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 &

 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

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


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




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 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

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% +

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

Cement Industry Environmental Consortium

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
