Continuous stirred-tank reactors (CSTRs) are frequently used plants in the chemical and food industries. Control of CSTRs is a challenging problem due to the non-linear behaviour, multiple steady-states, heat effect of the chemical reactions, time delay, and effect of various time-varying uncertainties, see ( Luyben, 2007, chap. 1 ).

Overview. There are two main basic vessel types: a tank a pipe Both types can be used as continuous reactors or batch reactors. Most commonly, reactors are run at steady-state, but can also be operated in a transient state.When a reactor is first brought back into operation (after maintenance or inoperation) it would be considered to be in a transient state, where key process variables change .

The exothermic reaction takes place at steady state in a continuous stirred-tank reactor (CSTR) with a cooling jacket. The initial volumetric flow rate is 2 when the cooling fails at 6 minutes. Once cooling is lost, the reactor temperature starts to increase. Use a slider to vary the volumetric flow rate to try to prevent thermal runaway.

Continuous stirred-tank reactors (CSTRs) are open systems, where material is free to enter or exit the system, that operate on a steady-state basis, where the conditions in the reactor don't change with time. Reactants are continuously introduced into the reactor, while products are continuously removed.
