Resumen:
In this work, we report new experimental PvT data of non-reactive mixtures ofH2+CO2+CH3OH+H2O in the range of temperature and pressure of industrial interest.Mixtures have been prepared considering initial molar ratios of 1:3 CO2:H2, and different hypothetical stoichiometric conversions of CO2 (60 % to 94 %) to CH3OH:H2O (1:1). Isochoric studies of the multicomponent system between 0.13 g/cc and 0.5 g/cc show evidence of the phase transition, from heterogeneous to homogeneous phase condition at temperatures and pressures higher than 530 K and 240 bar, respectively. The phase equilibria and PvT data are modeled using RK-PR, a three-parameter equation of state. We selected the RK-PR because of its simplicity and proven accuracy to represent volumetric properties of other hydrogenation reactors.
