The analysis of residue curve maps is essential to know the VLE behavior of a ternary mixture, the possible existence of distillation boundaries and therefore different distillation regions in the ternary composition diagram, and the corresponding areas where the different distillation products are located. All this knowledge is necessary for the correct design of distillation column sequences especially when azeotropic distillation columns are included.<\/p>\n

As a first step, it is possible to represent qualitative residue curve maps just by knowing the equilibrium temperature of all the characteristic points (nodes) of the ternary system, i.e. pure components, and binary and ternary azeotropes (if they exist).
