CO{sub 2} for ocean disposal research
- Krebs and Sisler, Winnetka, IL (United States)
Closed single cycle O{sub 2}/CO{sub 2} combustion integrated with a unified cleaning system is proposed to produce a continuous supply of carbon dioxide for deep-sea sequestering research on the Island of Hawaii. It has been suggested that the quantity needed for injection might be about 100 tons per day, compressed to the appropriate pressure and then transported by a pipeline to an ocean depth of 2,000 feet or more and dispersed. This research project is so far only partly defined but likely will be run for a period of years, perhaps five or ten years or longer, in order to assure the viability of this method of CO{sub 2} disposal. The closed cycle plant with its required cryogenic air separation unit (ASU) can produce an approximately 98% CO{sub 2} exhaust gas byproduct, likely suitable for ocean disposal research without further processing, while producing electric power for distribution. A range of liquefied gases might also be recovered for export. This would be the first commercial scale demonstration of the O{sub 2}/CO{sub 2} combustion method with a projected net plant thermal efficiency improvement, so far as is known.
