PROCESS FOR DECARBONATION OF CARBONATED MATERIALS AND HYDRATION THEREOF AND DEVICE THEREOF
Process for decarbonation of limestone, dolomite or other carbonated materials and hydration of said decarbonated limestone, dolomite or other carbonated materials, said process comprising the following steps: heating particles of carbonated materials (6) in a reactor (8) of a first circuit (2); conveying said particles of carbonated materials (6) by a first entraining gas (4); transferring the decarbonated particles (16) to a second circuit (12), in which a second gas (14) circulates, said circuit (12) comprising a hydration section (23). hydrating the decarbonated particles (16); transferring at least a portion of the heat generated by the hydration of the decarbonated particles (16) to the second gas (14) being substantially free of carbon dioxide; wherein the first (2) and second circuits (12) are separated by first selective separation means (20) allowing the passage of solids while substantially preventing the passage of the gases (4, 14).
