Resumen:
In this work, the modeling and optimization of an
industrial bulk process for the High Impact Polystyrene continuous production
is studied. The mathematical model for a generic reactor is based on the model
of Estenoz et al. [Aiche J., 44 (2), 427-441, 1998] and it is extended to
consider the complex kinetics associated to the use of initiator mixtures and
the presence of high temperature reactions. The devolatilization stage
considers the polymerization including the kinetics of oligomer formation and
crosslinking reactions together with the interfacial mass transfer phenomena.
The model allows the prediction of the molecular structure along the process
and the melt flow index and swelling index of the final product. Theoretical
predictions adequately reproduce the observed evolution of variables.
Engineering applications of the plant model includes the optimization of steady
state operation using a routine that is based on a Random Search Algorithm
(RSA). This is a robust method that provides a relatively good solution in
short simulation times.
