CHAPTER 8: Mixing in Chemical Reactors

ow reactorsare useful for modeling many complex chemical reactors. Up to this point we have neglected a careful treatment of the uid ow pattern within the reactor. In this chapter we explore some of the limits of this approach and develop methods to address and overcome some of the more obvious limitations. 1/130 Scope of problem The general topic of mixing, even in the restricted context of ...

ChE 344 - Mixing in Chemical Reactors

Mixing is an extremely important part of the chemical process industry, and is necessary in almost every chemical process. If mixing is not present among the reacting species of a process, no or little reaction will take place. Although it is not addressed in depth in most engineering curricula, the determination of the correct type, geometry, and size of mixers and/or impellers to be used for ...
