Sažetak

Computational analysis of salt separation from two-component electrolytic system is presented. A case study of an electrolytic system KNO₃-H₂O was used to illustrate the analysis of evaporation and crystallization. The following processes are considered: two-stage evaporation system and vacuum crystallizer with adiabatic cooling. A mathematical model of the two-stage evaporation system and vacuum crystallizer was developed. The mathematical model is comprised of algebraic equations. The proposed model was developed in Microsoft Excel with VBA (Visual Basic for Applications). The developed model enables analysis of existing or design of new evaporation and crystallization processes. The developed model can be applied for any two-component electrolyte system, but requires the input of physicochemical properties related to corresponding electrolyte system.
