Abstract: In order to absorb the CO2 in coal-fired flue gas, semi-continuous experimental studies for CO2 capture using chemical method were carried out with bubbling column reactor. According to the orthogonal experiment and the calculation of the removal rate, the research focused on the effect of absorbent type, gas temperature, flow rate, CO2 content, liquid level and absorbent concentration on the CO2 absorption. The results showed that the ammonia is one of the best absorbent, and the impact of the gas temperature is minimal. The influences of ammonia concentration, liquid level, flow rate and CO2 concentration on removal rate, absorption capacity and absorption rate are obtained by single factor experiments using ammonia solution.

Key words: bubble column reactor, orthogonal experiment, single factor experiment, carbon dioxide, absorption
