  1. “Garbage to Gas” Team Bravo EleftheriosAvtzis David Garcia Bryan Isles Zack Labaschin Alena Nguyen Mentor Dan Rusinak Che 397 - Team Bravo

  2. Design Basis • Commercial Scale Production • 12,000-14,000 tonnes per day MSW •  3,000+ tonnes per day Syngas • Ideal max. capacity 8,000+ tonnes per day • Scale-up available • Landfill choice confirmation • Location • Proximity to City • Water Sources • Size and expansion

  3. Engineering Specifications Che 397 - Team Bravo

  4. Design Basis Newton County Landfill 265 Acres Room for expansion Access to MSW of South Chicago Transportation No river access

  5. Methane Emissions in U.S.Top 5 Sources Che 397 - Team Bravo

  6. Dioxins • At 800-900°C, dioxins thermally decomposes • SynGas temp. through gas conditioning unit is raised to 1000°C • No copper: which promotes dioxin formation • Dioxins tend to adsorb on char and breakdown in the combustion reactor Che 397 - Team Bravo

  7. Carbon Footprint Environmentally friendly process by removing carbon waste from the environment. Che 397 - Team Bravo

  8. Block Flow Diagram Ash to landfill Recycled metals Sulfur Halogens Hazardous materials MSW Processing Gasifier Methane Reforming RDF Raw SynGas MSW Return to landfill Steam Electricity Steam Generation Cooling & Cleaning Electrical grid Clean SynGas CO2 Team Alpha Gasoline Production CO2 Removal Reverse Water-Gas Shift SynGas at spec. Che 397 - Team Bravo

  9. RDF Processing Che 397 - Team Bravo

  10. Shredding: Hammer Mill Che 397 - Team Bravo

  11. Trommel Screen • Cylinder with screen on the outside • Sorts shredded MSW by size • Rotates to drive the MSW through from one side to the other Che 397 - Team Bravo

  12. Eddy-Current Separator • Basic schematic of Eddy-Current Separator • Non-Ferrous metals are ejected • This is prior to removal of ferrous metals Che 397 - Team Bravo

  13. Magnetic Separator • For removal of Ferrous metals • Uses magnets to hold iron containing metals to the roller • Releases them into separate bin for return to landfill Che 397 - Team Bravo

  14. TBE Process SynGas SynGas Tars Gas Conditioning Reactor Flue Gas Olivine (Hot) Combustion Reactor Gasifier RDF Air Olivine Steam Char, Ash & Olivine (Cool) Ash Removal Che 397 - Team Bravo
