ABSTRACT:

While the first step of chemical investigations is often the synthesis of a
new product, a careful analysis quickly forces us to deal with issues
concerning the purity of the product, the amount of product, or, especially
in chemical engineering contexts, the cost of the product obtained.
Addressing these issues, directly leads us to the formulation of one or
more objective functions that need to be optimized during the synthesis
process. A common approach to solve such problems consists in performing
many experiments with carefully chosen sets of synthesis parameters and
then using statistical analyses to find optimal sets of these parameters.
However, in many cases, it is possible to write down (phenomenological)
rate equations that describe the processes involved in the development of
the chemical system. This allows us to formulate analytical objective
functions as function of state and control variables, casting the
optimization of the chemical synthesis into the language of optimal
control.[1-4]



In this talk, I am going to present a number of examples of the application
of optimal control methods to the optimization of chemical processes, such
as the optimization of a liquid-gas phase transition,[3] the optimal
control of homogeneous nucleation and growth of crystals,[4] and the
optimal control of the transfer of a chemical system between different
crystalline modifications.[5]
