Device and method for the capture of Co2 by CaO carbonation and for mantaining sorbent activity
[EN] The present invention is included within the field of energy production from carbonaceous fuels with capture of carbón dioxide for its use or permanent storage and in particular relates to devices and methods which enable the improved capture of C02 by CaO in calcination-carbonation processes due to the use of a recarbonator(l) where the partially carbonated solids from the carbonator(2) are brought into contad: with highly concentrated C02(13); so that the fraction of carbonate in the solids increases slightly above the effective C02 carrying capacity in the carbonator and said increase compensates the loss of effective. C02 carrying capacity that said solids undergo in the following calcination-carbonation cycle, thus checking the deactivation process in a higher valué of C02 carrying capacity of the sorbent.
