Abstract
Catalytic fixed-bed tubular reactors can undergo severe temperature excursions particularly when there is a drop in feed temperature. Several control strategies have been studied which attenuate temperature peaks that would occur in an uncontrolled reactor. A practical strategy is recommended which requires feeding a fraction of the reactants at an intermediate point along the reactor bed. A control algorithm which enables the calculation of the secondary flow is proposed and its performance characteristics are evaluated through dynamic simulations. It is found that the proposed method is very effective in attenuating the temperature peaks, thus preventing catalyst deactivations and structural damage to the reactor.
