Carbon Management Technology Conference,
7-9 February 2012,
Orlando, Florida, USA
The Clean Energy and Fuel Company (CEFCO) Process is a newly patented
aerodynamic approach to CO2 and multi-pollutant capture, based on "supersonic
free-jet collision scrubbing", employing low-cost shockwaves. CO2, is targeted
for removal at 90% efficiency and SO2, NOx, & Hg and other trace metals,
particulates (including below 2.5 microns) at 99% removal efficiency. It should
be recognized as Utility MACT (“Maximum Achievable Control Technology”)
compliant for the Power Industry in the upcoming years.
CEFCO Process for CO2 capture is —
1) An energy-efficient and “profit-making" process versus the currently
developed high "energy penalty" CO2 capture cost-centers.
2) Produces valuable multiple end-products in addition to CO2 versus the
current uneconomic processes.
3) MACT-compliant technology significantly minimizes water and energy
consumption compared to the current BACT (“Best Available Control Technology”)
For most amine-based Post-Combustion CO2 capture technologies to function
effectively they will require the incoming flue gas to be treated containing
less than 5 ppm of NOx and 10 ppm of SO2, at levels difficult to achieve
continuously, even with integration of multiple-overlapping thermo-chemistry
based technologies. Although work on reduction of energy penalty is under way ,
the “energy penalty” of around 33% on performance and 22.7% auxiliary load on
net power sent out have been estimated on a nominal “best case” 800 MWe coal
fired power plant and have become conventional expectation of energy penalty in
any BACT process.
In contrast, the CEFCO aerodynamic reactor technology long adopted by the US
Department of Energy has been in use for radioactive waste incineration in the
USA and recognized by US EPA on May 22, 2002 as MACT compliant for Hazardous
Waste Combustion. That standard is much more stringent than the current Utility
MACT under consideration.
