【摘要】：温室气体排放导致的气候变暖现象已得到全世界各国的广泛关注,被公认为全球重要的环境问题。自2005年2月16日《京都议定书》正式生效以来,我国已开展了一系列温室气体排放源、排放量化以及减排潜力等方面的研究工作,主要集中在电力、钢铁、化工、水泥等重点行业,关于炼焦行业温室气体排放相关研究较少。作为钢铁工业的上游产业,炼焦生产属于重要的能源加工产业,一直以来都是山西省主要支柱产业之一,也是最重要的温室气体排放源之一,炼焦行业面临着温室气体减排的巨大压力。因此,研究筛选适合炼焦行业量化计划的温室气体排放核算方法,建立适合炼焦生产实际的温室气体排放影响因素指标体系并对其进行评价分析,对于焦化行业温室气体减排有重要的理论和现实意义。据此本文进行了如下研究:首先,基于山西省焦化行业生产实际,分析了不同炼焦工艺的碳物质流,在此基础上对焦化企业生产过程温室气体排放源进行分析识别。对国内外现行各类温室气体排放核算方法进行筛选和整合,针对12家样本企业进行实证研究,并对炼焦生产温室气体排放估算因子进行了优化。其次,开展了企业实地调研和行业专家咨询,分析筛选出炼焦行业温室气体排放影响因素,参考炼焦行业清洁生产标准,建立了温室气体排放影响因素指标体系;该体系根据排放类型分为四大类影响因素和三个指标层次,基本能全面表征企业排放水平。最后,运用层次分析法、主成分分析法和灰色关联分析法相结合对指标体系中各因素进行排序评价,并根据评价结果针对性提出的减少碳排放的建议。评价结果表明:炼焦企业温室气体排放以化石燃料燃烧排放为主,所占比重达66%;影响因素中单位燃气含碳量、结焦时间、电力消耗和焦炉密封性等较为重要,影响权重分别是20%、14%、13%和6%;因此炼焦企业应结合碳排放主要影响因素,进行碳减排途径选择和方案确定。本文研究结论可为炼焦行业开展低碳减排相关研究和制定低碳发展技术政策提供参考。
[Abstract]:Global warming caused by greenhouse gas emissions has been widely concerned by countries all over the world, and has been recognized as an important global environmental problem. Since February 16th 2005, the Kyoto Protocol has come into effect. China has carried out a series of greenhouse gas emission sources, emissions and emission reduction potential and other aspects of research work, mainly focused on electricity, steel, chemical, cement and other key industries. As the upstream industry of iron and steel industry, coking production is an important energy processing industry, has been one of the main pillar industries in Shanxi Province. It is also one of the most important sources of greenhouse gas emissions, coking industry is facing great pressure of greenhouse gas emission reduction. An index system of greenhouse gas emission factors suitable for coking production was established and evaluated. For the coking industry greenhouse gas emission reduction has important theoretical and practical significance. According to this paper the following research is carried out: firstly based on the actual production of Shanxi coking industry the carbon material flow of different coking processes is analyzed. On this basis, the greenhouse gas emission sources in the production process of coking enterprises are analyzed and identified. The current accounting methods of greenhouse gas emissions at home and abroad are screened and integrated, and the empirical research is carried out for 12 sample enterprises. And the coking production greenhouse gas emission estimation factors were optimized. Secondly, the enterprise field investigation and industry expert consultation were carried out to analyze and screen out the factors affecting the coking industry greenhouse gas emissions. With reference to the standard of cleaner production in coking industry, the index system of influencing factors of greenhouse gas emission is established. According to the emission types, the system can be divided into four categories of factors and three index levels, basically can fully characterize the level of enterprise emissions. Finally, the use of analytic hierarchy process. Principal component Analysis (PCA) and Grey correlation Analysis (GRA) were combined to evaluate all the factors in the index system. According to the evaluation results, some suggestions for reducing carbon emissions are put forward. The results show that the main greenhouse gas emissions of coking enterprises are fossil fuel combustion, accounting for 66%; The carbon content of unit gas, coking time, power consumption and seal of coke oven are more important, the influence weight is 2014% and 6% respectively. Therefore, coking enterprises should combine the main factors of carbon emissions. The conclusion of this paper can provide a reference for the development of low-carbon emission reduction related research and the formulation of low-carbon development technology policy in coking industry.
