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.

[ES] La presente invención se encuadra dentro del campo de obtención de energía a partir combustibles carbonosos con captura de dióxido de carbono para su uso o almacenamiento permanente y en concreto se refiere a dispositivos y procedimientos que hacen posible la captura mejorada de CO2 mediante CaO en procesos de calcinación-carbonatación debido al uso de un recarbonatador donde se pone en contacto a los sólidos parcialmente carbonatados provemientes del carbonatador con CO2 altamente concentrado; de modo que la fraccion de carbonato en los sólidos aumente ligeramente por encima de la capacidad de captura efectiva de CO2 en el carbonatador y dicho aumento compense la pérdida de capacidad de captura de CO2 que experimentan dichos sólidos en el siguiente ciclo de calcinación-carbonatación, frenando así el proceso de desactivación en un valor de capacidad de captura de CO2 del sorbente más alto.
