| description | <p dir="ltr">Biogas is a promising renewable energy source that is produced from biowaste and can potentially replace conventional energy resources. The economic value of biogas, which is primarily comprised of CH<sub>4</sub>, CO<sub>2</sub>, and other impurities (e.g. H<sub>2</sub>S, and N<sub>2</sub>) can be increased by upgrading and purification. This study presents the techno-economic feasibility of the cryogenic biogas upgrading process (CBioUP) based on product purities, biomethane selling prices and different refrigeration systems over 25 years of lifetime. The proposed CBioUPs is comprised of compression, refrigeration, and separation sections. Compressed biogas was liquefied in two refrigeration systems (propane pre-cooled mixed refrigerants and optimized cascade technologies) followed by a distillation separation unit. CBioUP proved its flexibility in terms of the number of distillation columns to produce low-grade CH<sub>4</sub> (≈94.58 mol%), high-grade CH<sub>4</sub> (≈97.13 mol%), and liquid CO<sub>2</sub> by-product. The process's robustness to varying biogas feed composition revealed higher CO<sub>2</sub> content would necessitate additional duty and/or equipment to enhance separation efficiency, whereas a CH<sub>4</sub> content of ≥70% generated biomethane with a purity >99.6 mol% even in a single distillation column. CBioUP demonstrated its suitability for producing different grades of CH<sub>4</sub> with a promising net present value (NPV) of $28.3 and $30.9 billion for low/high-grade biomethane.</p><h2>Other Information</h2><p dir="ltr">Published in: Energy<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.energy.2022.126163" target="_blank">https://dx.doi.org/10.1016/j.energy.2022.126163</a></p> |
