dc.description.abstract | The utilization of carbon dioxide to create valuable products such as methanol shows promise for addressing the issue of carbon emissions and global warming. Concurrently, it provides a solution to the intermittency and security of renewable energy supply via the water-splitting hydrogen production process. This power-to-methanol concept has gained increased attention because methanol is a liquid that can be conveniently stored and transported under ambient conditions. While direct air capture is an expensive solution, the carbon dioxide readily available from biogas can serve as a win-win situation. Similarly, water electrolysis technologies have modular, operational, and production challenges. In the present study, carbon dioxide was sourced from biogas via membrane separation, whereas H-2 was produced using plasma electrolysis. The entire power-to-methanol scenario was simulated using Aspen Plus v11. High purity and recovery of carbon dioxide and methane (99.51 mol.% and 98.29% and 98.88 mol.% and 99.68%, respectively) were achieved via membrane separation. The plasma reactor supplied H-2 with a mass yield of similar to 50%. Pure methanol (99.97%) was produced with a perpass conversion of 19.91% (15.7% higher than the base case). A detailed exergy analysis was performed on the process, highlighting the losses in heaters, separators, and reactors. Subsequent heat integration resulted in energy savings of 6.6%, while wind power as an energy source yielded carbon-neutral emissions. This conceptual study showcases the tremendous potential of the concept of zero-carbon-emission methanol production. | - |
