Gas-liquid reactor/separator: dynamics and operability characteristics

A comprehensive mathematical model is developed to simulate gas-liquid reac tor in which both, reactants as well as products enter or leave the reactor in gas phase while the reactions take place in liquid phase. A case of fir st-order reaction (isothermal) was investigated in detail using the dynamic model and numerical bifurcation tools. Strong coupling between reaction ki netics and product removal rate was found to lead to complex dynamic (inclu ding over-flow/dry-up or oscillatory) behaviour. Key parameters controlling operability and dynamic characteristics were identified. Operability maps of the reactor/separator are presented. The model and results discussed wil l be useful for design and operation of industrial reactor/separators. (C) 1999 Elsevier Science Ltd. All rights reserved.
