Synthesis of crystallization processes. Ternary systems with a single congruently soluble double salt

A method is presented for the synthesis of the process in which two solid s olutes are separated from solution by fractional crystallization. A congrue ntly soluble double salt is formed in the solid-liquid system analyzed. The method employs an exhaustive search in the space of possible process struc tures generated in a systematic way with the help of two branching operator s proposed in the paper. A computational example illustrates the applicatio n of the method.
