Gas well discharge velocity dissipator
First Claim
1. Device for dissipating a high pressure stream of gas and liquid conducted for a well through a discharge line for release to atmospheric pressure, said device mounted at the end of said line and locatable in a liquid containment enclosure, said device comprising:
- (a) open-bottomed hood mountable in said enclosure with the hood bottom spaced from the bottom of said enclosure and said hood having a front wall, an opposing rear wall and a downwardly sloped mid wall;
(b) conduit means mounted through said front wall and connected to said discharge line for discharging said stream towards the rear wall of said hood;
(c) first dissipator tube lying with its axis generally perpendicular to the rear wall of said hood and having a front wall connected to said conduit for conducting said stream into said first tube, the tubular wall of said first tube having a plurality of apertures therein and the diameter of said first tube being larger than the diameter of said conduit;
(d) first grate affixed within the rearward portion of said first tube and having a multitude of stream-passing apertures therein,(e) second dissipator tube having a diameter significantly larger than the diameter of said first tube and mounted coaxially with said first tube with the open rear end of said first tube disposed at the open front end of said second tube, and the open rear end of said second tube spaced from and directly opposite the rear wall of said hood, and the wall of said second tube having a plurality of apertures therein; and
(f) second grate affixed within the rearward portion of said second tube, and having a multitude of stream-passing apertures therein.

Abstract
Provided is a device for dissipating, safely and in an environmentally sound manner, a high pressure fluid discharge from a gas well. The device is locatable in an earthen pit and connectable to the end of a discharge conduit. There is an open-bottomed hood having a front wall, a rear wall and curved side and upper wall, with the well discharge conduit connecting through the front wall. Mounted within the hood is a first dissipator tube having a perforated wall and a significantly larger diameter than the discharge conduit, and including a front end connected to the discharge conduit. A deflector plate, having a multitude of perforations, is mounted across this first tube near its open rear end. A second, open-ended dissipator tube has a larger diameter than the first dissipator tube, and an array of apertures in its lower wall. It is mounted co-axially with the first dissipator tube with its front end adjacent the rear end of the first tube, and its rear end adjacent to and spaced from the rear wall of the hood. The second dissipator tube also mounts a perforated deflector plate near its rear portion, along with a vertically extending member for deflecting a stream it intercepts into two diverging portions.
