A separator vessel has inlet, fluid outlet, and sand outlet ports. Each of the fluid and sand outlet ports are spaced below the inlet port. The separator has an enclosure between the inlet and fluid outlet ports. The enclosure redirects the fluid stream and defines an inner cavity above a lower edge of the enclosure, the lower edge defining a liquid flow area. The separator has one or more vanes extending along an outer surface of the enclosure which redirect the fluid stream along a curved flow path as the fluid stream flows toward the lower edge, and a plurality of apertures adjacent to the vanes, the apertures permitting fluid flow into the inner cavity of the enclosure. The fluid outlet port is disposed within the inner cavity above the lower edge of the enclosure and below one or more apertures.
