Transcript

  • 1. Pyrolysis R&D Presentation EcoMonday Meeting February 2, 2009 Timothy McDonald PE, MBA
  • 2. The Issues
    • Green House Gases - Nitric Oxide, Methane, CO2
    • Climate change impact on food, water, temperatures
    • Nitrate pollution of aquifers (fertilizers / manure)
    • Forests - drought, beetles, fire, thinning projects and management costs
    • Farms – waste, water, fertilizer and fuel
    • Municipalities - water, green wastes, sewage sludge
    • Farm and forest “Burn Pile” emissions
    • ACC Renewable Mandate to regulated electric utilities
    • CO2 Emissions Reduction Credits (future carbon tax)
    • Fuel availability and costs
  • 3. Arizona Forests
  • 4. Arizona CAFOs – Manure
    • ~ 168 CAFO farm sites
    • ~ 600,000 cows & pigs
    • ~ 3,600,000 chickens
    • Manure is a limiting factor on operations
    • Also a community issue
  • 5. Arizona Biomass Summary
    • Forest and woodland waste
      • 12 Million acres of forest and woodlands
      • 350,000 acres managed per year
      • 4.5 Million tons per year of waste
    • Agriculture waste
      • Cotton gin trash, orchard residue, straw
      • 200,000 tons of material per year
    • Urban green waste
      • Primarily from Phoenix and Tucson
      • 95,000 tons per year
  • 6. Biomass Disposal Options
    • Composting
    • Incineration / Landfill(?)
    • Aerobic / Anaerobic digestion (wet slurries)
    • Biomass derived pellets / briquettes
    • Direct combustion (ABITIBI biomass power plant)
    • Gasification (dried and chipped biomass)
    • Co-firing in utility power plants (charcoal / biooil)
    • Pyrolysis conversion (syngas, oils, char)
  • 7. Biomass Conversion Issues
    • Pre-processing and hauling costs
    • Air, Water and Solid Waste permits
    • Economies of scale w/ 50 mile radius fuel supply
    • Biomass waste materials have no intrinsic value
    • Waste biomass is typically just burned
    • Renewable power plant water and waste disposal
    • Renewable plant reliability and interconnection
    • Pyrolytic oil acidity and shelf-life stability
  • 8. Cholla Biomass Co-Firing Analysis
  • 9. 50 Mile Radius for Potential Biomass Sites Ashfork Casa Grande Eagar Flagstaff Gila Bend Heber Prescott Phoenix Metro San Carlos Snow Flake Stanfield Tucson Tusayan Whiteriver Wilcox Window Rock Yuma ABITIBI
  • 10. Intro to Portable Pyrolysis Concept
    • Portable system is moved to biomass location
    • Owned / operated by farm Co-ops, Communities, and/or individual company(s)
    • Convert zero value waste biomass into higher value liquid / solid feedstock materials
    • Stabilize oils for easier handling and processing
    • Char and oils shipped to centralized refinery(s)
    • Initial products: fertilizer supplement; oil for coal-dust suppression; solids for co-firing w/ coal
  • 11. ½ TPD Portable Pyrolysis System
  • 12. Pyrolysis System Feedstocks
    • Sweet sorghum
    • Nut shells
    • Cotton harvest debris
    • Orchard debris
    • Salt cedar
    • Mesquite
    • Manures
    • Pinion and juniper
    • Small-diameter pines
    • Municipal tree trimming green wastes…..

  • 14. Pyrolysis Oil
    • Dark brown viscous liquid
    • Strong smoky odor
    • Corrosive with acidic ph
    • Polymerizes into solid if reheated
    • Phase separation in container
    • “ A” Phase: water & acids
      • Organic acids for fertilizer
    • “ B” Phase: cellulosic oils
      • Phenols suitable for fuels and chemicals
    • “ C” Phase: hemi-cellulosic oils
      • Fuel and chemical feedstock
    • “ D” Phase: lignin oils w/ char dust
      • Polymerize into solid fuel
      • Binder for char granules / pellets (?)
      • Gasified for F-T into diesel fuel
    “ A” Phase ~15% “ B” and “C” Phases ~50% “ D” Phase ~35%
  • 15. Pyrolysis Char
    • Charcoal powder
    • Contains inorganic minerals from biomass
    • Some oils from pyrolysis
    • Form granules or pellets using “D” lignin-oil binder
    • Co-fire pellets w/ coal
    • Gasification - FT - Diesel
    • Activated carbon filters (water, power plant stack)
    • Time-released nutrients
    • Basis for “Terra Preta” soil
  • 16. Bio-Refinery
    • Centralized location(s)
    • Multiple biomass sources within 200 mile region

    • Terra Preta soil is still active and viable
    • Better crops than with chemical fertilizers
    • Less water and fertilizer per crop cycle!!
    • Soil can be “harvested” – will “regrow”!!
    • Scientists not sure how Terra Preta made
  • 20. Pyrolysis Project Vision/Objectives
    • Carbon sequestration: CO2 credits
    • Meet ACC Renewables Mandate w/ biomass co-firing
    • New sources of biomass-based sustainable fuels
    • Rural economic development opportunities
    • Forest fuel thinning projects w/o subsidiary payments
    • Conversion of farm wastes into revenues
    • Reduce water and fertilizers needed per crop cycle
    • Squeeze every nickel of value out of waste biomass
    • Help resolve WATER / ENERGY / POLLUTION issues
