Comparative study of eight equations of state for predicting hydrocarbon volumetric phase behavior
The objective of this study is to present a review of eight equations of state and compare their ability to predict the volumetric and phase equilibria of gas condensate systems. Included in the study are the Peng-Robinson, the Soave-Redlich-Kwong, the Schmidt-Wenzel, the Usdin-McAuliffe, the Heyen, the Kubic, the Adachi-Lu, and the Patel-Teja equations of state. The Schmidt and Wenzel equation exhibits a superior predictive capability for volumetric properties of condensate systems. The Peng-Robinson equation is found to accurately represent the phase equilibrium behavior of condensate systems. In terms of compressibiity factors, the Schmidt-Wenzel and Patel-Teja equations give better predictions than other equations.
