The mixing quality of a single mixing unit and mixer arrays having
various designs was
characterized. A known test reaction for mixing quality had to be
optimized, since a much higher
sensitivity as for the characterization of macroscopic mixers was
needed. This adapted test
reaction allowed not only the characterization of the mixing
quality but also analysis of the
homogeneity of the flow distribution between parallely aligned
mixing units. A comparison of
the mixing quality to those of macroscopic reference systems (like
mixing in stirred and unstirred
vessels as well as to laminar and turbulent mixing-tees) is
presented. The mixing qualityvolume
flow dependence revealed a complex behavior, the hydrodynamic
origin of which has
been analyzed.

The performance of any device in which a kinetic process occurs e.g. disinfection, coagulation and chemical reactions is dependent on the mixing regime for a given set of operating conditions. Subsequently by characterising the mixing regime within a device and conducting batch reactor experiments to obtain specific kinetic process parameters it is possible to determine the system’s efficiency. 9th International Conference on Urban Drainage, Por...

1 edition - Ventus Publishing ApS, 2009. – 112 p. This introductory text covers the basic elements of chemical reactor design. Material and energy balances have been derived assuming simple flow patterns: perfect mixing and plug flow. Non-ideal flow is briefly discussed. Exothermic-reversible reactions have been discussed in the context of staged reactor systems. Heat and mass transfer to/from catalyst pellets has been introduced, emphasizing th...

12th European Conference on Mixing, Bologna, 27-30 June 2006 The production of sub-micron particles of organic actives has become of paramount importance in the pharmaceutical industry. One way to produce such particles is through solvent displacement where the organic active and a specific polymer are dissolved into a polar organic solvent and after mixing with water instantaneous co-precipitation of the active and polymer occurs. The polymer i...

Chemical Engineering Communications, (2001) The DISMT (Dual Indicator System for Mixing Time) mixing time/distance diagnostic encodes semi-quantitative visualization of liquid/liquid mixing processes in color changes. In DISMT, two liquids, one red and one blue, are mixed to produce a yellow liquid. Through appropriate choice of the acid-base indicators used, and the initial pH’s of the two solutions, the yellow liquid appears only in those regi...

Industrial and engineering chemistry, annual review Increased interest in fluid jets for mixing is accompanied by continuing prolific work on impeller-mixed systems. Probing into the fluid dynamics of a mixing vessel P continues.

Chemical Engineering Science 56 (2001) 2459-2473 Experiments on semibatch reaction crystallization of benzoic acid are reported. The conditions in an agitated tank are simulated by a loop reactor by which feed point mixing conditions can be controlled separately from the macroscale circulation rate. Hydrochloric acid is fed into a circulating solution of sodium benzoate and the influence of macromixing, mesomixing and micromixing on the product...

This paper presents details of a new test reaction system suitable for sparged aqueous systems at temperatures up to 100oC. This system, which is easy to use, provides the basis for experiments carried out in a standard semi-batch stirred tank reactor agitated with a Chemineer CD-6 hollow-blade impeller. The quantitative characterisation provided by liquid micromixing sheds light on the effect of temperature, and hence vapour pressure, in the ope...
