摘　　要：为推动有机胺法CO_(2)捕集工艺在钢铁行业的应用,在石灰石回转窑炉真实烟气条件下开展了有机胺法CO_(2)捕集侧线试验,考察了有机胺溶液质量分数、烟气流量、溶液喷淋量、吸收温度、油浴温度和再生压力等关键参数对捕集系统CO_(2)捕集性能的影响。结果表明,在最优试验条件(有机胺溶液质量分数为25.0%、烟气流量为20m^(3)/h、溶液喷淋量为70L/h、吸收温度为30℃、油浴温度为115℃以及再生压力为10kPa)下,捕集系统CO_(2)捕集率和解吸酸气量分别为94%和1.22m^(3)/h。在最优试验条件下进行的480h连续试验结果显示,捕集系统CO_(2)捕集率平均值为94%,解吸酸气量平均值为1.22m^(3)/h,CO_(2)捕集系统表现出良好的稳定性,证明有机胺法应用于石灰回转窑烟气CO_(2)捕集技术可行。To promote the application of the organic amine CO_(2) capture process in the steel industry,the sideline test of CO_(2) capture by organic amine method was carried out under lime rotary kiln real flue gas condition.The effects of key parameters such as the mass fraction of organic amine solution,flue gas flow,solution spray amount,absorption temperature,oil bath temperature and regeneration pressure on CO_(2) capture performance of the capture system were investigated.The results show that under the optimal test conditions(the mass fraction of organic amine solution of 25.0%,the flue gas flow of 20 m^(3)/h,the solution spray amount of 70 L/h,the absorption temperature of 30℃,the oil bath temperature of 115℃and the regeneration pressure of 10 kPa),the CO_(2) capture efficiency and the amount of desorption acid gas of the capture system are 94%and 1.22 m^(3)/h,respectively.The results of 480 h continuous test under the optimal test conditions show that the average value of CO_(2) capture efficiency of the capture system is 94%,and the average value of desorption acid gas amount of the capture system is 1.22 m^(3)/h.The CO_(2) capture system shows good stability,which proves that the application of organic amine method to the lime rotary kiln flue gas CO_(2) capture technology is feasible.
