For continuous polymerization reactors, the total sum of reactant (feed) flow rates (equivalent to the ratio of the reactor volume to the reactor mean residence time), has a profound effect on the .

Prediction interval-based controller for Chemical Reactor .

Abstract: Chemical Reactors, such as continuous stir tank reactor (CSTR) and polymerization reactors (PR) are nonlinear dynamics in nature. Moreover, in practice, uncertainties and disturbances always exist in operation of such kind of reactors. Therefore, the smooth tracking of these reactors is still a challenging task for the researchers.

Optimization and control of a continuous polymerization .

The polymerization reactor is usually the heart of the polymer production process and its operation may be difficult as it involves exothermic reactions, unknown reaction kinetics and high viscosity. Most styrene polymers are produced through batch or continuous polymerization processes.
