Steady‐state multiplicity in an adiabatic continuous stirred tank reactor with vapor recycle

Abstract

in Wiley Online Library (wileyonlinelibrary.com).The multiplicity features of a continuous stirred tank reactor with vapor recycle have been studied for a dimerization reaction with second-order kinetics. Such reaction systems are common in the polymer industry. The aim of the analysis is to provide a simple design methodology that will ensure safe operation of the reactor. It is shown that solutions with and without vapor recycle exist. The bifurcation set for the system is calculated, and 11 different bifurcation diagrams arise. A linear relationship exists between the system parameter values, when these are normalized by their values at the ignition point. This leads to a simple method for defining a safe operating point for the system under a defined disturbance.

A New Homotopy-Based Strategy for the Robust Determination of All the Feasible Solutions for CSTR Systems

“…The field continues to receive some attention through the introduction of more complex CSTR systems (see e.g. Mjalli et al [2]; Švandová et al [3]; Kiss et al [4]; Brooks [5]; Yermakova and Anikeev [6]; Waschler et al [7]). However, the emphasis in the current studies in the literature has shifted towards the investigation of CSTR systems from the perspective of numerical solving methods [8][9][10][11][12].…”
