英文摘要	This work presents a case study on the first large-scale industrial biogas upgrading process with simultaneous purification of methane and CO 2 in one of Europe's largest biogas production and purification plants in Northern Italy. A preliminary study was performed on a pilot plant, constructed as a model of the industrial plant where the final experiments were performed. The full-scale anaerobic digestion plant has a digestive capacity of 400000 tonnes of biomass per year and it can treat 6250 m 3 h -1 of biogas. The first objective was a biogas upgrading process that achieves distribution grid-quality methane via different purification steps. The second objective and most innovative aspect is the further purification of CO 2 from a useless waste product to a high purity gas for the food and beverage industry. The chemical purity of different process streams was analysed by a certified laboratory and was compared with the guidelines of the European Industrial Gas Association and International Society of Beverage Technologists (EIGA/ISBT) for CO 2 used in the food industry. The microbiological purity was found to be far below the limit values defined in the European Collaborative Action. With a purity of 96.3 vol%, methane respects the purity requirement for the household network. With a purity of 98.1 vol% before, and 99.9 vol% after the final distillation process, CO 2 proves to be chemically and microbiologically suitable for food applications, thus closing the CO 2 loop in biogas production. An evaluation of the economic and energetic aspects and a comparison with alternative purification processes highlights the profitability of the process. © 2019 The Royal Society of Chemistry.
