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.
