Intensified Unit Operations and Lightweight Plant Design for Mobile Waste-to-Energy Systems

Diversified Energy proposes an innovative gasification system for the conversion of military useful waste streams into valuable energy products. The gasifier utilizes a molten bath, allowing for the gasification of a wide range of hydrocarbon feedstocks (e.g., biomass, MSW, sewage sludge, etc.) into a clean syngas free of oils and tars. The coupling of this technology, plus an intermediate gas clean-up system, along with a variety of syngas processing technologies (electricity, fuels, etc.) results in a fully integrated waste-to-energy architecture that is modular, transportable, and can meet OSD weight per barrel-day goals. In this 24-month effort the Diversified Energy team will conduct lab-scale and prototype hardware demonstrations of the key gasification system components. A gasifier will be built and tested using two different types of military useful waste feedstock. Syngas generated will be analyzed and the required downstream gas clean-up components will be defined. Analysis will also be conducted to assess the feasibility of integrating the gasifier with a variety of syngas processing technologies. The Phase II effort therefore maximizes hardware testing and builds upon Phase I results.
