Dynamic behaviour of a semibatch non-isothermal gas-liquid reactor

Abstract

A dynamic model to predict transient temperature profiles of a nonisothermal semibatch gas-liquid reactor was developed. The enhancement factor for non-isothermal gas absorption was calculated by extending the model of Bhattacharya et al. (AIChE J (1987) 33 1507) to incorporate the effect of finite gas film resistance. For a particular combination of values of heat of reaction, heat transfer and activation energy parameters, transient temperature profiles of the semibatch reactor were found to be highly parameter sensitive. In the reactor model, gas phase dynamics were taken into account and heat generated in the reactor was assumed to be removed by a coolant flowing through a cooling coil.
