Maximizing Conversion to an Intermediate Product in a Chain of Three CSTRs in Series
This Demonstration examines a three-stage continuous-flow stirred tank reactor (CSTR). The concentration of an intermediate product of a series of consecutive reactions exiting the third reactor is to be maximized by varying the relative volumes of the reactors.
Consider the consecutive first-order reaction with and representing the reaction rate constants. The equations describing the steady state condition of three CSTRs in series are
where and are the reactant concentrations, is the flow rate, is the reactor volume for reactors , with initial concentrations and . Here , , and .
The concentration of reactant exiting the third reactor can be maximized by varying the reactor volumes.
