  1. Ethanol Recycle Paper Converting Waste Paper into Ethanol March 28, 2008

  2. Outline • U.T.C. Engineering • Agricultural Comparison • Papernol Process • Hydrolysis • Fermentation • Purification • Equipment Sizing and Cost • Full Scale Outlook

  3. Distillation Intro Chemical Process Thermodynamics Engineering Economics Senior Papernol Project Freshman Design Process design Heat & Mass Transfer Reactor Design Unit Operations

  4. UTC Papernol Team - 2008

  5. How is Papernol Different?

  6. Papernol Advantages • Converts Waste Stream to Revenue Stream • Resource from Local Community • Improves Local Economy • Minimal Transportation/Fuel Inputs • No Cropland Requirement

  7. Acid Hydrolysis: Dilute acid to generate glucose from cellulose Fermentation: Convert Glucose into Ethanol Purification: Separate Ethanol from water Preparation and Hydrolysis Fermentation Purification

  8. Material Balances EtOH 500 gal/day PAPER 10,000 lb/day

  9. Preparation(Basis 10,000 lb paper/Day) 150,000 lb H2O 10,000 lb paper 160,000 lb slurry *8,000 lb cellulose* Research: 7% paper water mixture 80% paper is cellulose

  10. Hydrolysis (Basis 10,000 lb paper/Day) 1600 lb H2SO4acid(98%) 230 lb steam 62,000 lb steam 150,000 lb H2O *5600 lb glucose* 70% conversion 160,000 lbslurry 2,200 lb solid waste

  11. Evaporation - Fermentation (Basis 10,000 lb paper/Day) 2850 lb CO2 860 lb yeast 80,000 lb steam 330,000 lb CW 62,000 lb H2O *2850 lb EtOH* 150,000 lb H2O *5600 lb glucose* 62,000 lb H2O *5600 lb glucose*

  12. Purification (Basis 10,000 lb paper/Day) 2,800 lb EtOH 65,000 lb EtOH–H2O 500 gal EtOH 62,200 lb H2O

  13. Energy Balances QLOST = 49 million BTU/day QIN = 49 million BTU/day QPRODUCT = 38 million BTU/day QADDED = 210 million BTU/day

  14. Preparation Total Daily Electrical Energy ~6 MM BTU 4.5 MM BTU/day 41,000 BTU/day 1.5 MM BTU/day

  15. Hydrolysis QIN=185,000 BTU/day QIN=50 MM BTU/day QIN=13,000 BTU/day Total Daily Electrical Energy ~50.2 MM BTU

  16. Evaporation - Fermentation QOUT= 8 MM BTU/day QIN=94 MM BTU/day

  17. Purification QOUT= 41 MM BTU/day QIN= 66,000 BTU/day QIN=60 MM BTU/day QOUT= 223,000 BTU/day

  18. Example of Sizing • Evaporator: Fxf = Lxl xf = current concentration xl = desired concentration L = F(xf/xl) = Liquid Exit Stream L/ρH2O = Volume of Evaporator

  19. Equipment Size and Cost

  20. Equipment Size and Cost

  21. Stages of Project Development Lab Proof of Concept • Lab Scale – Proof of Concept • Currently in Progress at UTC • Available Budget: $500 • Restricted Testing Pilot Scale: 2009-2010 Integrated Processing Utilize TVA/UTC Chickamauga Site Estimated Budget: $1,000,000 Medium Scale: 2008-2009 Small Demonstration Budget: $150,000 Tested Using UTC ENGR Labs Medium Small Demonstration Pilot Integrated Processing Orange Grove: 2010-2011 Full Unit Skid-Mounted Modular Estimated budget: $3,000,000 Full Scale Unit Orange Grove Center

  22. Potential Orange Grove Site Process 10,000 lb Paper =500 gal of Ethanol per day => Three Tractor Trailers

  23. Current Work Toward our Preliminary Design: • Economics • Environmental Aspects • (CO2 foot print) • Utility Costs

  24. Papernol Outlook • Cannot resolve the US energy dilemma • Orange Grove = 500 gal/day max. • Adds value to Orange Grove • Competitive with Corn & Switchgrass • A Renewable Ethanol Source
