Modelling of falling film reactors

Abstract

An improved mathematical model for falling film reactors is presented. Effects of liquid film turbulence, gas phase heat and mass transfer resistances, gas-liquid interfacial drag, exothermic chemical reaction and heat transfer within the system, as well as volatility of liquid film are considered. The model predicts liquid phase chemical conversions and the interfacial temperatures along the reactor length. Model predictions agreed well with data from both laboratory and industrial scale reactors.
