A Comparative Study on Predictions of Vapour Liquid Equilibrium of Ethylene Oxide & Water Using Simulator

In process simulation, reliable and accurate property estimation methods play an important role in the solution of various simulation problems where convergence is often traced to failures in the reliable predictions of physical and thermodynamic properties. Convergence and reliability of the simulation is heavily dependent on the fluid package selected. Predictions of phase equilibrium using various thermodynamic models provide an idea about which model will be able to represent the entire process in better way. Paper presents a review on various simulation studies done for Ethylene oxide and Water system to highlight the fact that thermodynamic models were used with little knowledge or by intuitions. A comparative study is presented for the proper selection of fluid packages by determining vapour liquid equilibrium data for Eo-Water systems (Ethylene oxide and Water). The comparison was done with the help of making a model of experimental VLE data simulated VLE data (by various thermodynamic models).
