Title: Experimental Study on Absorption of CO_2 from Flue Gas by K_2CO_3-MEA Composite Solution
Abstract: Using different concentrations of K2CO3 solution and different proportion of K2CO3-MEA composite solution as absorber,absorption rate and absorption capacity as indexes,the effects of absorber on absorption efficiency of CO2 from flue gas were investigated.The results showed that absorption efficiency of pure K2CO3 solution was not good,but significantly improved by the incorporation of MEA,even part of the composite solution exhibited better absorption efficiency than the same concentration of pure K2CO3 solution plus pure MEA solution.Using 0.6 mol·L-1K2CO3-0.4 mol·L-1 MEA as absorber,the saturated absorption capacity was the most(0.185 mol),the regeneration temperature was the lowest(105 ℃) and the regeneration rate was the highest(98.8%).
