Mixer mixing

Micro reactors show, under certain conditions, low axial flow dispersion reactions with unstable intermediates can be carried out in a fast, stepwise manner on millisecond time-scales. Today s micro mixers mix on a millisecond scale and below [40]. Hence in micro reactors reactions can be carried out in the manner of a quench-flow analysis, used for determination of fast kinetics [93]. 

In turn, the interdigital micro mixer mixes much faster, provides more unique concentration profiles before reaction takes place and consequently changes the course of the reaction [125]. As a result, no high-molecular-weight polymer fraction is observed by GPC measurement and no fouling occurs, although the specific wall surfaces of the micro device are expected to promote deposition.

Dry products can include dusts, powders, and granules. Dusts and powders are manufactured by mixing technical grade material with the appropriate inert carrier and grinding the mixture to obtain the correct particle size. Several rotary or ribbon blender-type mixers mix the product. Figure 6 shows a typical dry formulation unit for pesticides [8].

Propane is stored underpressure to keep it liquid. Unlike LNG, propane does not need anything other than a modest pressure to keep it liquefied. The tanks that store propane are pressure vessels, but since they can be made from low-carbon steel their price is modest compared to CNG and LNG tanks. The propane is vaporized in a device called the converter that lowers the pressure of the propane to vaporize it. The converter also uses engine coolant to warm the propane to ensure that it is completely vaporized when it passes on to the mixer. As its name suggests, the mixer mixes the propane and air in the desired ratio before it enters the engine. Other controls and compensation for temperature are included in the propane fuel system. Propane fuel systems can also incorporate feedback control to work with three-way catalyst emission control systems.

For CSTRs, was assumed to be 1, while for in-line mixers mix was assumed to be between 0.5 and 0.9. A surface reaction rate of 1.5 /Js was assumed to allow for a possible change in reaction mechanism at high acid concentrations not ruled out by the experimental data. The particle size distribution was assumed to be given by Eq. (57) ...
