Abstract
The present study involved an in-depth simulation and evaluation of a 10 MWth food waste chemical looping gasification to hydrogen system, conducted using Aspen Plus process simulation software. The study extensively investigated process optimization, economic evaluation, and the environmental impacts associated with the application of this technology. The simulation results showed that maintaining a fuel reactor temperature at 850°C, an H2O/C ratio of 0.6, and an O/C of 0.45 yielded an H2/CO of 1.718, Y of 1.209 m3/kg, and CEG of 51.78 %. Life cycle assessment indicated favorable outcomes concerning environmental impacts. Particularly, the system operational in the Qingdao region showed a global warming potential of 1763.5 kgCO2-eq and an acidification potential of 16.77 kgSO2-eq. Economic analysis revealed that the system offers substantial economic benefits with a return on investment of 11.23 %, a payback period of 6.283 years, and a net present value of 1.201 × 106 $. The cost of this process significantly undercuts that of renewable hydrogen production, providing considerable environmental advantages by effectively utilizing waste resources and reducing waste disposal issues. Given its cost-effectiveness and environmental benefits, chemical looping gasification technology for hydrogen production from food waste holds wide-ranging future application potential.
期刊介绍：
The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice.
PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers.
PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
