Derive the operating equations for the two middle operating sections when an intermediate reboiler is used (see Figures 4-22A and 4-22B). Show that the operating line with slope of \(\mathrm{L}^{\prime} / \mathrm{V}^{\prime}\) goes through the point \(\mathrm{y}=\mathrm{x}=\mathrm{x}_{\mathrm{B}}\).
