Start-up and safeguarding of an industrial adiabatic tubular reactor

Boundary control for an industrial under-actuated tubular chemical reactor

Several control strategies are presented and studied for an industrial under-actuated tubular chemical reactor. This work presents a case-study of the performance of a decentralized versus centralized control strategy. The tubular reactor under consideration is characterized by nonlinear kinetic laws, and it has some structural constraints on the location of the heat exchangers and of the senso...

Dynamic start-up optimization of a plate reactor with uncertainties

In this paper, start-up of a plate reactor with an exothermic reaction is considered. Dynamic optimization is used to obtain start-up trajectories, while a feedback control system is designed for on-line control. The problem is challenging, since the process model is highly non-linear, and subject to uncertainty. Limited bandwidth of the feedback control system requires that the optimization gi...

Steady State Operability Characteristics of an Adiabatic Fixed-Bed Reactor for Methanol Dehydration

Operability analysis as one of the most important bridges between process design and process control helps the process designer to investigate the control issues quite early in the design stage. Recently, Vinson and Georgakis suggested a steady state geometrical operability index as a quantitative measure for assessment of process operability. In...
