The enthalpy of aqueous solutions and especially the activity coefficients depend on the concentrations of the species. The new Aqueous Estimator module provides you with an easy way to estimate activity coefficients, enthalpies and heat capacities of dilute, moderate, and concentrated electrolyte solutions as a first guess for process design purposes. These estimated values may be utilized in process models and other HSC calculation modules. At this point, only homogeneous liquid phases can be calculated, i.e. precipitated phases are not yet included. The user has to specify the temperature, species, compositions, and temperature of the water solution and the module estimates activity coefficients, enthalpies, and heat capacities. |
