Modeling and calculation of thermodynamic properties and phase equilibria of oil and gas condensate fractions based on two generalized multiparameter equations of state

摘要

Based on two generalized equations of state, previously developed by the authors, describing the properties of hydrocarbon chain and cyclic structures, a method for the predictive calculation of thermodynamic properties and phase equilibria of complex hydrocarbon mixtures (petroleum and gas condensate fractions) has been developed. The method is applicable over a temperature range from the freezing point to 700 K and at pressures up to 100 MPa, including the liquid and gas phases as well as the supercritical region.
