Abstract

In this work new equilibrium hydrate formation conditions for CARBON DIOXIDE and mixtures of CARBON DIOXIDE and METHANE in the 20 wt % aqueous METHANOL solution were measured by constant-volume method For CO2, these data are at temperature and pressure ranges of 264.7-270.7 K and 1.47-3.16 MPa, respectively. For mixtures of CARBON DIOXIDE and METHANE these data are at temperature and pressure ranges of 262.9-273.7 K and 1.37-5.1 MPa, respectively. The data obtained for CO2 in 20 wt % aqueous METHANOL solution in this work were in disagreement with published data in literature but there is a good agreement between thermodynamic models and our data. The Peng-Robinson equation of state (PR EOS) coupled with the Wong-Sandler (WS) mixing rule was used to obtain the fugacity of components in the gas and aqueous liquid phase. The PREDS was then coupled with van der Waals-Platteeuw (vdW-P) hydrate model and applied to predict the hydrate formation conditions of system containing METHANOL. The model predictions are compared with experimental data and good agreement is demonstrated
