Abstract

A cyclonic de-sander for a fluid stream. The cyclonic de-sander includes a pressure vessel, with a fluid inlet configured to deliver the fluid stream into the interior volume of the pressure vessel. The fluid inlet delivers the fluid stream in an eccentric manner, thereby forming a cyclone within the interior volume. The de-sander also includes a vortex tube residing vertically within the pressure vessel. The vortex tube comprises an upper end in fluid communication with the upper end of the pressure vessel, and a lower end in fluid communication with the interior volume. Additionally, the cyclonic de-sander includes a funnel. The funnel resides within the interior volume below the fluid inlet and below the lower end of the vortex tube. The funnel comprises a frusto-conical body configured to gravitationally receive solid particles from the fluid stream and inhibit the travel of solid particles back up the pressure vessel.
