摘要
为探明化产回收型独立焦化企业在当前生产技术水平下吨焦CO_(2)排放量及其在不同生产负荷下的CO_(2)排放情况,对山西省3家企业2020年实际生产状况和生产数据进行了调查,在分析企业CO_(2)排放源的基础上,参考《中国独立焦化企业温室气体排放核算方法与报告指南(试行)》中的核算边界与方法进行计算并分析。结果表明,在当前生产技术水平下,独立焦化企业的吨焦CO_(2)排放量为240~320 kg/t;焦炉大型化在不同程度上可以减少CO_(2)排放,但限产、停炉保温等操作将会导致焦化企业吨焦CO_(2)排放量大幅上升。
In order to find out the CO_(2)emissions per ton of coke in independent coking enterprises with different carbonization chamber heights under the current production technology level and their CO_(2)emissions under different production loads,the actual production situation and production data of three typical independent coking enterprises with chemical production recovery in 2020 are investigated.On the basis of analyzing the CO_(2)emission sources of these three enterprises,the calculation and analysis are carried out with reference to the accounting boundary and methods in the‘China Independent Coking Enterprises GHG Emission Accounting Methodology and Reporting Guide(for trial implementation)’.The results show that under the current production technology level,the CO_(2)emissions in independent coking enterprises are about 240-320 kgCO_(2)per ton of dry whole coke.The large size of coke ovens can reduce CO_(2)emissions to different degrees.However,the practices such as production limitation and furnace shutdown will lead to a significant increase in CO_(2)emissions per ton of coke.
