The operation of calcination carbonation technology is based on the ease of co2 reaction with calcium oxide (CaO) to produce limestone powder (CaCO3). To start the process, this plant has two interconnected reactors, a carbonator and a calcinator, operating at atmospheric pressure and in a temperature range of 650 - 700oC and 850 - 950oC respectively. During the process, the CO2 (carbon dioxide) produced in the combustion of biomass within the carbonator reacts with the lime (CaO, calcium oxide) contributed to combustion by trapping the CO2 in the form of CaCO3 (calcium carbonate), so the smoke coming out of the reactor does not contain CO2. The process is completed with a second cycle that takes place in the calcinator. Here the CaCO3 obtained in the carbonator is introduced to transform it again, by means of heat input, into CaO that will enter the carbonator repeating the cycle.
