Production of Oxymethylene Dimethyl Ethers from Hydrogen and Carbon Dioxide—Part I: Modeling and Analysis for OME1

“…Note that for interpreting compositions it is often convenient to consider overall mole fractions of H 2 O, MeOH, and FA (i.e., those in a fictitious mixture in which all MG n and HF n have been decomposed to H 2 O, MeOH, and FA) rather than true mole fractions including the unstable MG n and HF n . The experiments simulated for validation include (i) vapor liquid equilibria of mixtures of FA, H 2 O, and MeOH (compared quantities are vapor pressure, saturation temperature, overall gas and liquid phase composition, − true liquid phase composition, and enthalpy of vaporization), (ii) liquid density of mixtures of FA, H 2 O, and MeOH, , (iii) kinetics of OME 1 formation from MeOH and FA, and (iv) distillative separation of H 2 O, MeOH, FA, and OME 1 . Similar to the original model, the predictions agree well with the experimental data, with the restriction regarding temperature-dependence of binary interaction parameters discussed above.…”
