Oxymethylene dimethyl ethers (OME_n) are potential compression ignition fuels or blend components that enable drastic reductions in pollutant formation. By combining multiple conversion steps, OME_n can be produced from carbon dioxide (CO₂) and hydrogen (H₂) and hence from renewable electricity. However, established processes for OME_n production are challenging to model and detailed analyses of OME_n production from H₂ and CO₂ are not yet available in the open literature. In the first part of our two-part article, state-of-the-art models for the formaldehyde-containing mixtures involved in OME_n production are implemented in AspenPlus and used to analyze a process chain for production of OME₁ from H₂ and CO₂ via methanol and aqueous formaldehyde solution. The exergy efficiency of the process chain is 73%. Tailored processes aiming at improved heat and mass integration as well as novel synthesis routes leading to reduced process complexity or avoiding oxidative intermediate steps hold significant promise for future efficiency improvements.
