新型高效低耗CO2捕集配方溶剂的开发及工业应用

摘要

结合工业装置流程及实际运行，采用连续吸收再生模试装置，研究了醇胺分子中氨基取代基以及空间位阻效应对烟道气中CO2捕集效果的影响。从分子结构的角度，开发了新型高效低耗CO2捕集配方溶剂，通过3～5 m3/h CO2捕集模试装置，考察了其捕集率与再生能耗的关系，并在胜利电厂和四川维尼纶厂进行工业应用。结果表明，与传统的一乙醇胺（MEA）法相比，该溶剂再生能耗降低30%。%The effects of amino substituents and steric hindrance on the capture efficiency of CO2 from flue gaswere investigated by means of a continuous absorption and regeneration device in combination with the industrial process and practical operation. A new type of high efficiency and low consumption CO2 capture solvent was developed based on the molecular structure. The relationship between the capture rate and regeneration energy consumption was investigated by means of 3-5 m3/h CO2 capture device. In addition, the solvent was successfully applied in Plants. The results showed that the regenerative energy consumption was reduced by 30% compared with the traditional monoethanolamine (MEA) method.
