ON THE USE OF APPROXIMATE VELOCITY PROFILES FOR MODELING MULTIPHASE REACTORS Academic Article

abstract

• The use of an approximate axial gas velocity profile in a twophase reactor model has been studied. The approximate velocity was assumed to vary linearly with conversion, which reduces the number of differential equations to be solved. The approximate model was studied in systems with one or two reactions. In most cases, the approximate and rigorous solutions were in good agreement. However, when mass transfer strongly influenced the velocity profile, errors in conversion became significant ( 15%). Reactions with no change in the number of moles are also subject to errors if the rigorous velocity profile is not accounted for. Copyright 1991 Canadian Society for Chemical Engineering
