ENHANCED RECOVERY OF CARBON DIOXIDE FROM KILN GAS BY ADDITION OF COOLED CARBON DIOXIDE

摘要

RECOVERY OF CARBON DIOXIDE FROM KILN GAS High purity carbon dioxide-rich gas is produced from hot, carbon dioxide-rich kiln exhaust gas by cooling the exhaust gas by injecting carbon dioxide-rich gas, such as high purity carbon dioxide or previously cooled carbon dioxide-rich kiln exhaust gas into the exhaust gas to cool the gas, removing particulate impurities from the cooled exhaust gas and separating high purity carbon dioxide from the exhaust gas.
