First, consider the representation of a mixer on the triangular diagram3. Figure 12.4a shows a mixer for two streams P and R producing a mixed product Q. An overall... 

A ternary mixture of mole fraction ethanol of 0.15, ethyl acetate of 0.6 and methanol 0.25 is to be separated into relatively pure products. Sketch a system of distillation columns and mixer arrangements in the triangular diagram to carry out the separation by exploiting the shift in the distillation boundary with pressure. Sketch the flowsheet corresponding with this mass balance. 

Geometric focusing via triangular-shaped focusing chambers using horizontal co-flow injection schemes has become state-of-the-art for interdigital mixers (see Figure 1.77) [20, 35, 37,124],...

Figure 1.86 Design of an optimized triangular interdigital micro mixer, termed SuperFocus, and SEM image showing detail of the corresponding feeding zone [20] (by courtesy of AlChE).

The glass version of the SuperFocus mixer is composed of three layers containing similar structures to the standard triangular mixer [M 43] (see above) [20, 37, 39, 121]. Photoetching of a specially glass is used for manufacture. 

M 43] [P 39] A regular multi-lamination pattern composed of 30 lamellae is found for a triangular interdigital mixer [20,39], Within the limits of a photographic image no notable deviations are observed. 

The second major difference of the flow patterns of the triangular to the rectangular mixers that more complex concentration profiles are found which have more peaks than the number of generated lamellae [20], This becomes evident at volume flows > 200 ml h-1. 

M 43] [M 36] [P 41] The liquid mixing time was calculated to be 59 ms for a standard triangular mixer creating lamellae about 110 pm thick (see Table 1.6) [39], For comparison, the liquid mixing time of the rectangular mixer having 100 pm thin lamellae is 2.48 s.
