proceeds axially through the cowl section, without significantly losing its momentum, to be discharged axially from the separation vessel, and multiple passages between the helical ports through which the lean portion proceeds radially outwards to be discharged from the separation vessel.
