2.1 Condensation of a binary mixture

One of the characteristics of condensation is that it does not take place isothermally. As an example, we will present the evolution of condensation of a mixture of water vapor and ethylene glycol at atmospheric pressure. To do this, consider the equilibrium diagram for this mixture, consisting of two curves marked K _G and $K_{\mathcal{l}}$ , and drawn at atmospheric pressure (figure 2 ). If we cool the gas mixture of molar concentration
