Continuous Stirred Tank Reactors - Chemical Engineering

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.

Chemical reactor - Wikipedia

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.
