Abstract: The invention is a high pressure trap for removing particles from a flow stream of a high pressure well that maintains the full pressure of the high pressure well, wherein the trap has an inlet port connected to a Christmas tree, a chamber with a top flange, a bottom flange, and a side wall connecting the top flange and the bottom flange in fluid communication with a choke manifold, a dump outlet in communication with the bottom reservoir and connected to the bottom flange, a dump outlet controller for opening and closing the dump outlet, and a tube disposed between the bottom reservoir and the side outlet, wherein the tube is mounted within the chamber to the top flange without contacting the side wall, thereby the velocity of the flow stream is changed as the flow stream is passed from the tube into the chamber.

Abstract: A hydraulic choke for a flow stream from a well with large diameter particulate matter of a finite amount includes an inlet with a defined inlet flow area and a chamber with a defined chamber flow area. The inlet flow area is about ⅓ the size of the chamber flow area. The choke further includes a gate in the chamber surrounded by a housing separated from the chamber wall, a piston for engaging the gate against a seat, a studded outlet in communication with the chamber in the same plane as the inlet, and a studded solids removal outlet in communication with the chamber. The studded solids removal outlet is oriented approximately 90 degrees from the inlet position to permit the large diameter particulate matter to fall from the flow stream and into a solids receptacle for collecting the large diameter particulates matter. The solids receptacle is in communication with the studded solids removal outlet.

Abstract: A method for removing particles Particles are removed from a high pressure flow stream entails by flowing the high pressure flow stream into an inlet of a high pressure trap and flowing the flow stream from the inlet into a tube in the high pressure trap. The tube is adapted to accelerate the flow stream. The flow stream leaves the tube and de-accelerates as the stream flows into a chamber. The method continues by contacting the The flow stream with contacts a plate wound helically around an outside surface of the tube. The plate creates a cyclonic effect with in the flow stream to remove particles from the flow stream. The particles are collected in a reservoir. The remaining Remaining particles are removed by flowing the flow stream towards a side outlet over the plate. The methods end by collecting the The remaining particles are collected in a the reservoir forming collected particles and dumping the . The collected particles are periodically dumped from the reservoir.
