The present disclosure provides a quantitative tank bottom sludge valve. The extension and retraction of a cylinder drives a lower valve body, a valve rod, an upper valve body and respective accessories to move up and down, and sludge at the bottom of a water tank that is deposited to the upper part of an upper valve plate and the lower part of an upper valve body gasket is discharged quantitatively, thereby saving water and avoiding blockage; moreover, the quantitative tank bottom sludge valve has simple components in structure, and it is low in processing and assembly precision requirements, low cost, convenient to install and maintain, and suitable for mass production and use.

Removable trap stations for hydrocarbon flowlines can be implemented as an apparatus. The apparatus includes a multi-phase fluid receiver body and a tank defining an interior volume. The fluid receiver body is configured to couple to a flowline carrying a multi-phase fluid including solids and liquids. The fluid receiver body includes an inlet portion configured to receive a portion of the multi-phase fluid including a portion of the solids flowing through the flowline into the receiver body. The fluid receiver body includes an outlet portion fluidically coupled to the inlet portion. The portion of the multi-phase fluid is configured to flow from the inlet portion to the outlet portion. The tank is fluidically and detachably coupled to the outlet and is configured to receive and retain the portion of the multi-phase fluid received through the inlet portion.

A sand separation system and method for operating a sand separation system, in which the method includes separating sand from a fluid using a separator. The method includes, signaling for a blowdown unit to blowdown the separator, opening one or more blowdown valves of the blowdown unit coupled to the separator in response to the signaling, so as to blowdown the separator, and receiving the sand from the separator into a sand disposal unit. The sand passes through the one or more blowdown valves that are opened. The method includes measuring a weight of at least some of the sand that was separated in the separator using a load cell of the separator, a load cell of the sand disposal unit, or both, and determining a blowdown interval for subsequent blowdown operations of the separator based in part on the weight of the sand.

An apparatus for, and a method of, separating oil, water, gas and solid particles (usually sand) from a hydrocarbon-containing fluid produced from an oil and/or gas production facility. In particular, this invention relates to an apparatus and method for the separation of oil, water, gas and solid particles from a well or group of wells using an integrated apparatus which significantly reduces the space required on the production platform or rig and recycles produced gas to improve process efficiency while reducing cost.

A sand trap for use in oil and gas extraction operations includes a cylindrical vessel for receiving a high-pressure fluid stream with particulates. The vessel has a vertical longitudinal axis and a hollow cylindrical wall having upper and lower ends and an inlet opening generally perpendicular to but askew to the vessel longitudinal axis. Upper and lower caps extend from the upper and lower ends and have openings along the vessel longitudinal axis. An annular diverter has top and bottom ends and a longitudinal axis coaxial with the vessel longitudinal axis. A diverter outer wall permanently extends from an inner face of the cylindrical wall, and a diverter inner wall has an upper portion narrowing to a choke area and a lower portion flaring out from the choke area. A vent pipe extends from the upper cap opening to a location between the upper cap and the diverter top end.

A system for separating solids from a fluid includes a containment vessel having a V-shaped tank in fluid communication with an agitated overflow tank. Baffles within the V-shaped tank provide a series of zones where the fluid is deposited for processing. A shaftless auger at the bottom of the V-shaped tank transfers solids to an area where they are pumped to a first hydrocyclone assembly associated with a first shaker. Overflow from the hydrocyclone assembly and underflow from the first shaker is further processed by a second hydrocyclone assembly associated with a second shaker. Overflow from the second hydrocyclone assembly and underflow from the second shaker are deposited into overflow tank which contains the cleaned fluid.

Disclosed is a bioprocessing system comprising apparatus (200) including a centrifugal separation housing (210) having a temperature controllable compartment (215) for removably accepting a separation chamber (50), the apparatus further comprising at least one mixing station (250) for supporting one or more fluid storage vessels (10, 20, 30, 40), the station including a temperature controllable area (252) for increasing or decreasing the temperature of the contents of the or each supported vessel. The system further includes a disposable fluidic arrangement (100) including a centrifugal separation chamber (50) removably mountable within the compartment (215) and having one or more ports (52) allowing fluid ingress into, or egress out of the chamber, via the one or more ports in use, said ports being in fluid communication with one or more of said fluid storage vessels via fluid conduits (12, 22, 32, 42) and via one or more valve arrangements

The invention relates to an apparatus for static sedimentation tests comprising a plurality of sedimentation cylinders, which are subject to the same mixing conditions, said apparatus comprises: a. A variable number of transparent sedimentation cylinders, the most common being 12; b. Each sedimentation cylinder is located inside a non-intrusive emitter and receiving sensor housing where each housing has an electronic ID card, electronic circuit boards and connection to a control system; c. A support structure containing the sedimentation cylinders and sensor housings which rotates around an axis of rotation; d. Each sedimentation cylinder has a bottom stopper and top stopper; e. Where each bottom stopper of each sedimentation cylinder is mounted on a lateral bar parallel to the rotation axis, by a fixing to the supporting structure; f. Also the sedimentation cylinders are fixed in the supporting structure by a clamping system around the top stopper of each sedimentation cylinder g. The top stopper of each sedimentation cylinder has an additive injection system. In addition, its presented a method for static sedimentation tests carried out simultaneously and under the same mixing conditions in a plurality of sedimentation cylinders, the most common being 12; which rotate around an axis of rotation; where each sedimentation cylinder is located inside a sensor housing which are connected to a control system.
