Feasibility Assessment of Using Refuse Derived Fuel as an Energy Source of the Multi-Effect Desalination with Thermal Vapor Compression of Seawater Desalination System

In arid regions grappling with severe water scarcity, seawater desalination emerges as a pivotal solution. This research focuses on Bandar Abbas, Iran, specifically chosen for its arid climate, residents' water consumption patterns contributing to municipal solid waste (MSW), and the associated environmental concerns linked to MSW disposal. The study explores Refuse Derived Fuel (RDF), derived from MSW, as a potential energy source for a Multi-Effect Desalination with Thermal Vapor Compression (MED–TVC) system. The feasibility of RDF production in Bandar Abbas is rigorously assessed through seven distinct cases. Within the examination of these cases, the most favorable outcome highlights the optimal performance of RDF integration, demonstrating its potential to effectively alleviate water scarcity, address environmental issues, and yield economic advantages in arid regions. The findings indicate that ۴۰ tons of RDF can efficiently generate motive steam, resulting in a maximum distillate output of ۳,۷۲۱ m³/d. Projections suggest annual benefits reaching up to ۳,۳۵۲,۸۵۴ USD/year, coupled with a significant ۲۴% reduction in landfill utilization and the separation of metals for reuse. These outcomes underscore the notable environmental benefits of the integrated system.
