摘要
Capturing flue gases often require multiple stages of scrubbing, increasing the capital and operating costs. So far, no attempt has been made to study the absorption characteristics of all the three gases(NO, SO_(2) and CO_(2)) in a single stage absorption unit at alkaline p H conditions. We have attempted to capture all the three gases with a single wet scrubbing column. The absorption of all three gases with sodium carbonate solution promoted with oxidizers was investigated in a tall absorption column. The absorbance was found to be 100% for CO_(2), 30% for NO and 95% for SO_(2) respectively. The capture efficiency of sodium carbonate solution was increased by 40% for CO_(2) loading, with the addition of oxidizer. Absorption kinetics and reaction pathways of all the three gases were discussed individually in detail.
