Title: 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.
