An exemplary pharmaceutical compounding system and device for mixing materials from at least two distinct material sources can include a valve including a valve housing and a valve structure located within the valve housing. The valve structure can be configured to permit fluid to flow through the valve when in an open position, and can include a gravity wall wherein, when the valve structure is in the open position, fluid moving through the valve structure moves upward against a force of gravity when travelling through the valve and traversing the gravity wall.

A metering and application system for a moisture-curing polymer material includes a reservoir for the polymer material and a first pump and a second pump, wherein the polymer material is conveyable by the first pump from the reservoir to the second pump. In addition, a gas metering device with a defined pressure ratio is provided to bring a gas to a defined pressure, wherein the gas metering device is connected to the input of the second pump on its outlet side. In addition, a mixer for mixing the polymer material and the gas and a valve arranged downstream of the mixer for metering and a nozzle for applying the polymer material/gas mixture are provided.

A exhaust gas mixing apparatus includes an outer cylinder being configured to an insulating ceramic; fins being configured to an insulating ceramic, the fins being provided on an inner side of the outer cylinder; and an electric heating portion embedded in at least a part of the outer cylinder and/or the fins.

A diesel exhaust system includes multiple injectors for providing diesel exhaust fluid to an exhaust to reduce NO.sub.x emissions. Two or more injectors provide DEF to the exhaust system of an engine. In one mode, the injectors alternately inject DEF fluid. In one embodiment, the system includes a NO.sub.x sensor or a NO.sub.x model to assist in determining an amount of DEF that must In be provided. In a high DEF output operating mode, the DEF amount for one injector is output at a higher rate than the other injector such that deposits may form. After the injector at the higher rate of injection operates for a selected fraction of time, the other injector provides DEF fluid at the higher rate. Further, the system calculates an estimated developed liquid film mass for each injector output. When the estimated developed liquid film mass is not less than a parameter limit film mass, the system performs ATS regeneration.

An injector mixer for a gasification reactor system that utilizes reactants includes an injector body that extends between a first face and a second face. The injector body includes a first passage that extends between the first face and the second face and has a first central axis. At least one second, impinging passage extends between the first face and second face and has an associated second central axis that has an angle with the first axis. The angle satisfies mixing efficiency Equation (I) disclosed herein.

A system for removing a gas from a liquid comprises an aeration tank for aerating a raw liquid containing a gas to remove the gas by causing an agitated air flow through the liquid. A plurality of aeration plates placed substantially horizontally across the horizontal cross sectional plane of the tank, the aeriation plates perforated by a plurality of openings. Aerating the liquid occurs with the liquid flowing downward into the aeration tank, and an airflow flowing upward through the liquid from a point proximate to the bottom of the aeriation tank, wherein the aeriation plates are configured to impart a crisscross movement pattern in the liquid flow down and the airflow up as each passes the other to agitate and mix the flow of liquid and air.

Provided are a method for supplying water of specified concentration, including: a step of adding at least two liquids, a conductive first liquid and a non-conductive second liquid, to ultrapure water to produce water of specified concentration containing a first liquid-component and a second liquid-component at specified concentrations, in which a mixed solution in which the first liquid and the second liquid are mixed at a specified mixing ratio in advance is prepared; and the mixed solution is added to the ultrapure water so that a conductivity or specific resistance of the ultrapure water after the addition satisfies a specified value, and an apparatus therefor.

A mixing assembly for an exhaust aftertreatment system includes a mixing body, an upstream plate, a downstream plate, and a swirl plate. The mixing body includes an upstream mixing body opening and a downstream mixing body opening. The upstream mixing body opening is configured to receive exhaust gas. The upstream plate is coupled to the mixing body. The upstream plate includes a plurality of upstream plate openings. Each of the plurality of upstream plate openings is configured to receive a flow percentage that is less than 50% of the total flow of the exhaust gas. The downstream plate is coupled to the mixing body downstream from the upstream plate in a direction of exhaust gas flow. The downstream plate includes a downstream plate opening. The swirl plate is positioned between the upstream plate and the downstream plate and defines a swirl collection region and a swirl concentration region.

Various implementations include an aeration device. The aeration device includes a venturi tube and an outlet tube. The venturi tube has an outlet port and an air intake port. The outlet tube has a first end coupled to the outlet port of the venturi tube, a second end opposite and spaced apart from the first end, and an intermediate portion disposed between the first and second ends of the outlet tube. The intermediate portion is helically shaped and extends around a helical axis of the intermediate portion. The intermediate portion extends at least one rotation about the helical axis.

A flow exchanger (FE) system comprising: a supplement pump receiving a supplement first fluid stream and outputting a pressurized supplement first fluid stream; a flow splitter comprising a flow restrictor, wherein the flow splitter receives the pressurized supplement first fluid stream and outputs a power stream and a treatment stream; a main flow manifold, wherein the treatment stream enters the main flow manifold subsequent to passing through the flow restrictor; and an FE cylinder filled downstream with a second fluid and having a fluid interface separator (FIS), wherein the power stream enters the FE cylinder upstream; wherein the power stream engages and pushes FIS downstream, thereby providing for a second fluid stream entering the main flow manifold; wherein a second fluid stream VFR=a power stream VFR; and wherein the main flow manifold provides for a manifold output fluid stream VFR=a pressurized supplement first fluid stream VFR.
