Azeotrope

Uses Simulink to compute Vapor-Liquid Equilibrium diagrams for ethanol-water binary mixture. To compute activity coefficients, program uses Van-Laar Model. This mixture presents a positive azeotrope.

Two quaternary systems are studied: (1) Acetic Acid - Ethanol - Water- Ethyl Acetate and (2) Acetic Acid - Butanol - Water- Butyl Acetate. In these two systems, liquid phase esterification occurs. The residue curve map is computed using the UNIQUAC model and gas phase acetic acid dimerization....

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...

The batch rectification unit consists of seven theoretical plates, a reboiler and a reflux drum. We fill the reboiler with a 2500 kmol of a mixture of acetone-methanol. Initially, the mixture contains a liquid mole fraction of acetone equal to 40 % mole. The vapor flow rate is set equal to 10...

The two programs computes residue curve maps for the methyl acetate and isopropyl acetate chemistries at atmospheric pressure. These calculations involve solving a complex system of differential algebraic equations (DAEs). This can be readily achieved using the built-in function of MatLab,...
