Carbon dioxide removal is crucial step during natural gas processing, as CO₂ is highly corrosive in presence of water. There are natural gas sources around the world with very high carbon dioxide content that cannot be developed. In order to design the effective CO₂ removal process, properties of methane-carbon dioxide mixtures has to be determined. Authors have investigated thermodynamic properties of CH₄-CO₂ mixtures. Extended Peng-Robinson equations were used to determine the phase equilibrium of CH₄-CO₂ systems of different compositions.
