摘要

The removal of CO sub 2 from air was investigated by using a continuous-agitated-slurry carbonation reactor containing either barium hydroxide (Ba(OH) sub 2 ) or calcium hydroxide (Ca(OH) sub 2 ). Such a process would be applied to scrub exp 14 CO sub 2 from stack gases at nuclear-fuel reprocessing plants. Decontamination factors were characterized for reactor conditions which could alter hydrodynamic behavior. An attempt was made to characterize reactor performance with models assuming both plug flow and various degrees of backmixing in the gas phase. The Ba(OH) sub 2 slurry enabled increased conversion, but apparently the process was controlled under some conditions by phenomena differing from those observed for carbonation by Ca(OH) sub 2 . Overall reaction mechanisms are postulated. (ERA citation 05:030276)
