This paper reports the application and evaluation of a Simulated Annealing – type stochastic optimization method in several thermodynamic calculations for Chemical Engineering. This method is a modified version of the Direct Search Simulated Annealing proposed by Ali et al. [12] which is a memory-based algorithm that associates a set of points with a Markov chain and uses a probabilistic point generation mechanism. It uses a modified Metropolis criterion and an adaptive cooling schedule. Until now, it has been successfully applied in phase stability analysis of non-reacting and reacting mixtures. Considering these results, we have decided to extend the application …

In this paper, a memory-based Simulated Annealing is proposed to solve several thermodynamic calculations that are related to the modeling of phase equilibrium and thermodynamic properties. Specifically, we have tested the numerical performance of this optimization method in Gibbs energy minimization for flash calculations, calculation of homogeneous azeotropes and data fitting in thermodynamic models. Our results indicate that, in general, proposed method is reliable to solve these problems and shows a reasonable computational effort.
