Mathematical modeling and optimal control strategy development for batch crystallization process

One of the most important problems that can arise in the development of a crystallization process is the control of polymorphism, in which there exist different crystal forms for the same chemical compound. Different polymorphs can have very different properties, which motivates the design of controlled processes to ensure consistent production of the desired polymorph. Thus the optimal operation schedule is difficult to be realized by the crystallization process of heat transfer control for industrial production. In this paper the heat balance equation of state is obtained by the weight of the macro crystal, and the optimal operation rules are obtained by using the maximum principle. The practical use of the industrial practices is used to verify its practicability. The simulation and optimization of the structure of the material in the simple structure of the crystal is realized.
