Notes:
An application-oriented design procedure is presented for unique and point-stable operations of first-order reaction systems in a continuous stirred-tank reactor (CSTR). For a given set of values of kinetic constants, reaction enthalpy, feed conditions, residence time, and relevant physical properties, two boundary values of the heat-transfer capacity (St1, St3) and two of the modified coolant temperature (θmc, 2, θmc, 3) are analytically derived after a linearization of the unsteady mass and energy balances. With these boundary values, two separate design conditions are formulated; one for the heat-transfer capacity (HTC, characterized by St) and one for the modified coolant temperature (MCT, characterized by θmc). Each of these conditions is sufficient to guarantee unique and point-stable steady-state operations for a range of St or θmc values. Predicted behaviors of reacting systems are compared with experimental results obtained from five different systems reacting in four bench-scale and two commercial reactors.
