摘要(Abstract):

随着现代煤化工的快速发展,其生产过程中排放的大量挥发性有机物(VOCs)将对当前空气质量产生多重环境效应。但是目前对现代煤化工项目生产过程中排放的VOCs的认识还无法满足大气污染治理的管理和决策需求。针对这一问题,论文采用污染源源强核算的方法,对比分析了现代煤化工和石化行业VOCs排放特征;在文献分析和实地调研基础上,基于石化行业VOCs污染治理的成熟经验,分析了现代煤化工企业VOCs防控薄弱环节,探索跨越污染防控主要障碍方法。研究发现,废水集输、储存、处理处置过程逸散是现代煤化工企业VOCs最大排放源,与石化企业VOCs排放特征存在明显差异;排放底数不清是煤化工行业VOCs污染控制管理的主要障碍,建立在线监测技术规范指导现代煤化工行业固定污染源的VOCs排放在线监测,有助于提升整个行业VOCs污染防控水平。通过分析国内外固定污染源VOCs监测技术方法,基于我国固定污染源污染物排放在线监测的技术规范,研究建立了我国现代煤化工行业固定污染源VOCs排放在线监测技术系统,并阐述了该系统的组成和结构、技术性能、监测站房、安装、技术指标调试检测、技术验收、日常运行管理、日常运行质量保证以及数据审核和处理等方面的要求。该系统标准的研究为我国煤化工行业VOCs排放监测系统的建立提供了参考。
With the rapid growth of modern coal chemical industry,a large number of volatile organic compounds(VOCs) emitted from its production processes will pose multiple environmental effects on the currentair quality. At present,the knowledge about the emission of VOCs from the production process of modern coal chemical projects is not enough to meet the management and decision-making needs of VOCs pollution control. To overcome this difficulty,the method of pollution source intensity calculation was adopted to compare and analyze the difference of the VOCs emission characteristics between modern coal chemical industry and petrochemical industry. Also the literature analysis and field research was conducted to analyze the weak links of VOCs prevention and control in modern coal chemical enterprises and explore the methods to overcome the main obstacles of pollution prevention and control based on the mature experience of VOCs pollution control obtained in petrochemical industry. It is found that the VOCs emission during gathering,transportation and treatment of waste water is the biggest emission source in modern coal chemical enterprise,which is obviously different with the VOCs emission characteristics of petrochemical enterprise. Unclear emission base is the main obstacle of VOCs pollution control in modern coal chemical industry. It is helpful to improve the VOCs pollution control level of modern coal chemical industry by establishing performance specification of VOCs continuous emission monitoring system to guide the on-line monitoring for VOCs emission from stationary pollution source. Based on the VOCs monitoring technologies at home and abroad,and the technical specifications of China's on-line monitoring of fixed pollution source emissions,an on-line monitoring technology system of fixed pollution source VOCs emissions in China's modern coal chemical industry was studied and established,and the requirements for system component and structure,technical performance,monitoring station,installation,debugging and test for technical indicator,acceptance,daily operation management,quality assurance,data auditing and treatment and other aspects of the system were elaborated. The study of the system standard provided a reference for the establishment of VOCs emission monitoring system in China's coal chemical industry.
