【摘要】 根据《中国钢铁生产企业温室气体排放核算方法与报告指南（试行）》（简称《钢铁核算指南》）计算方法和碳平衡法计算A钢铁公司（包含炼焦工序）和B钢铁公司（不包含炼焦工序）CO₂排放量.计算结果表明,按《钢铁核算指南》方法计算的CO₂排放量明显偏小.为使计算结果更加准确,提出两种钢铁企业CO₂排放量修正方法,方法 1是在《钢铁核算指南》方法基础上,增加计算自产生铁中的碳产生的CO₂排放;方法 2是在不考虑自产生铁碳排放的情况下,提高铁前工序消耗的煤和焦炭的碳氧化率到99%,其他原煤的碳氧化率仍按《钢铁核算指南》取值.以上两种修正方法计算结果与碳平衡法计算出的排放量相近,更加接近企业实际排放量.更多还原

【Abstract】 According to the calculation method of"Guidelines for Accounting and Reporting Greenhouse Gas Emissions of Chinese Iron and Steel Enterprises（Trial）"（hereinafter referred to as Guidelines for Iron and Steel Accounting）and carbon balance method,the CO₂ emissions of A Steel Company（including coking process）and B Steel Company（excluding coking process）were calculated. The calculation results show that the CO₂ emissions calculated by the "Guidelines for Iron and Steel Accounting" method are significantly smaller than those calculated by the carbon balance method. In order to make the calculation results more accurate,two correction methods of carbon dioxide emission for iron and steel enterprises were proposed in this paper. The first method is to calculate the carbon dioxide emission from selfproduced iron in addition based on the method of" Guidelines for Iron and Steel Accounting". The second method is to increase the carbon oxidation rate of coal and coke consumed in the pre-iron process to 99% without considering the carbon emission of self-produced iron. The carbon oxidation rate of other raw coal is still determined according to the Guidelines for Iron and Steel accounting. The calculated results of the above two correction methods are similar to those of the carbon balance method,which is closer to the actual emissions of enterprises.更多还原
