    Novel Lime Calcination System For Co2 Capture And Its

    In conventional lime calcination processes, because of fuel combustion in the kiln, the carbon dioxide CO2 from limestone decomposition is mixed with the flue gas, which results in energy requirement for gas separation in the carbon capture process. Here, a novel lime calcination system with carrier gas CO2 heating and air cooling is proposed to avoid the mixing problem of the CO2 and the ...
