摘　　要：由温室气体排放产生的环境问题已经成为人类面临的重大挑战,中国碳排放量核算工作仍处于起步阶段,需要不断完善和提高。以某炼化企业为统计数据源,通过摸查炼化行业通用装置的CO_(2)排放情况,开展标准科学的碳排放核算工作,以此制定有效的减排措施。结果表明,核算过程中热电运行部燃煤烟气排放、己二酸装置N_(2)O尾气分解率、火炬气流量和组成等取值存在较大不确定性,导致核算值与理论值偏差较大。研究认为:通过与生产实际对比,可寻找提高核算数据准确性的可行方法,指导日后采取相应的改进措施;通过核算工作可以掌握企业碳排放情况,切实推进可行的低碳减排优化措施,为促进企业绿色健康长远发展奠定基础。One of the greatest challenges that humanity is currently dealing with is the destruction of the environment brought on by greenhouse gas emissions.China’s carbon emission accounting is still in its infancy and needs ongoing improvement.This paper takes a refining enterprise as a source of statistical data,and carries out standard scientific carbon emission accounting by mapping the CO2 emissions of general-purpose devices in the refining industry,so as to formulate effective measures to reduce emissions.The findings indicate that there are significant uncertainties in the values of coal-fired flue gas emissions from the thermal power operation sector,the N2O tail gas decomposition rate of the adipic acid unit,and the flare gas flow and composition during the accounting process.As a result,there are significant differences between the accounting values and the theoretical values.The investigation came to the conclusion that practical methods to increase the accuracy of accounting data may be found by comparing with actual production,which will help direct the adoption of appropriate improvement measures in the future.And through accounting work,we can understand the carbon emission position of the refineries,effectively support viable strategies to optimize low-carbon emission reduction,and lay the foundation for promoting their long-term green development.
