Consider
binary and ternary mixtures of aromatic compounds composed of
benzene/toluene and benzene/toluene/p-xylene, respectively. The present
study shows how one can apply both mass and energy balance equations in
order to understand the separation of such ideal mixtures by
distillation. An adiabatic flash distillation problem is solved
graphically for a mixture composed of benzene/toluene. Rigorous resolution
of a steady-state binary distillation problem, using Mathematica® and
the same benzene/toluene mixture, shows perfect agreement with results
obtained using HYSYS. Results of a dynamic simulation involving the
solution of a relatively large system of differential algebraic
equations are presented and discussed for the benzene/toluene mixture.
SIMULINK© and Mathematica® are used to perform control of this binary
distillation column. Finally, a steady-state simulation of a simple
multicomponent mixture, composed of benzene/toluene/p-xylene, is studied
and some qualitative results are drawn from both the temperature and
composition profiles. Comput Appl Eng Educ © 2011 Wiley Periodicals,
