The practical applications are vast for they are used in the design of separation equipment, solvent selection, the design of pharmaceuticals, stripping operations, leaching operations, and the extraction of dilute materials . Previous studies have also shown that limiting activity coefficients can be used to predict the formation of an azeotrope . The equilibrium composition of a dilute mixture can also be determined, thus having industrial applications in azeotropic distillation and high-purity extraction . This can serve as a means for process intensification in the environmental sphere, since environmental engineering addresses the implications of a chemical very dilute in a phase, often requiring dilute separation processes . For example, limiting activity coefficients can be used to determine partition coefficients for a dilute species between two phases, which is critical in predicting the bio-accumulation of long-lived chemicals in the environment and food chain .
