Patent ID: 6893558

Claim:
A high pressure trap for removing particles from a flow stream of a high pressure well and wherein the trap maintains the full pressure of the high pressure well, comprising: a. an inlet port connected to a Christmas tree; b. a chamber having a top flange connected to the inlet port and a bottom flange connected to a bottom reservoir and a side wall connecting the top flange and the bottom flange, and further wherein the side wall comprises a side outlet in fluid communication with a choke manifold; c. a dump outlet in communication with the bottom reservoir and connected to the bottom flange; d. a dump outlet controller for opening and closing the dump outlet; e. a tube disposed between the bottom reservoir and the side outlet, wherein the tube comprises i. a first end connected to the top flange; ii. a second end opening into the chamber; iii. an inside surface; iv. an outside surface; v. a plate is disposed on the outside surface and oriented in a helical arrangement around the outside surface; and vi. wherein the tube is mounted within the chamber to the top flange without contacting the side wall, and thereby the velocity of the flow stream is changed as the flow stream is passed from the tube into the chamber.
