中文摘要:

      本文分析了适用于焦化行业通用CO₂排放核算方法,在此基础上结合我国焦化行业工艺和原料的特征,采用排放因子法和物料衡算法等两种方法对10家典型焦化企业CO₂排放进行核算。结果表明:物料衡算法能很好地反映不同类型焦化企业的排放特征;排放因子法对我国独立焦化企业存在碳排放量系统性高估的可能。为此,建议我国焦化企业可借鉴德国焦化企业的碳核算经验,采用碳平衡法对不同类型的焦化企业(单元)的碳排放量进行核算,并完善相关的统计和监测技术。

英文摘要:

      Based on the analysis of carbon emissionaccounting methodsincoking industry, combining with its processes and material characteristics, the emissions of 10 typical coking enterprises were calculated using material balance method and discharge coefficient method, respectively. The results indicated that the material balance method could clearly reflect the carbon emission characteristics of coking enterprises with different production processes, on the other side, the discharge coefficient method had a great potential for overestimating the carbon emission of independent coking enterprises and even the entire coking industry. Therefore, it was recommended to use the German experience as a reference which was using carbon balance method to account the carbon emission of coking enterprises, meanwhile the basic statistical and monitoring system of coking enterprises need to be improved.
