Global Gibbs Free Energy Minimization In Reactive Systems Via Harmony Search, Adrian Bonilla-Petriciolet, Ma. Del Rosario Moreno-Virgen, Juan Jose Soto-Bernal
Adrian Bonilla-Petriciolet
Phase equilibrium calculations in systems subject to chemical reactions play a major role in the design of reactive separation schemes including chemical reaction engineering. Basically, these calculations involve the global minimization of Gibbs free energy constrained by the material balances and chemical equilibrium restrictions. However, Gibbs free energy function is non-convex, highly non-linear with many decision variables, and may have several local minimums including trivial and nonphysical solutions. In these conditions, conventional numerical methods are not suitable for solving reactive phase equilibrium problems. Recently, there has been a significant and increasing interest in the development of global strategies for reliably …
