Abstract

A steady-state model is developed for a nonadiabatic bubble column with fast pseudo-nth-order reactions. A priori bounds are obtained for steady-state temperature and conversion, and analytic necessary and sufficient criteria are derived for the prediction of uniqueness and multiplicity of the steady states as a function of system physico-chemical parameters. For the special case of pseudo-first-order reactions, the occurrence of multiple steady states is shown to be more possible in a bubble column than in a gas-liquid CSTR for equivalent system parameters.
