Abstract

Liquid phase volumes of several industrially important fluids have been calculated using seven generalized cubic equations of state. The Redlich-Kwong equation of state and three of its modifications and the Patel-Teja equation of stare and two of its modifications are considered in the study. The seven equations are applied to 27 fluids including alkanes, alkenes, aromatics, alcohols, ethers, esthers, organic oxides and inorganic compounds. The study analyzes the accuracy of these equations for predicting liquid phase volumes and gives some recommendations on which equation to use for a given situation.
