Abstract

A desanding system has an elongated vessel that is tilted at a non-zero inclination angle. A fluid inlet at the vessel's upper end discharges a gas stream having entrained liquids and particulates and a fluid outlet into a freeboard portion formed adjacent an upper portion of the vessel above a gas/liquid interface formed below the fluid outlet. A belly storage portion is formed below the interface. The freeboard portion of the vessel has a freeboard cross-sectional area that diminishes along the interface from the fluid inlet to a fluid outlet spaced away from and lower than the fluid inlet. The cross-sectional are of the freeboard portion causes precipitation of the entrained liquids and particulates therefrom and collect in the belly portion of the vessel. A desanded gas stream, being free of a substantial portion of the particulates is removed from the vessel through the fluid outlet.
