Averting extinction in autothermal catalytic reactor operations

Abstract: A multiloop control system and an on-line reactor operability analysis were developed for the purpose of detecting and averting extinction of the autothermal state of a laboratory catalytic reactor. The reactor system consisted of a feed-effluent heat exchanger and two packed beds in which the exothermic reaction between hydrogen and oxygen occurred.The strategy of control was based on the preservation of the relative stability of the autothermal steady state when the reactor experienced large changes in feed … Show more

“…Several workers have developed means of regulating process outputs for relatively small disturbances. Bonvin et al (1983), Wong et al (1983), and McDermott and Mellichamp (1983) Correspondence concerning this paper should be addressed to A. S. Foss This work departs from those approaches and extends earlier work by Metchis and Foss (1987) that was directed toward averting extinction of the autothermal condition. This work reports a more general approach than that of Metchis in assessing the stability of an operating reactor.…”

“…The derivation of a model of this form from the original mass and energy balances has been fully described in the literature (e.g., Michelsen et al, 1973;Silva et al, 1979;Metchis and Foss, 1987). Central to the development is the use of the orthogonal collocation approximation of the spatial variations of temperatures and concentrations throughout the reactor.…”
