SImultaneous determination of gas and liquid compressibility factors for gas condensates

摘要

The compressibility factors for the gas and liquid phases are not directly measurable during a PVT-experiment. Empirical corrleations of EOS given just rough estimates. This work presents a method for determining both compressibility factors from volumetric measurements by parameterizing their functional form and finding the coefficients by linear regression. As an alternative an iterative procedure is suggested.
