Read MorePredicting the Liquid Density of Gas Condensates and LNG Mixtures from Equations of State
Volume 42, Issue 2 , May 2008, , Pages 257-268
Abstract
In this contribution, two approaches are followed to predict the saturated liquid density of liquefied natural gas (LNG) mixtures. In one approach, 12 cubic equations of state (EoSs), comprising the popular Peng-Robinson (PR) and Redlich-Kwong-Soave (RKS), are employed to predict the saturated liquid ...
