Micromixers triangular micromixer

Figure 5.12. The chemical source term for Y2x, will be non-zero in the triangular region bordered by the line Y2co = 0 and the two lines found from setting h = 0 and h2 = 0. The mixing line corresponds to the upper limit for y2co in the range 0 < < and results from micromixing between fluid elements at (0, 0) and ( max> Y2lmK).

The triangular region in Fig. 5.12 can also be used to analyze the effect of micromixing in semi-batch reactors wherein the stream containing B is slowly added to a reactor initially containing only A. In this reactor, the mean mixture fraction is an increasing function of time ...

Micromixer-tube reactor plants have been employed both at laboratory and pilot-scale [30]. For initial process development, a triangular ( focusing ) interdigital micromixer was used (Fig. 6.18), while for the pilot scale-out a caterpillar mixer was connected to four tubes of different hydraulic diameter by a five-port valve. 

A triangular interdigital or a caterpillar micromixer followed by a tube were used (Fig. 6.30) [45]. The micromixer-tube reactor was submersed into a thermostat bath for temperature setting. The temperature was set to -10 °C to room temperature. Piston and HPLC pumps fed the bromine and aromatic flows, respectively. The use of bromine demands special materials that are stable under such harsh conditions. Fluorinated reactor materials like PVDF or glass turned out to be suitable.
