✦ Synopsis

A general method for the calculation of various types of phase diagrams for aqueous electrolyte mixtures is outlined. It is shown how the thermodynamic equilibrium precipitation process can be used to satisfy the operational needs of industrial crystallizer/centrifuge units. Examples of simulation and optimization of fractional crystallization processes are shown. In one of these examples, a process with multiple steady states is analyzed. The thermodynamic model applied for describing the highly non-ideal aqueous electrolyte systems is the Extended UNIQUAC model.

Abstract. Polymer crystallization may be modelled by a stochastic birth-andgrowth process, with temperature dependent parameters. The temperature field is itself stochastic, because of the relcase of latent heat, due to the phase change. A mathematical model which couples the evolution of crystal gr
