Abstract: A method and apparatus for removing solid particles from a three-phase stream that utilizes a separation vessel comprising a vapor-liquid separation zone and an overlying vapor-solid separation zone. The vapor-solid separation zone can comprise a solids flow inhibiting structure operable to remove at least a portion of the solid particles in the vapor stream. In one embodiment, the solids flow inhibiting structure comprises at least one packed section and/or at least one spray nozzle operable to wet at least a portion of the packing. In another embodiment, the cross-sectional flow area of the vapor-solid separation zone can be smaller than the cross-sectional flow area of the vapor-liquid separation zone.
