The invention provides a centrifugal pump, distinctive in that the pump comprises two or more stages; the last stage in the direction of flow has been adapted so that it provides a larger equilibrium droplet size than the upstream stages. Method of designing the pump and use of the pump.

Centrifugal pump with coalescing effect, design method and use thereof

A water injection flow control device includes a stack of discs or cone-like plates that form spiral-shaped flow conduits. The spiral-shaped flow conduits form at least one revolution about a central point or axis and depart or approach the central point or axis for each revolution. At least some of the spiral-shaped flow conduits have sections in series with alternating cross sectional area for flow and at least some have sections with a serpentine-type shape for flow along the spiral-shaped flow conduits. The spiral-shaped flow conduits have an inlet coupled to an inner or outer end of the spiral shaped flow conduits, an outlet coupled to the other end of the spiral-shaped conduits, and a control member.

A flow and fluid conditioning pressure reduction valve or device includes an inlet and an outlet. The valve or device includes at least one relatively long flow bore conduit shaped as a spiral or a spiral arranged on the surface of a disc or cone. Each spiral shaped conduit includes at least one rotation and each spiral shaped conduit may be closely packed. The conduit arranged between the inlet and the outlet has reduced flow cross section area, and the length, the cross section area, and the number of the spiral shaped conduits in line determine the pressure reduction of a given fluid at a given flow rate.

Flow and fluid conditioning pressure reducing valve or device

The invention provides a sample container arrangement for collecting multiphase samples of gas and liquid, particularly oil in water samples that are representative with respect to oil concentration, oil droplet size and oil droplet size distribution, the sample container arrangement comprises a sample container with an upper end, a lower end and a container volume for sample collection, such as a standing cylinder, distinctive in that the container arrangement further comprises: one inlet connected to the upper end or part of the container volume, one outlet with a valve with bleeding function, connected to the upper end or part of the container volume, and one outlet connected to the lower end of the container volume.

Multiphase sample container and method

A flow and fluid conditioning pressure reduction device includes an inlet and an outlet. The pressure reduction device is distinctive in that it comprises at least one relatively long flow bore conduit shaped as a spiral or a spiral arranged on the surface of a cone or frustum. Each spiral shaped conduit includes at least one, preferably at least three rotations and each spiral shaped conduit preferably is closely packed; the conduit has been arranged between the inlet and the outlet, has reduced flow cross section area, and the length, the cross section area and the number of the spiral shaped conduits in line determine the pressure reduction of a given fluid at a given flow rate.

An arrangement for a control valve for controlling pressure and flow rate of a fluid, the fluid flowing via an inlet into the control valve being brought to rotate about a main flow axis before the fluid, at least with reduced pressure or speed energy, flows via an outlet opening from the control valve and where at least one inlet port communicating with the inlet being provided tangentially in relation to an inlet portion of the speed reduction chamber located in the control valve, and where the speed reduction chamber, provided substantially concentric with the main flow axis, is divergent over at least the first portion of the main flow direction.

Choke valve device

The invention provides a fluid flow control valve () comprising a cylindrical inlet chamber () having a fluid inlet aperture () and a coaxial waisted cylindrical outlet chamber () having a fluid outlet aperture (), said inlet chamber containing a coaxial cylindrical cage () opening into said outlet chamber and said cage having in its cylinder wall at least one valve aperture () to allow fluid to pass from said fluid inlet aperture into said outlet chamber, said control valve further comprising a coaxial cylindrical plug () movable axially relative to said cage to close and open said valve aperture and a valve actuator () operable to move said plug or cage relative to each other whereby to close or open said valve aperture, wherein said valve aperture is arranged to provide fluid exiting said cage from said inlet chamber with a velocity component tangential to the cylindrical axis () of said cage.
