Application of uyou issue model in solid-liquid equilibrium calculation

Abstract

Introduction In chemical production, solid-liquid separation processes such as evaporation and crystallization are often encountered. For this process, the necessary solid-liquid equilibrium data are measured. There are very few studies on the correlation between solid-liquid balance estimation, which brings great difficulties to the design of some products, especially the development and design of some new products. In this case, we developed a method for deriving solubility. It is based on the principle of phase equilibrium and the method of using the UNIFAC model to calculate the activity coefficient of the solution.
