Residue Curve Map for the mixture MTBE/Methanol/isobu​tene/n-butane at P=1 atm

Computation of the residue curve map for the MTBE chemistry is presented in the program. The equilibrium, taking place in the liquid phase, transforms methanol and isobutene into MTBE with n-butane being an inert component. Thermodynamic data can be found in the excellent paper by Niang and Mikitenko, Revue de l?Institut Francais du Petrole, Vol. 53, N° 4, Juillet-Aout, p. 439-462, 1998. This mixture presents a non reactive azeotrope and a pseudo-reactive azeotrope. The same problem was solved using Mathematica and is available at the Wolfram Research Information Center (http://library.wolfram.com/infocenter/search/?search_results=1;search_person_id=1536).
