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

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

  • Alternate Materials

    • Mining waste

    • Potliner waste

    • Cyanide waste

    • Fly ash

    • Slag

  • Tires

    • An alternative fuel

    • For NOx reduction

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


Co2 emissions from cement kilns l.jpg
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

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

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


Cement industry environmental consortium11 l.jpg
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


Cement industry environmental consortium12 l.jpg
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!

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

  • 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

  • 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

  • Temperature Swing Adsorption

  • Regenerating adsorbent

  • Inlet temperature ± 200° C

  • Exit temperature ± 40 ° C

  • Moisture in exhaust may be an issue

  • CO2 recovery 90% +
