In this paper, optimization and control of a tubular reactor for thermal bulk post-polymerization of styrene have been investigated. By using the reactor mathematical model, static and dynamic simulations are carried out. Based on an objective function including polymer conversion and polydispersity, reactor optimal temperature profile has been obtained. In the absence of model mismatch, de...

Optimization of the continuous synthesis UiO-66 and derivatives with extremely high space time yield using a tubular reactor.

The multiplicity of the equilibrium profiles is analyzed for axial dispersion nonisothermal tubular reactors described by Arrhenius type nonlinear models. It is reported that there is at least one steady state among the physically feasible states for such models. Moreover physically meaninful conditions which ensure the multiplicity of equilibrium profiles are given.

This paper considers the modeling and control of a tubular fixed bed reactor with recycle stream for dimethyl ether (DME) production. For simulation purposes, a pseudo homogeneous model has been developed. By reactor simulation under steady state condition, effects of parameters such as feed rate, pressure and shell temperature are investigated. Using the steady state model, an optimizer that m...

A vast majority of material processing in industry involves homogeneous phase reactions. These reactions are carried out in batch mode as well as continuous mode. The empty tubular reactors are widely used reactor systems for continuous processing in chemical and allied industry. The heat effects due to these reactions necessitate the use of some heat removal/addition system with these reactors...
