摘　　要：耦合多种碳排放源识别方法,分析石油焦煅烧过程中的碳排放源。通过数学模型的搭建,以某石油焦煅烧企业为例,计算并分析整个生产过程中的碳排放量。研究结果表明:整个煅烧过程中的总碳排放为0.509904 t CO_(2)/t_(煅烧焦),净碳排放量为0.141942 t CO_(2)/t_(煅烧焦),挥发分燃烧碳排放在总碳排放中占比最大,为68.51%。最后指出,降低生产过程碳排放和加强余热回收利用,是今后煅烧企业节能减碳的发展方向。Coupled with a variety of carbon emission source identification methods,the carbon emission source of petroleum coke calcination process is analyzed.Through the establishment of a mathematical model,taking a petroleum coke calcination enterprise as an example,the carbon emission in the whole production process is calculated and analyzed.The results show that the total carbon emission of the whole calcination process is 0.509904 t CO_(2)/t_(CPC),the net carbon emission is 0.141942 t CO_(2)/t_(CPC),and the carbon emission of volatile combustion accounts for the largest proportion of the total carbon emission,which is 68.51%.Finally,it is pointed out that it is the development direction of energy saving and carbon reduction in calcination enterprises to reduce carbon emission and strengthen the waste heat recovery in the future.
