FIG. 13-62 (Continued ) Sensitivity of composition and temperature profiles for MEK-MIPK-water system.

low-boiling component is removed, the still composition moves along a straight material-balance line through the initial feed composition and the low-boiling node away from the initial composition until it reaches the edge of the composition triangle or a separatrix. The path then follows the edge or separatrix to the high-boiling node of the region. At each turn a new cut is taken. Examples for the acetone-chloroform-methanol and MEK-water-MIPK systems are given in Fig. 13-63 [Bernot et al., Chem. Eng. Sci., 45, 1207 (1990)].
