Abstract:
Batch reactors are frequently used in chemical, petrochemical or biochemical industry, for the production of various quality products. Processes used are discontinuous and varied. Indeed, they are characterized by non stationary and non linear systems. An optimal control of the process; requires a modeling and a simulation of the thermal behaviors inside the agitated jacketed reactor in view of the improvement of a high product quality and conditions of security. In certain fields, where the cost and the difficulty of tests are limiting factors, it is advantageous to develop the numeric simulations of these chemical processes. Thus, this study concerns the modeling and simulation of the thermal transfer in an agitated jacketed batch reactor, it is based on a model developed from the global energy balance and empiric correlations which give relationships between thermal transfer coefficients and the stirrer speed. We have achieved the validation of the model by confronting model results with several sets of experiences; for two types of stirrers.
