A system and method is provided for direct condensing steam heating of oil sands process slurry streams including viscous bitumen froth and tailings products streams. Slurry viscosities greater than that of water increase cavitation and vibration issues. High solids content exacerbate component erosions. Difficult, and competing, steam and slurry interactions are managed by steam nozzle arrangements and management of steam injection at sub-sonic velocities based on a ratio of the slurry back-pressure Pb and steam supply delivery pressure Po.

The present disclosure relates to a mixer for mixing pasty components, comprising a mixing case extending along a longitudinal axis and having at least one inlet, preferably two inlets, and an outlet, and comprising at least one mixing element received in the mixing case, which defines a plurality of chambers together with the mixing case, said chambers being arranged successively and/or adjacently along a flow path from the inlets to the outlet. The chambers are defined by transverse walls, each extending perpendicularly to the longitudinal axis, and four side walls that each extend parallel to the longitudinal axis, and adjacent chambers are interconnected by a flow by means of through-openings provided in the side walls, the mixing element comprising two strips forming side walls, which are connected by a web that forms other side walls and is perpendicularly arranged in relation to the strips, a first group of chambers having first through-openings arranged in the web, which extend up to a strip, and a second group of chambers comprising second through-openings positioned at a distance to at least one strip in the web.

Methods, systems, and devices, are developed for in-situ placement of a concrete mix that can have the thixotropy to hold vertical dimension without containment, while maintaining pliability to be pumped into place and manipulated to a desired shape, and can be combined with concrete set accelerators, allowing subsequent layers of this concrete mix to be continuously stacked in place to build tall walls and such without the use of forms. Concrete without these special properties is pumped toward the point of placement where it is modified by injecting and mixing, into that line of pumped concrete, an admixture containing thixotropes, thickeners and/or set accelerators or other modifiers to provide these properties and other improvements. This method allows conventional plant batching with commonly available constituent materials for batching an economical concrete that is delivered to a jobsite and then is pumped most of the way to a point of placement.

An inclined belt conveyor capable of mixing particulate material, such as agricultural seed or fertilizer. Inserting a plurality of mixing baffles into the stream of the particulate material induces a backflow of the particulate material. In the case of wet, freshly treated plant seed, this backflow causes a mixing, polishing, and drying of the plant seed. The mixing distributes the seed treatment into an even coat by rubbing the individual seeds of the seed flow stream together. The inclined belt conveyor may also be used to blend multiple varieties or types of particulate material. The mixing baffles are oriented to induce backflow and sideways lateral movement and may incorporate a passage to allow increase particulate material flow rate. The mixing baffles can selectively deploy between an angle of 20 degrees to 70 degrees to enable the mixing inclined belt conveyor to have a transfer-speed-maximizing mode and a mixing mode.

A process for hot application of an adhesive composition (80) on a support (96), by means of a nozzle (50) applying the adhesive composition (80), a line (88) supplying the nozzle (50) with the adhesive composition (80) to be applied in fluid form, a mixer (30) positioned in the line (88) for the homogeneous mixture of the main components of the adhesive composition before its application; the applied adhesive composition (80) including a silylated prepolymer, a compatible tackifying resin; the adhesive composition having a cross-linking catalyst; the process involving: supplying the line (88) with the silylated prepolymer separated from the cross-linking catalyst, the mixing of the cross-linking catalyst with the main components by the mixer (30), the hot application of the mixed adhesive composition (80) onto a support (96).

A method for transporting a viscous fluid through a heat exchanger line that includes transporting a viscous fluid through a connecting piece with an excess pressure release component, where the excess pressure relief component separates an interior of the connecting piece from a discharge line in the connecting piece, and is fixed to an edge of the discharge line, mixing a fluid flow in a region of the excess pressure relief component using a mixing element disposed in the interior of the connecting piece and causing the excess pressure release component to release at least a portion of the fluid through the discharge line when the pressure of the fluid is equal to or greater than a preset excess pressure.

A mixer duct for mixing of a turbulent flow includes an inlet, an outlet in fluid communication with the inlet, and at least one static mixer element located between the inlet and the outlet. The at least one static mixer element includes at least two at least substantially coplanar plate-like segments spaced apart by a substantially longitudinal gap. Each segment is attached to a duct wall and comprises at least two free edges, with one free edge being a leading edge and the other free edge adjacent to the longitudinal gap. The at least two segments are inclined relative to a duct axis so that their leading edge is oriented up-stream in the mixer duct and substantially perpendicular to a direction of a main fluid flow.

A device to be installed in a pipeline, characterized by at least one static mixer and at least one pre-mixer arranged in a sleeve, wherein said at least one static mixer is characterized by: a body having a plurality of slots through the body, said slots having one or more sides that are angled with respect to an axis passing through a center of the body; a plurality of arms extending from an outer edge of the body towards a center of the body, wherein the plurality of slots comprising at least one concentric ring of slots.

A valve including a feed mechanism, a mixing element operably connected to the feed mechanism, wherein the feed mechanism delivers at least two fluids to the mixing element, the at least two fluids being mixed in the mixing element, and an air cap disposed proximate an outlet of the mixing element to atomize the mixed fluids exiting the outlet of the mixing element, is provided. Furthermore, an associated method is also provided.

A stream of seed may be maintained at a metered flow rate through multiple stages of a treatment process. These multiple stages include dispensing, first application of fluid, second application of fluid, and seed transport. Seed transport may be accomplished through a conveyor configured to maintain the metered flow rate while providing static mixing, drying, and conditioning of the treated seed. The metered stream of seed may be treated within a first treatment applicator where a first wet treatment is applied, transferred through the incline conveyor, and treated again within a second treatment applicator where a second wet treatment is applied. Overtreating in multiple stages may layer consecutive seed treatments around the treated seed. A predetermined amount of seed treatment may be applied to the coated seed based on the metered flow rate established. Maintaining the metered flow rate through multiple stages eliminates the need for multiple metering steps.
