Project Funded In Part By The United States Department of Energy
LEHIGH VALLEY, Pa., March 9 /PRNewswire-FirstCall/ -- Air Products
(NYSE: APD) today announced the signing of a Cooperative Agreement
with the U.S. Department of Energy (DOE) to design and construct a
carbon dioxide (CO2) purification system in support of an oxyfuel
technology development project. The project, being conducted in
association with a separate Cooperative Agreement between DOE and
Alstom Power, Inc., will use Alstom's boiler simulation facility in
Windsor, Connecticut. CO2 purification is essential to the
compression, transport and potential sequestration of greenhouse
gas emissions from power plants. The development project at the 15
megawatt thermal equivalent facility, to be conducted over two
years beginning in mid-2009, is part of DOE's furthering
development of new and cost-effective technologies for the capture
of CO2 from the existing fleet of U.S. coal-fired power plants. In
the project, Air Products will purify a portion of the CO2 from
flue gas, or waste gas, coming from Alstom's tangentially-fired
(T-fired) coal combustion unit operated in oxy-combustion mode.
T-fired boilers are the most prevalent pulverized boilers used to
burn coal and make steam at coal-fired power plants, and make up
over 40 percent of the installed base of utility boilers in the
U.S. and around the world. Air Products' technology is designed to
purify the CO2 by targeting removal of up to 95 percent of the
impurities in the waste gas including sulfur oxides (SOx), hydrogen
chloride, and nitrogen oxides (NOx). These acidic impurities must
be removed from the CO2 stream to prevent corrosion before the
purified CO2 is introduced into a pipeline. Air Products' CO2
purification and compression system is targeted to achieve over 90
percent CO2 capture, while improving cost savings over other
technology such as amine-scrubbing, or more expensive and complex
flue gas de-sulfurization units and de-NOx units. "It's now time to
advance the technology from study and bench level testing to the
next scale evaluation. Air Products' oxyfuel technology has
optimized the compression process to remove impurities to an
acceptable level in the gas to make carbon sequestration possible.
The ability to achieve this at lower costs is encouraging to
industries with large scale CO2 emissions. We look forward to the
results of this project and applaud DOE for its dedicated efforts
on this important technology," said Steve Carney, business
development manager at Air Products. This project is part of DOE's
Office of Fossil Energy's Existing Plants - Emissions & Capture
program (EPEC), which is managed by the National Energy Technology
Laboratory. The EPEC program maintains a portfolio of research
projects to address these and other environmental challenges faced
by America's existing fleet of coal-fired power plants. Air
Products' oxyfuel technology can reduce the cost of capturing CO2
for the power industry. The company has specifically focused on the
purification of the resulting oxyfuel combustion flue gas,
developing a robust process for the efficient removal of trace
impurities. Air Products' proprietary sour compression technology
uses a staged compression process to optimize pressure, hold-up,
and residence time to allow removal of impurities during the
compression process. This allows cost savings in the oxyfuel
combustion process and minimizes the content of these components in
the sequestered CO2. For more information on Air Products' CO2 and
