Phase Equilibria Calculations of Polyethylene Solutions from SAFT-Type Equations of State

We present here phase equilibria calculations of polyethylene solutions in different solvents as obtained with two versions of the SAFT equation of state, soft-SAFT and PC-SAFT. The objective of this work is twofold: to check the accuracy of the soft-SAFT equation in providing reliable polymer solutions behavior and to propose a methodology from which systematic studies on polymer solutions can...

COMPARISON OF THE EQUATIONS OF STATE FROM JOULE-THOMSON COEFFICIENT

In the present work, we have examined the ability of some different equations of state in predicting the Joule-Thomson coefficient, ?J-T, of different fluids. For dense fluids, for which density is greater than the Boyle density, ?B, two appropriate equations of state, namely the linear isotherm regularity, LIR, and the dense system equation of state, DSEOS, have been examined. The results show...

Reliable Computation of Phase Stability and Equilibrium from the SAFT Equation of State

In recent years, molecularly-based equations of state, as typified by the SAFT (statistical associating fluid theory) approach, have become increasingly popular tools for the modeling of phase behavior. However, whether using this, or even much simpler models, the reliable calculation of phase behavior from a given model can be a very challenging computational problem. A new methodology is desc...
