An exhaust gas treatment device (1), for an exhaust system (1) of an internal combustion engine, includes a housing (2), providing an exhaust path (3), an injector (4) arranged on the housing (2) for introducing a reduction agent into an exhaust gas flow following the exhaust gas path (3), and a mixer (7) arranged in the housing (2). The mixer (7) includes a shell (8), which encloses a mixer cross section (10) through which the exhaust gas flow can flow. The mixer (7) includes multiple guide blades (11), which on a shell inside project from the shell (8) and project into the mixer cross section (10). A simplified producibility is obtained with the mixer (7) including multiple straps (13), on a shell outside (14), which project from the shell (8) and project into a strap opening (16) formed on the housing (2) and penetrate a housing wall (15).

Methods related generally to the removal of atmospheric pollutants from the gas phase, are provided. The methods involve contacting a first stream comprising NO and/or NO.sub.2 with a second stream comprising (ClO.sub.2).sup.0 to provide a third stream comprising NO and NO.sub.2 at a molar ratio of about 1:1; and contacting the third stream with a fourth stream comprising an aqueous metal hydroxide (MOH) solution to convert NO and NO.sub.2 to MNO.sub.2.

A mixer for a vehicle exhaust system, according to an exemplary aspect of the present disclosure includes, among other things, a mixer outer shell defining an internal cavity configured to receive engine exhaust gases, the mixer outer shell having a first end and a second end opposite the first end. A baffle is associated with one of the first and second ends. The baffle comprises a body that includes at least one sensor area formed within the body.

A conveyor having a conveyance structure, mixing components, belt, and gas manifold. The gas manifold disposed within or on an exterior portion of the structure. The gas manifold having one or more manifold outlet ports to dry, condition, or treat a metered stream of seed within the conveyor. The manifold may be operably connected to a recirculating air system providing the vacuum source and pressurized air source of atmospheric or conditioned air. A filter and vacuum port may extract debris or humidity from the metered stream of seed within the conveyor. A plurality of mixing baffles may be longitudinally spaced apart through the conveyor in a laterally alternating manner to mix the metered stream of seed. The conveyor may be used to transfer, mix, dry, condition and treat the metered stream of seed between multiple stages of treatment.

An exhaust gas diffusing device includes an outside air mixing cylinder with an inner diameter larger than an outer diameter of a discharge-side end portion of an exhaust pipe to send out exhaust gas of an engine of a vehicle, the outside air mixing cylinder positioned to receive the exhaust gas from the exhaust pipe and to receive outside air to be mixed with the exhaust gas, and at least one air director at a position on the outside air mixing cylinder upstream in a direction in which the exhaust gas flows or in the exhaust pipe to promote the mixing.

Systems, apparatuses, assemblies, and methods for diesel exhaust fluid (DEF) dosing can include a body defining an injector adaptor inlet and an injector adaptor outlet; and an injector mount or interface extending from the body. The injector mount can be between the first and second ends of the injector adaptor. The injector adaptor outlet can define an area greater than an area of the injector adaptor inlet. In a side view of the injector adaptor, at a bottom side of the body, a first straight line can extend along the body from the injector adaptor inlet to the injector adaptor outlet, and at a top side of the body opposite the bottom side, a second straight line can extend along the body from the injector adaptor inlet to the injector adaptor outlet. The second straight line can be at an acute angle relative to the first straight line.

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.

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.
