  1. Cement Industry Environmental Consortium Carbon Capture and Reuse Project http://www.cieconline.net

  2. Cement Industry Environmental Consortium • The CIEC is a non-profit corporation organized in 1985 • Members include cement companies, air districts, and utilities • Mission Statement is to: a. undertake research relating to environmental issues affecting the cement manufacture and supporting industries; b. implement those developed technologies

  3. CIEC Research & Commercialization • Biosolids • NOx Reduction • Alternate Materials • Recorded values below 2 lbs NOX per ton of clinker • Cement Kiln Dust Utilization by Kiln • Reuse • Alternate product development • Reduction in generation rates

  4. CIEC Research & Commercialization • Alternate Materials • Mining waste • Potliner waste • Cyanide waste • Fly ash • Slag • Tires • An alternative fuel • For NOx reduction

  5. Cement Industry Environmental Consortium California Cement and CO2 • California largest producer of cement in US • California largest importer of cement in US • Most cement companies foreign owned • Average plant produces 1 million tons cement/yr (11plants producing 13 M tons) • Each ton of cement produces 1 ton CO2 • 40% CO2 from fuel 60% from chemistry

  6. CO2 Emissions from Cement Kilns • Cement consumption projected to grow, so CO2 output will grow • No concrete without Portland Cement • Approximately 15% cement in concrete • Plants need to be located at mineral sources • Today California’s cement demand is very high, creating unprecedented delays in construction

  7. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • Potential project identified in 2001 • Initial evaluation by Technology Committee indicated possible reuse applications for recovered CO2 – Oil fields and fertilizers • Current amine recovery systems determined to too small with recovery too costly plus capital on order of 100 million dollars

  8. Cement Industry Environmental Consortium • ABB Picture of Oklahoma 200 ton/day CO2 extraction plant • From “Learning Our Way To Zero Emissions Technologies Zero Emissions Technologies” Edward S. Rubin Department of Engineering and Public Policy Carnegie Mellon University Pittsburgh, Pennsylvania IEA Zero Emissions Technologies Strategies Workshop Washington, DC, March 19, 2002

  9. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • Potential for concurrent reduction of conventional pollutants if CO2 recovered • The CIEC received a $70,000 grant by the MDAQMD to undertake an initial solicitation, review of received proposals, and to develop additional funding sources

  10. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • CIEC members made a presentation to the ARB, with CEC staff present, soliciting funding • CIEC has attempted to identify funding sources from DOE (grants) • DOE has directed us to the Regional Partnerships • CIEC not opposed to request congressional funding

  11. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • The CIEC CO2 project differs from that of the Portland Cement Association Capture and reuse vs. fuel economy and admixtures • Very promising line of inquiry that doesn’t seem to fit available R&D funding “boxes”. A square peg in a world of round holes • We are still looking for funding!

  12. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • Response to the solicitation 37 specific projects received 25 proposal teams 7 proposals selected for interviews 2 recovery technologies selected 2 awards made for theory validation Temperature Swing Adsorption Enzymatic Recovery

  13. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • Generic Types of Responses Waste heat conversion to electric power Reduce emissions via plant audits Treatments for flue gas Change fuel or cement chemistry Conversion of CO2 to salable products

  14. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • Temperature Swing Adsorption Adsorption Research Inc. Kent Knaebel - Contact • Adsorbent used to capture CO2 • Temperature change releases CO2 • Cost of recovery estimated at < $10/ton

  15. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • Temperature Swing Adsorption • Regenerating adsorbent • Inlet temperature ± 200° C • Exit temperature ± 40 ° C • Moisture in exhaust may be an issue • CO2 recovery 90% +

  18. Cement Industry Environmental Consortium • Carbozyme Inc. Mike Trachtenberg - Contact • Enzyme both captures and releases CO2 • Modular units for project sizing and replacement • Cost of recovery estimated at $15/ton • CO2 concentration less an issue

  19. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • Enzymatic Recovery • Enzyme temperature limited (40 –50° C) with potential of 85 ° C. • Life cycle of membrane/enzyme affected by NOx and SOx in system

  20. Vacuum System Water Separator Sweep Heater Feed Cooler Economizer Heater Gas from Blower Carbozyme Reactor Air/Water Separator CO2 Cooler Pump Cement Industry Environmental Consortium Scrubbed Air Carbon Dioxide Water

  21. Cement Industry Environmental Consortium

  22. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • CIEC member plants available for commercial demonstration • Location of demonstration based on reuse option and volumes CO2 to be recovered • Target project size of 5 tons/day of CO2

  23. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • Status of theoretical validation contracts • ADI currently testing bench scale unit using a modeled air stream at operating temperatures • Carbozyme doing enzyme degradation tests with modeled flue gas

  24. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • Completion of Validation testing completed by November 15, 2004

  25. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • Continuing to look at CO2 reuse options • Starting evaluation of liquefying and/or compressing CO2 • Lobbying for PUC changes in recovered heat systems

  26. Cement Industry Environmental Consortium Carbon Capture and Reuse Project • We are still looking for funding!! http://www.cieconline.net
