Abstract:
1. A desanding vessel for removal of particulates from a fluid stream containing particulates, comprising: a fluid inlet adjacent a first end of the vessel and adapted for receiving the fluid stream, the fluid inlet discharging the fluid stream at an inlet velocity into a freeboard portion at a top of the vessel, the fluid stream in the freeboard portion having an elutriation velocity less than the inlet velocity and such that contained particulates have a fall trajectory; a fluid outlet from the vessel, the outlet being spaced horizontally from the inlet; and a flow barrier depending from the top of the vessel and having a lower edge so as to direct the fluid stream below the barrier before discharge from the outlet port for maintaining the freeboard portion above the lower edge and forming a belly storage portion below the lower edge, the maximum depth of the belly storage portion being set by said lower edge the flow barrier being positioned between the fluid inlet and fluid outlet and the flow barrier being spaced from the fluid inlet so as to enable the fall trajectory of a substantial amount of the particulates to intersect the belly portion so as accumulate particulates in the belly portion prior to the flow barrier prior to the flow barrier wherein the fluid stream at the fluid outlet is substantially free of particulates.
