| Sumario: | Energy consumption is a purely thermodynamic concept very useful in several scientific fields such as desalination, oceanography, biology, geochemistry and environmental processes, as well as in industrial applications. In this investigation, based on a thermodynamic approach, the calculation of energy consumption was evaluated during the desalination of seawater simulated to the aqueous ternary system {NaCl + KCl}(aq). The mixing ionic parameters, obtained in our previous work, are used to predict the osmotic and activity coefficients in the aqueous solutions at different salinities ranging from 3.6 up to 72 g.L-1 at T = 298.15 K using the ion interaction model. The theoretical energy consumption of desalination was calculated at various salinities and recovery ratios. |
