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

Idem, R. ; Wilson, M. ; Tontiwachwuthikul, P. ; ... April 2006 - Industrial and Engineering Chemistry Research

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

Ellington, R.T. ; Achilladelis, B. ; Mueller, M.J. ; ... October 1984 - Oil Gas J.; (United States)

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

Chen, Shiaoguo September 2015

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 »« less
