Process Intensification in a Double-Pipe Reactor with Additively Manufactured Internal Inserts

The polycondensation reaction to produce polydextrose can be intensified by using micro-process engineering. Fluid Guiding Elements are additively manufactured internal inserts that have already shown their potential intensify heat transfer in double-pipe exchangers. This study investigated the intensification of yield when these were used. Different reactor lengths and geometries, as well different operating conditions, analyzed. experiments showed reactant concentration had no effect on product yield. Furthermore, it was process could at higher temperatures, with relatively low residence times lower pressures. It confirmed good characteristics allow them continuously evaporate water during further reach required temperature, thus shifting equilibrium towards desired product. These findings special significance for optimization polydextrose.
