Modelling and Environmental Aspects of Direct or Indirect Dimethyl Ether Synthesis Using Digestate as Feedstock

The conversion of waste and residues towards high added value products has receiving a growing attention, as reliable strategy to improve sustainability emergent processes. Anaerobic digestion converts organic into biogas digestate. While may be used for energetic purpose, digestate limited uses with low profitability. In this paper, dimethyl ether (DME) is adopted target product which produced from digestate-derived syngas. Process simulation carried out both direct indirect synthesis DME environmental aspects are assessed.
