Abstract

Reactors that operate in industrial plants are non-isothermal and thus, complex dynamic nature is expected. In order to design controllers with improved control performance, there is a need to study the dynamic behaviour of non-isothermal reactors. Dynamic modelling through mathematical modelling (which involves equations of physical and chemical laws) was conducted in this research. Polymerization reactors were the focus in this research which largely relied on the model and data taken from literature. Polymerization reactor is difficult to control due to its complicated reaction mechanism. To study its dynamic characteristics, the Melt Index of the produced polymer is controlled by manipulating the feed rates of hydrogen, FinyH2,in. This step has yielded the understanding that the quality of the polymer materials must be regulated to obtain the desired product. The steady state gain, K is developed from the transfer function model study. Steady state gain, K increases with the step changes in feed rates of hydrogen. The outcome of the study on K indicates the polymerization reactor has non-linear behaviour.
