A generalized method for the solid-liquid equilibrium stage and its application in process simulation

For the important need of simulations of the crystallization process in aqueous electrolyte solutions, a generalized method is proposed in this paper for predicting the solid-liquid equilibrium stage by identifying the number of phases and their identities automatically. The proposed method is also used to generate phase diagrams and crystallization paths and to provide. an example of the software that can be used to design, simulate, and optimize the related process. Several cases are studied to demonstrate the capability of the proposed method for systems with hydrate, multi-ion, and complex salts.
