Techno-economic study of CO{sub 2} capture from an existing cement plant using MEA scrubbing
Abstract
Carbon dioxide is the major greenhouse gas responsible for global warming. Man-made CO{sub 2} emissions contribute approximately 63% of greenhouse gases and the cement industry is responsible for approximately 5% of CO{sub 2} emissions emitting nearly 900 kg of CO{sub 2} per 1000 kg of cement. CO{sub 2} from a cement plant was captured and purified to 98% using the monoethanolamine (MEA) based absorption process. The capture cost was $51 per tonne of CO{sub 2} captured, representing approximately 90% of total cost. Steam was the main operating cost representing 39% of the total capture cost. Switching from coal to natural gas reduces CO{sub 2} emissions by about 18%. At normal load, about 36 MW of waste heat is available for recovery to satisfy the parasitic heat requirements of MEA process; however, it is very difficult to recover. 18 refs.

Pilot plant studies of the CO{sub 2} capture performance of aqueous MEA and mixed MEA/MDEA solvents at the University of Regina CO{sub 2} capture technology development plant and the Boundary Dam CO{sub 2} capture demonstration
Evaluations of the benefits of using a mixed MEA/MDEA solvent for CO{sub 2} capture in terms of the heat requirement for solvent regeneration, lean and rich loadings, CO{sub 2} production, and solvent stability were performed by comparing the performance of aqueous 5 kmol/m{sup 3} MEA with that of an aqueous 4:1 molar ratio MEA/MDEA blend of 5 kmol/ml total amine concentration as a function of the operating time. The tests were performed using two pilot CO{sub 2} capture plants of the International Test Centre for CO{sub 2} Capture (ITC), which provided two different sources and compositions of flue gas.

Scrubbing CO/sub 2/ from plant exhausts provides economic sources of gas for EOR projects
The impact of the combined-cycle/ CO/sub 2/ application on employment, income, and tax revenue could be significant. High efficiency power/steam generation in gas producing areas can compete strongly with other fuels and generate new revenue for these areas. The addition of CO/sub 2/ recovery for EOR in the area can add other new revenues directly, and indirectly from additional oil production. Further, energy system integration could provide strong arguments for greater usage intrastate. -
DEVELOPMENT OF A NOVEL GAS PRESSURIZED STRIPPING (GPS)-BASED TECHNOLOGY FOR CO 2 CAPTURE FROM POST-COMBUSTION FLUE GASES Topical Report: Techno-Economic Analysis of GPS-based Technology for CO 2 Capture
This topical report presents the techno-economic analysis, conducted by Carbon Capture Scientific, LLC (CCS) and Nexant, for a nominal 550 MWe supercritical pulverized coal (PC) power plant utilizing CCS patented Gas Pressurized Stripping (GPS) technology for post-combustion carbon capture (PCC). Illinois No. 6 coal is used as fuel. Because of the difference in performance between the GPS-based PCC and the MEA-based CO2 absorption technology, the net power output of this plant is not exactly 550 MWe. DOE/NETL Case 11 supercritical PC plant without CO2 capture and Case 12 supercritical PC plant with benchmark MEA-based CO2 capture are chosen as references.more »
