摘要(Abstract):

我国煤炭资源丰富,煤化工技术是重要的能源战略需求之一。我国现已形成以煤焦化、合成氨等为主的传统煤化工产业和以煤气化、煤液化为核心的煤制天然气、煤制油、煤制烯烃、煤制芳烃等现代煤化工产业。完善的煤化工标准化体系有利于行业进一步发展,因此本文全面综述了煤化工标准化工作的研究情况,统计了我国煤化工领域现行和即将实施的国家及行业标准,重点从煤气化、煤间接液化、煤直接液化、煤制天然气、煤制甲醇、煤制烯烃、煤制芳烃、煤制乙二醇、煤制二甲醚等9个主要领域介绍了现代煤化工标准的制定情况并对新标准的制定提出建议。我国煤化工标准体系由基础标准、管理标准、产品标准和检验检测标准4大类构成。截至2019年1月,据不完全统计,我国煤化工领域已颁布实施国标、行标229项,其中,基础标准5项;传统煤化工领域标准154项,2019年1月后实施标准3项;现代煤化工领域标准70项,2019年1月后实施标准12项。传统煤化工标准类别覆盖较为全面,但应加快标准的修订更新工作以加速淘汰落后技术,助力化解产能过剩;现代煤化工标准工作虽然近年来有了长足的进展,但主要问题在于已颁布实施的标准多偏重检验检测方法类,而煤基产品类标准偏少且仅覆盖产业链少数主要产品,另外针对煤化工行业的环保、操作规程、技术装备、工程建设等标准空白较多。现阶段,标准化工作的任务仍以新标准的研发为主,应以煤化工产业的总体发展及相关国家政策为导向,加快单位产品能耗限额、取水定额、三废排放及治理、清洁生产等节能环保类标准以及装备技术类标准的制修订工作,通过标准的建立规范和引导产业绿色、健康发展。另一方面,在推进煤炭清洁高效利用技术相关标准建立的同时,应注重加强煤化工产业与发电、油气化工、钢铁、建材等其他行业的联系并建立相关的技术标准。未来在以政府为主导、企业团体协调配合的新型标准体系的支撑及"一带一路"战略的引领下,先进、完善的标准化体系将更好地助力煤化工产业的发展。
There is abundant coal resource in China.Modern coal chemical technology is vital for energy security in our country.The traditional coal chemical industry is dominated by coking and synthetic ammonia. The modern coal chemical industry takes coal gasification and coal liquefaction as the core,including coal to natural gas,coal to oil,coal to olefins,and coal to aromatics and so on. The perfect standardization system is conducive to the further development of coal chemical industry.In this paper,the research on the standardization of coal chemical industry was introduced and the existing and upcoming national and branch standards were reviewed.The current standardization of some important fields in modern coal chemical industry was introduced in 9 main fields including coal gasification,coal indirect liquefaction,coal direct liquefaction,coal to natural gas,coal to methanol,coal to olefin,coal to aromatics,coal to glycol,and coal to dimethyl ether. Moreover,in this paper,some suggestions were put forward for the development of some new standards. The standard system of coal chemical industry consists of four categories:basic standards,management standards,product standards and testing standards. As of January 2019,according to incomplete statistics,the 229 national and branch standards including 5 basic standards have been issued in coal chemical industry. In the traditional coal chemical industry,154 standards have been issued and 3 standards will be implemented after January 2019. In the modern coal chemical industry,70 standards have been issued and 12 standards will be implemented after January 2019. It is found that in the traditional coal chemical industry,standards cover a wide range of areas. However,the revision and update of the standards should be accelerated to speed up the elimination of backward technologies and help resolve overcapacity. Although the standard work of modern coal chemical industry has made great progress in recent years,the main problem lies in that the issued and implemented standards mainly focus on inspection and detection methods,while the standards of coal-based products are less and only cover a few major products in the industrial chain,and there are many blank standards for environmental protection,operating procedures,technical equipment,engineering construction,etc. in the coal chemical industry. At the present stage,the task of standardization is still dominated by the research and development of new standards,which should be guided by the overall development of coal chemical industry and relevant national policies. Accelerate the formulation and revision of energy conservation and environmental protection standards such as energy consumption quota,water intake quota,three wastes discharge and treatment,clean production and equipment technology standards,and guide the green and healthy development of the industry through the establishment of standards.On the other hand,while the establishment of relevant technical standards for clean and efficient utilization of coal is being promoted,attention should be focused on strengthening the relationship between coal chemical industry and power generation,oil and gas chemical industry,steel,building materials and other industries and establishing relevant technical standards.In the future,under the support of the new standard system led by the government and coordinated by enterprises and groups and the guidance of the "One Belt and One Road" strategy,the advanced and perfect standardization system will better facilitate the development of the coal chemical industry.
