Aspen Process Simulation Software Does All Mass Balances Mole balances for reactions Does All Energy Balances Keeps Track of Thermo Phase Equilibrium Reaction Equilibrium

Thermo Methods

Which Thermo Package Do I use? See Property Prediction PowerPoint

Problem 1 Vapor Liquid Equilibria Ethanol – water

Problem 2 Liquid-Liquid Equilibria Polar - polar

Problem 3 Liquid-Liquid Equilibria Polar - non-polar

Lecture 1- Problem 4 Multiple component phase equilibria Methane – 0.1 mole fraction Ethane – 0.2 Propane- 0.3 Butane- 0.3 Methyl ethyl keytone -0.1 10 atm, 10°C Use Ideal and Peng Robinson Thermo Pkg. Compare results

Problem -5 Use Gibbs Minimization reactor in Aspen to determine the products of reaction at 10 atm and 200 C.
