Sulzer Mixer Reactor

Limiting ourselves to Sulzer technology, two interesting mixer types emerge. The Sulzer Mixer Reactor (SMR) is ideal for exothermal reactions, but is, however, only applicable for viscous fluids, e.g. polymers. The Sulzer SMV mixer on the other hand can be applied for mixtures in which gas is the continuous phase. For this reason jacketed cooling is of no use because the heat transfer coefficient for a gas is rather limited. An important remark must be made on this point only gas-liquid mixtures with a G/L ratio up to 10 can be handled with the SMV mixer.14 Therefore, when dealing with the model system, solutions must be found to decrease this ratio within the reaction system.

A mixing reactor was developed by Hoechst AG at the end of the 1970 s, whose square cross-section was filled with meander-shaped heat exchange tubes [382, 385], see Fig. 8.8. The individual coils of piping are inclined in an opposing sense to the neighboring position, whereby a network results, which is similar to that of the Sulzer SMX mixer. This device has been commercialized by Sulzer AG as the SMR mixer. 

Hirech et al. have described preparation of polyurea microcapsules containing hquid pesticide (e.g., diazinon) suspended in concentrated disinfectant solution, by use of a two-step microencapsulation process [28], The first step is the hquid-hquid dispersion in a Sulzer static mixer (SMX) the second step is microencapsulation by inter-fadal polymerization in a stirred-tank reactor (Fig. 5.4). It has been shown that the...
