【摘要】 化学溶液法脱除CO2 是工业中一项传统的净化气体的方法。DEA是目前回收烟道气中低浓度CO2 所使用的最主要试剂,本实验进行DEA吸收CO2 的实验,掌握了溶液pH值与CO2 浓度变化的情况,并用这一方法进行测定CO2 浓度的研究。通过考察溶液的再生情况,了解再生温度对溶液再生效果的影响。更多还原

【Abstract】 The scrubbing of CO₂ by solvent is a traditional process for gas purification. DEA is currently the primary reagent for the recovery of low-concentration CO₂ of fuel. In this paper, we performed experiments of CO₂ absorption by DEA, received the corresponding relationships between the pH value of solvent and the concentration of CO₂, and investigated the determination of CO₂ concentration by means of this method. We also studied the regeneration of solvent and probed into the influence of temperature on the effect during regeneration.更多还原
