WebTo account for heat effects in multiple reactions, we simply replace the term (-delta H RX) (-r A) in equations (12-35) PFR/PBR and (12-40) CSTR by: PFR/PBR. CSTR . These equations are coupled with the mole balances and rate law equations discussed in Chapter 6. Textbook Example (Alternative Solution) WebA batch reactor (BR) is one in which reactants are initially charged into a container, are well mixed, and are left to react for a certain period. The resultant mixture is then discharged. ... Like a CSTR, the PFR also represents an open system, and hence steady states are not states of reaction equilibrium. Owing to the ows ohioWebIt can be demonstrated that an infinite number of infinitely small CSTRs operating in series would be equivalent to a PFR. The behavior of a CSTR is often approximated or modeled by that of a Continuous Ideally Stirred-Tank Reactor (CISTR). All calculations performed with CISTRs assume perfect mixing.
