Now days, reducing the CO2 emission have become increasingly emphasized as a primary environmental concern. There are some methods to sequester the CO2 emitted, one of them is mineral carbonation. In mineral carbonation, CO2 is reacted with minerals to form solid carbonates. Of the existing research studies examining mineral carbonation, most have focused on the use of mined mineral rock as feedstock. Industrial solid wastes and residues, however, may provide the alternative mineral sources. This research focused to study potency the utilization of the carbide lime by product in mineral carbonation process. The experiment resulted that the CO2 removal increased with increasing mass addition of carbide lime by product and the gas flow rate, meanwhile the present of undissolved carbide lime by product in slurry form inhibited the carbonation process. From the determination of overall liquid phase volumetric mass transfer coefficient (Kla) value, Kla increased with increasing mass addition of carbide lime by product and the gas flow rate. The present of undissolved carbide lime by product in slurry form inhibited the mass transfer process which lead to decreasing the Kla value.
