Abstract
In this paper an estimation procedure for the heat released by chemical reactions in batch reactors is described. The estimation of the heat reaction rate is based on an energy balance on the reaction mixture and the reactor jacket. In order to use this estimation for control of the batcfrh reactor, a model of the heat of reaction as a function of measurable variables is established. Different models were considered. Identification of the respective model parameters is based on a moving horizon of past estimated values of the heat reaction rate. The resulting optimisation problem is solved using a Gauss-Newton type method. This approach has been validated by simulating the thermal control (NLMPC) of a 16 litres batch reactor equipped with a multi-fluid heating/cooling system. The simulations give some promising results.
