“…The green degree of IL as a solvent is relatively high due to no loss of vented gas in the environment, CO 2 purity of above 90 %, and less energy consumption making it a benign environment choice. Xie et al [72] evaluated the performance of different IL types for the conceptual biogas upgrading. The results in Tab.…”

“…8). Xie et al [24] and Ma et al [26] both showed that DES based on choline chloride seems to be a promising candidate for biogas upgrading with the ability to save 35 % electricity cost and it needs less operational and capital cost with high recovery and purity of CH 4 . Haider et al [68] further evaluated the performance of pure ChCl/urea and aqueous ChCl/urea at an elevated pressure of 36 bar resulting in 99 % purity of biomethane.…”

Biogas requires specific processing in terms of upgradation to remove acid gas contents, making it a profitable fuel with higher energy content. This is conventionally attained through physical or chemical absorption due to the higher selectivity towards CO2 and H2S. The conventional processing technology impacts the process with higher energy content for solvent regeneration, solvent loss causing a threat to the environment with its toxicity, and damaging the equipment by corrosion. In this view, ionic liquids (ILs) emerged as potential candidates providing a favorable facet in terms of both processing and ecological aspects. Hence, herein the potential of IL and deep eutectic solvent (DES) in comparison to the conventional solvents and technologies used for biogas upgrading based on process system engineering perspective that showcases techno‐economic, energy‐economic, and environmental aspects and opportunities that may lead towards establishing sustainable and effective processing of biogas is shown and a comprehensive review on the opportunities, prospects, and challenges to make IL and DES as future solvent for biogas upgrading on the commercial scale is provided.

“…In recent years AD of MSW has become popular all over the world. Case studies have been described in Mexico, 17 The Netherlands, 18 Scandinavia, 19 South Africa, 20 Indonesia, 21 Australia, Italy and Spain 22 and Brazil, 14 to name just a few recent examples. The majority of MSW is generated by households (55–80%), while only a small portion is generated by commercial or market areas (10–30%).…”

BACKGROUND Biogas is a valuable carbon‐free renewable energy source that can be produced from anaerobic digestion of organic waste. Accordingly, biogas production is promoted worldwide in efforts to reduce carbon emissions and optimize the recovery of resources from waste streams. In this paper the biogas production from bioresidues collected in the capital area of Reykjavik was modelled in Aspen Plus v10. RESULTS Municipal solid waste (MSW), food waste (FW) and lignocellulosic biomass (LCB) were the feedstocks used in this research. A total of 16 scenarios were simulated at thermophilic temperature conditions of 55 °C. Each scenario accounted for different inlet mass flows, varying the kind of feedstock, i.e. MSW, FW, LCB, or co‐digestion of various feedstocks, using two model approaches: (i) one digestion stage and (ii) two stages coupled in series. Sizing, costing and environmental aspects were analysed for all the scenarios. A sensitivity analysis was carried out by changing the substrate concentration and studying its effect on the methane mass flow. Simulations showed biogas yields measured in millilitres per gram of volatile solids (VS) in the range 305.5–406.4 mL g−1 VS (single‐stage approach); and biogas yields ranging from 64.78 to 358.8 mL g−1 VS (two‐stage approach). Maximum methane yields were obtained using LCB as feedstock resulting in 106.0 mL g−1 VS. CONCLUSIONS From a technical viewpoint the highest biogas yield is obtained when using MSW whereas optimum calorific value of biogas and electrical power potential is achieved working in co‐digestion of various feedstocks. © 2020 Society of Chemical Industry
