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.
