The proposed method allows, using cubic splines, the calculation of distillation trajectories and the calculation of that corresponding to the searched distillation boundaries. The algorithm is applied to 4 ternary liquid-vapour systems to test its validity. Keywords:Distillation boundary, Azeotropic distillation, Liquid-vapour equilibrium, VLE Universidade do Porto.
