Abstract:Cubic and association equations of state are two of the most widely used types of thermodynamics models. In this work, we focused on comparing the predictive capabilities of three equations of state, namely, the original Peng−Robinson, the perturbed-chain SAFT, and SAFT-VR Mie, for modeling phase equilibria of diverse types of systems. Vapor−liquid equilibria predictions from these three equations of state were evaluated using a recently published benchmark database of 200 binary systems. In addition, we compa… Show more
