CHAPTER 6:The Energy Balance for Chemical Reactors

Reactor 1:The reactor volume is held constant (reactor pressure therefore changes). Reactor 2:The reactor pressure is held constant (reactor volume therefore changes). Both reactors are charged with pure A at 1.0 atm and k has the usual Arrhenius activation energy dependence on temperature, k (T ) = k 0 exp( E = T )

Completely mixed flow reactors are sometimes connected in series to create a reactor system with flow characteristics in between CMFR and PFR. CMFRs in series increase overall process efficiency because the reactants are at higher concentrations in the first reactors than they would be in a single large CMFR.
