Abstract: This paper focuses on ammonia evaporation in ammonia-based CO2 capture. Based on our previous research, glycerol and Co(Ⅱ) with promising effect on controlling ammonia escape were studied. The mechanisms of controlling ammonia escape using glycerol and Co(Ⅱ) were analyzed with IR, UV, XRD and the impact on CO2 removal and desorption was investigated. Both glycerol and Co(Ⅱ) could control ammonia escape with average efficiency of above 40%. Glycerol and Co(Ⅱ) had no significant effect on absorption of carbon dioxide, while Co(Ⅱ) could promote desorption of CO2.

Key words: CO2 capture, ammonia method, evaporation, control

摘要: 本研究致力于解决再生氨法碳捕集过程中氨的逃逸问题。根据实验室前期研究结果,分别选取抑制效果较好的丙三醇和Co(Ⅱ)进行实验研究。详细分析了其抑制氨逃逸机制,并通过IR、XRD等对物种进行分析。同时探究其对再生氨法碳捕集过程CO2脱除效率和解吸效果的影响。实验结果表明,丙三醇和Co(Ⅱ)对氨逃逸均有较好的抑制效果,平均抑氨效率在40%以上。二者的引入对吸收过程均无显著影响,且Co(Ⅱ)能使CO2解吸比例提高。
