  • Development of a mathematical model and a simulator for the analysis and optimization of batch reactors : Experimental model characterization using a reaction calorimeter

Abstract

The mathematical modelling of the bench-scale batch reactor is presented. The formulation of the mass and heat balances leads to a set of algebraic differential equations which, when solved, produce the temperature and concentrations profiles as a function of time. Emphasis has been placed on a realistic description of such a reactor by incorporating an accurate representation of heat effects such as heat taken by reactor wall, heat losses, stirring power supply, heat of dilution, vortex influence on heat transfer area; and a model for the heating/cooling circuits as well as their controllers. To obtain the data necessary to simulate the dynamic behaviour of the reactor a set of characterization tests was carried out. Once the different parameters of the model were evaluated, experiments were performed to compare with the predicted dynamic behaviour obtained with the simulator. These experiments included: heating/cooling dynamic behaviour with different fluids and a neutralization reaction between sodium hydroxide and hydrogen chloride.
