A method and device for in-line injecting of flocculated agent into a fluid flow of mature fine tailings (MAT). The method includes the steps of: a) providing a fluid flow of mature fine tailings to be treated along a given channel fluidly connected to the pipeline; b) providing a source of flocculating agent; and c) introducing flocculating agent inside the fluid flow of mature fine tailings via a plurality of injection outlets for injecting the flocculating agent into the fluid flow in a dispersed manner so as to increase an exposed surface area of the injected flocculating agent and thus increase a corresponding reaction with the mature fine tailings, for an improved flocculation of said mature fine tailings, and/or other desired end results. Also disclosed is a kit with corresponding components for assembling the in-line injection device to be connected in-line with the pipeline carrying the mature fine tailings to be treated.

A process for dewatering oil sand fine tailings is provided and comprises a dispersion and floc build-up stage comprising in-line addition of a flocculent solution comprising an effective amount of flocculation reagent into a flow of the oil sand fine tailings; a gel stage wherein flocculated oil sand fine tailings is transported in-line and subjected to shear conditioning; a floc breakdown and water release stage wherein the flocculated oil sand fine tailings releases water and decreases in yield shear stress, while avoiding an oversheared zone; depositing the flocculated oil sand fine tailings onto a deposition area to form a deposit and to enable the release water to flow away from the deposit, preferably done in a pipeline reactor and managing shear according to yield stress and CST information and achieves enhanced dewatering.

A device for mixing two gas streams, the device includes: an inner pipe, wherein: the inner pipe is arranged substantially concentrically within an outer pipe and forms an annulus between an outer diameter of the inner pipe and an inner diameter of the outside pipe; the inner pipe is closed at a downstream end; and the inner pipe comprises a plurality of perforations; and the outer pipe, wherein: a downstream end of the outer pipe extends into a reactor; the outer pipe is closed at the downstream end; and the downstream end of the outer pipe comprises a plurality of perforations. The mixed gas stream can enter the reactor. The reactor can be an Oxidative Coupling of Methane (OCM) reactor.

A nozzle including a first end and a second end. The first end includes at least a first inlet and a second inlet and the second end includes a plurality of outlets. An exterior surface extends from the first end to the second end of the nozzle. A plurality of vanes are disposed on the exterior surface and extend from the first end to the second end of the nozzle. A plurality of channels form along the exterior surface of the nozzle.

A nozzle including a first channel, a second channel annularly disposed around the first channel, and a plurality of third channels fluidly connected to the second channel. The nozzle includes an interior cavity having a first inlet fluidly connected to the first channel and a plurality of second inlets. Individual second inlets of the plurality of second inlets fluidly connect to individual third channels of the plurality of third channels. The interior cavity includes an outlet and an impinging surface located opposite the first inlet.

A valve comprising a valve spindle housing located in the side of the chamber and including a first fluid inlet and a first fluid outlet, and a cylinder open along a portion of a longitudinal axis of the cylinder and rotatably mounted in the valve spindle housing. The cylinder is positioned in one position so that the cylinder completely obstructs the valve spindle housing outlet, not allowing any fluid to pass around the cylinder. The cylinder walls are solid except for having openings through a portion of the cylinder, so that when rotated to a closed position, the solid portion of the cylinder fully obstructs the valve spindle housing outlet, and when rotated to an open position, the first fluid can pass into the inside of the cylinder and then through the openings and out of the valve spindle housing.

Disclosed is a beverage dispensing machine and a gas infused beverage dispensing system which facilitates combination of gas with in a configuration which provides a smaller footprint and provides gas infusion of a beverage on demand. The system may be configured to produce only gas infused beverage or to allow the user to select gas infused beverage or chilled beverage, and, alternatively, ambient, unchilled beverage. A gas infuser of the system introduces gas to a chilled beverage stream using an injector with slots. This inline, on-demand gas infusion system provides benefits over infusion tank systems that gas infuse a relatively large volume of beverage in bulk.

A flotation separation system for partitioning a slurry comprises a flotation separation cell that comprises a sparger unit and a separation tank. The sparger unit comprises a slurry inlet for receiving a slurry and a gas inlet for introducing a gas into the slurry. The sparging mechanism disperses the gas bubbles within the slurry. A high shear element comprising a rotating shaft and a rotating high shear element mounted to it located within the sparging mechanism shears the gas into a bubble dispersion within the slurry. A slurry outlet discharges the slurry containing the bubble dispersion into the separation tank. An adjustable distributor plate at the slurry outlet restricts the flow of slurry through the slurry outlet. The distributor plate is mounted to the rotating shaft and rotates with the high shear element.
