Abstract
A sand trap for use in oil and gas extraction operations includes a cylindrical vessel for receiving a high-pressure fluid stream with particulates. The vessel has a vertical longitudinal axis and a hollow cylindrical wall having upper and lower ends and an inlet opening generally perpendicular to but askew to the vessel longitudinal axis. Upper and lower caps extend from the upper and lower ends and have openings along the vessel longitudinal axis. An annular diverter has top and bottom ends and a longitudinal axis coaxial with the vessel longitudinal axis. A diverter outer wall permanently extends from an inner face of the cylindrical wall, and a diverter inner wall has an upper portion narrowing to a choke area and a lower portion flaring out from the choke area. A vent pipe extends from the upper cap opening to a location between the upper cap and the diverter top end.
