본 논문에서는 저농도 CO2 조건에서 알카놀아민 흡수제 별 CO2 흡수 특성을 도출하였다. 단일흡수제의 경우 MEA농도가 1 wt%, 2 wt%, 3 wt% 증가 시 CO2 흡수량은 0.34 mol-CO2/mol-absorbent, 0.32 mol-CO2/mol-absorbent, 0.30 mol-CO2/mol-absorbent로 감소하였고, AMP 농도가 1 wt%, 2 wt%, 3 wt% 증가 시 CO2 흡수량은 0.32 mol-CO2/mol-absorbent, 0.30 mol-CO2/mol-absorbent, 0.28 mol-CO2/mol-absorbent로 감소하였다. 혼합흡수제의 경우 MEA 0.5 wt%와 AMP 0.5 wt%을 혼합했을 때0.52 mol-CO2/mol-absorbent로 최대치를 나타냈다. In this paper, absorption and reaction characteristics of low CO2 and alkanolamines were investigated. As MEA concentrationsincrease 1, 2 and 3 wt%, CO2 loadings decrease 0.34 mol-CO2/mol-absorbent, 0.32 mol-CO2/mol-absorbent and 0.3mol-CO2/mol-absorbent, respectively. Also, CO2 loadings decrease from 0.32 mol-CO2/mol-absorbent, 0.30 mol-CO2/mol-absorbentand 0.28 mol-CO2/mol-absorbent as AMP concentrations increase 1, 2 and 3 wt%. Experimental results with blending solutionsshow that CO2 loading was the highest, 0.52 mol-CO2/mol-absorbent, when 0.5 wt% MEA and 0.5 wt% AMP were blended. KCI Citation Count: 0
