Maximum allowable temperatures in chemical reactors
TL;DR: In this article, the required cooling capacity in tank reactors to obtain a high conversion to desired product and to prevent excessive degradation of the reagent to unwanted products is discussed, and temperature limits, as normally specified in practice, are shown to depend on the residence time in the reactor.
