JACOME, P. A. D.; PEIXOTO, F. C.; PLATT, G. M.  and  AHON, V. R. R.. A new approach to distillation of continuous mixtures: modelling and simulation. Lat. Am. appl. res. [online]. 2005, vol.35, n.3, pp.233-239. ISSN 0327-0793.

Continuous Mixtures are mixtures of so many components that is no longer useful to distinguish among chemical species. Instead, an index is chosen to characterize each molecule, such as carbon atoms in each substructure, chromatographic retention time or normal boiling point and the continuity of this index is admitted. The present work aims the mathematical formulation and the simulation of a distillation column in which a continuous mixture is fed. This is performed with the assumption of a mixture of linear paraffins, in which ideal mixture hypothesis in both liquid and gas phases are reasonable. A quadrature method is employed to calculate the integrals which turns the functional-algebraic problem into a numerical one.

Keywords : Continuous Mixtures; Distillation; Quadrature Method.
