Process Modeling and Simulation: CH4023 Mahinsasa Narayana Tutorial 3: CSTR case study The inlet concentration of the reactant and product are C A(in) and C B(in) (mole/l) respectively while the outlet concentration is C A and C B (mole/l). The reaction is reversible with the forward and reverse reaction being first order where the reaction rates k 1 (s -1 ) and k 2 (s -1 ) depend on the reactor temperature via the Arrhenius relationship, For this system there is no cooling coil or jacket. The manipulated variable is the inlet Temperature (T (in) ) which may be used to control either temperature (T) or product composition, C B . 1) Verify that the following mechanistic model description is valid and then simulate the system. , is specified as the time constant of the vessel and the model parameters are given by (note that some of the units per litre , l): Parameter values for CSTR simulation 2) Determine the stability characteristic of the process around the normal operating point.
