Abstract
A vessel for use in settling particulate matter from a fluid stream is provided. Fluid is introduced to the vessel through an angled inlet, with flow into the vessel both disrupted and deflected by an inlet baffle, to redirect the fluid stream parallel to a horizontal axis of the vessel. The velocity of the fluid stream is reduced within the vessel, allowing the particulate matter to settle along the bottom of the vessel.
Claims47
A vessel for use in separation of particulate matter from a fluid stream, the vessel comprising;
- a horizontally elongated separation chamber comprising first and second ends, the chamber comprising walls defining a chamber volume;
- a chamber inlet and outlet, each providing an angular flowpath with respect to the elongated axis of the chamber, the inlet proximal to the first end of the chamber to define an inflow pathway for delivery of a fluid stream into the first end of the chamber, the outlet proximal to the second end of the chamber to define an fluid outflow pathway from the second end of the chamber, the chamber thereby providing a separation flowpath along the elongated axis of the chamber from the chamber inlet to the chamber outlet;
- one or more separation baffles depending from a bottom surface of the chamber between the inlet and the outlet to facilitate collection of particulate matter from the fluid stream along the bottom surface of the chamber;
- and
- an inlet baffle disposed within the chamber and aligned with the inflow pathway to disrupt flow of the fluid stream entering the separation chamber wherein the inlet baffle is positioned at an angle such that the surface of the baffle is aligned with both the inlet of the vessel and the downstream elongated axis of the vessel, so as to redirect the fluid stream toward the outlet.

- and
- an outlet baffle within the chamber, the outlet baffle proximal to the outlet for disrupting flow of fluid from the inlet to the outlet.

A method for use in settling particulate matter from a fluid stream, the method comprising the steps of:
- receiving a fluid stream from a fluid stream conduit, the fluid stream comprising fluid and particulate matter at a first pressure;
- introducing said fluid stream to a horizontally elongated vessel through a substantially vertically oriented inlet of the vessel, the horizontally elongated vessel further comprising a fluid outlet distal to the vertically oriented inlet of the vessel;
- operating the vessel contents at a second pressure, the second pressure lower than the first pressure to facilitate settling of particulate matter within the vessel;
- contacting the fluid stream with an inlet baffle, the baffle proximal to the inlet and oriented so as to redirect the vertical flow of the fluid stream from the inlet along the horizontal axis of the vessel;
- collecting fluid from the fluid outlet of the vessel;
- collecting settled particulate matter from the vessel by releasing the pressure inside the vessel through the use of a pressure releasing valve;
- and
- by opening a valve proximate the inlet or by opening a valve proximate the outlet and removing said particulate matter.

A method for separating particulate matter from a fluid stream, the method comprising the steps of:
- providing a separation vessel comprising:
- a horizontally elongated separation chamber, an inlet defining an inflow pathway substantially perpendicular to the elongated axis of the vessel, and a fluid outlet distal to the inlet, the outlet for discharging fluid from the vessel;
- introducing an inflow stream comprising fluid and particulate matter to the inlet;
- providing a baffle within the vessel, the baffle positioned within the inflow pathway and oriented to deflect a fluid stream from the inlet toward the outlet;
- providing one or more separation baffles extending from a bottom surface of the vessel, the baffle oriented substantially perpendicular to the elongated axis of the vessel;
- providing an outlet baffle within the vessel, the outlet baffle positioned so as to impede laminar flow of the fluid stream from the inlet to the outlet;
- discharging fluid from the outlet of the vessel;
- removing settled particulate matter from the vessel by releasing the pressure inside the vessel through the use of a pressure releasing valve;
- and
- by opening a valve proximate the inlet or by opening a valve proximate the outlet and removing said particulate matter.
