design basis

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

design basis1

Design Basis

Newton County Landfill

265 Acres

Room for expansion

Access to MSW of South Chicago

Transportation

No river access

dioxins
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

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

eddy current separator
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

magnetic separator
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
