A system for removing particulate matter from a multiphase stream comprising gas, liquid and the particulate matter. The system comprises a first vessel for receiving the multiphase stream and separating a majority of gas from the multiphase stream and collecting a slurry of liquid and particulate matter; a second vessel for receiving the slurry and causing separation of the particulate matter from the liquid and for generating a pressure head of liquid against the particulate matter; a third vessel for receiving the particulate matter from the second vessel and collecting the particulate matter until a pre-determined mass or volume of particulate matter is collected; and an outlet in the third vessel for conveying the particulate matter out of the third vessel.

A system for determining the level of solids accumulated in a sand separator has a vibratory level sensor and a solid separator control system. The vibratory level sensor includes a vibratory rod and an exciter connected to the vibratory rod. In some embodiments, a vibration sensor is connected to the vibratory rod to monitor changes in the vibration of the rod. In other embodiments, changes in vibration are measured by looking at the rotational speed and power inputs at the exciter.

Fluid treatment systems and components are provided for a removal of solid matter from water or other fluids in which a chemical or chemicals may be introduced into the fluid under pressure to coagulate and/or conglomerate the solid materials and cause them to be dropped out of the treatment system and be removed. The fluid treatment system can include: an equalization chamber receiving a wastewater; a clarification chamber receiving a partially separated water from the equalization chamber; a mixing tube having an inlet end and an outlet end; and a sludge detector.

An apparatus for washing solid particles removed from a hydrocarbon-containing fluid produced from an oil and gas production facility using a company automated unit. The apparatus comprises an inlet that carries a mixture of solids particles and water flushed from a de-sander.

A fluid treatment system combines cyclonic separators and gravitational separators for use in onshore and offshore oil and gas operations and elsewhere. The characteristics of apertures that interface between a gravitational separation chamber and a cyclonic separator are configurable in accordance with operational requirements. By selecting aperture characteristics, improved control and separation efficiencies can be achieved.

A system and methods are disclosed for treating cooling fluid in a continuous metal casting process having a spray chamber. In some embodiments, the system includes a first compartment with an intermittently operable outlet (e.g., valve) with an open state and a closed state, for removing particulate matter, and a second compartment that receives particle-free fluid from the first compartment. The first compartment may be tapered, conical, funnel, pyramidal shape or otherwise narrowed shape to facilitate settling of the particles. One or more sensors measure at least one property of the particle-free fluid to determine the opened or closed state of the outlet and to adjust chemical additives for the cooling fluid. In some embodiments, the system and methods reduce corrosion in spray chambers.

A cyclonic inlet diverter for initiating the separation of a multi-phase inlet fluid flow comprises an enclosed tubular body mounted crosswise within a larger separator vessel. The inlet diverter includes a splitter plate positioned within a center portion of the tubular body and configured to split the inlet flow into a first stream and a second stream, and a swirl plate positioned on each side of the splitter plate with angled surfaces configured to increase the cyclonic motion of the first and second streams within the tubular body. The inlet diverter further includes elongate apertures formed through bottom sidewall portions of the tubular body on each side of the splitter plate, an axial aperture formed through opposing end caps of the tubular body, and at least one radial aperture formed through lateral sidewall portions of the tubular body proximate each opposing end cap.

A feedwell comprising a plurality of holes disposed in a bottom thereof, at least some of the holes having a tube disposed thereabout which extends downward or otherwise away from an interior of the feedwell. Optionally, a large center hole can be provided and it can have a tube disposed around it. By providing a plurality of holes spread across a large portion of the bottom of the feedwell, lower velocity flow rates from the feedwell to a sedimentation chamber can be provided, thus reducing induced turbulence in the fluid within the sedimentation chamber, while still providing sufficient separation of the feedwell from the sedimentation chamber so that the contents of the feedwell can be properly and adequately mixed.

Techniques and apparatus for separating a Flowback mixture received from a wellbore. Employing a vessel or system of vessels to receive the fluid mixture and configured to manage the discharge of gases, liquids, and solids to maintain a vapor barrier in the vessel(s) to prevent unwanted release of gas to the atmosphere.

A passive filter cell having a basin with a floor and two or more vertical or upright sidewalls forming chute or container having first or left sidewall, second or right sidewall, and third or back sidewall, and fourth or front downwardly curved sidewall, an inlet positioned proximate a top of the fourth or front sidewall and an outlet positioned proximate the top of the third or back sidewall, wherein the floor is configured angled from the fourth or front sidewall to the third or back sidewall, discharge pipe positioned proximate junction between the floor and the third or back sidewall, and lip configured to extend from the top of the third or back sidewall into an interior of the basin.
