【摘要】 采用搅拌实验装置,研究不同配比的环丁砜-DEA复合溶液对烟道气中二氧化碳的吸收和解吸性能,揭示了吸收速率、吸收容量与酸碱度、时间之间的内在联系,并对CO2初始逸出温度、试液再生温度、试液再生率、再生pH下降率进行了细致记录分析.实验结果表明:环丁砜-DEA复合溶液配比为0.1 0.9时:吸收效果最佳,吸收量约为0.253 mol;再生温度最低,约为102.2℃,再生率为87.17%.实验结果也说明该复合体系之间存在负的交互作用.更多还原

【Abstract】 A set of Stirring experiment was used to study the capability of absorption and desorption of carbon dioxide from flue gas with Sulfolane-DEA complex solution.The study revealed the releationship between absorption rate,absorption capacity,pH and time.Meanwhile,the data was recorded and analyzed,including the initial escape temperature of CO2,regeneration temperature,regeneration rate,and pH decline rate in regeneration.Experimental results showed that the absorption effect was the best in which the absorption capacity was 0.253 mol,when binary complex system SulfolaneDEA was 0.60.4.The highest regeneration rate was about 87.17% at the lowest regeneration temperature 106 ℃.The results also showed the negative interaction between potassium carbonate and TETA solution existed.更多还原
