Study on calculation of phase equilibrium in mixed aqueous electrolyte solutions
混合电解质水溶液相平衡计算的研究

A mixed-integer non linear programming(MINLP) model is established for computing phase equilibrium in mixed aqueous electrolyte solutions and a genetic algorithm(GA) is proposed to solve the model.Firstly,based on minimization of Gibbs free energy,the model is established by using a coding method for liquid and crystal salts,and the computation of multiphase equilibrium is transformed into constrained minimization problem.Secondly,the minimization problem is solved by GA,a dynamic coding method that can lim...
