Abstract: | A comparison between different modern populations based optimization methods applied to the gas-solid phase calculations is
presented. Simulations are carried out in twelve binary mixtures containing supercritical carbon dioxide. Particle swarm optimization
(PSO) and genetic algorithm (GA) are used to calculate interaction parameters, solubility, and sublimation pressure on these
mixtures using the Peng-Robinson equation of state with the Wong-Sandler mixing rules. Comparing PSO with GA shows that the
performance of PSO is better than that of GA and that it is a preferable method to optimize parameters of the gas-solid equilibrium. |
