Development of a Mathematical Model and a Simulator for the Analysis and Optimization of Batch Reactors. Experimental Model Characterization Using a Reaction Calorimeter

The mathematical modelling of a bench-scale 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 like heat taken by reactor wall, heat losses, stirring power supply, heat of dilution, vortex influence on heat transfer area; and a model of 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 characterisation test was carried out. Once the different parameters of the model were evaluated, some 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 neutralisation reaction between sodium hydroxide and hydrogen chloride.
