Lecture 24: Continuously stirred tank reactors - Chemistry .

While such reactions are commonplace in chemistry labs, most industrial processes instead use continuously stirred tank reactors (CSTRs). In these reactors, reactants are continuously flowed into the reactor, where they undergo a chemical reaction. Simultaneously, an exit stream is extracted from the reactor at the same flow rate as the inlet .
