Heat transfer for chemical reactions

In heat transfer processes in agitated tanks, there are two engineering objectives: (1) to have good fluid circulation in the bulk of the tank and (2) to have good fluid exchange and circulation to and from the heating and/or cooling element. Often, the elimination of local hot spots becomes a primary objective since hot spots can cause loss of product quality or induce thermal runaway reactions.

Heat transfer becomes an important objective in larger processes and may become the limiting factor on the size of the process. Some volume processes, such as exothermic reactions, release significant amounts of heat. Other volume processes require significant amount of heat. Heating and cooling jackets are not effective on volume processes.
