摘要
Abstract
To promote the application of the organic amine CO2 capture process in the steel industry,the sideline test of CO2 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 CO2 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 m3/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 CO2 capture efficiency and the amount of desorption acid gas of the capture system are 94%and 1.22 m3/h,respectively.The results of 480 h continuous test under the optimal test conditions show that the average value of CO2 capture efficiency of the capture system is 94%,and the average value of desorption acid gas amount of the capture system is 1.22 m3/h.The CO2 capture system shows good stability,which proves that the application of organic amine method to the lime rotary kiln flue gas CO2 capture technology is feasible.关键词
