【摘要】：随着能源消费不断增加,石油资源的日益枯竭,21世纪世界各国正面临着严峻的能源战略问题,而我国是一个“富煤少油缺气”的国家,大力发展煤化工产业,对于补充国内油气资源不足、满足化工产品需求、降低石油对外依存度、保障能源安全等具有重要的能源安全战略意义。煤化工作为一个新兴产业,具有能耗大、水耗大、三废产生量大等特点,其发展过程中对煤炭资源、水资源、生态、环境、技术、资金和社会配套条件要求较高。然而,在其发展初期,一些地方不顾资源、生态、环境等方面的承载力,出现盲目规划、竞相上煤化工项目的势头,从而导致了资源利用不合理、环境保护重视不够、各地开建项目缺乏管理等一系列问题的出现,不利于煤化工产业的长久、稳定和可持续的发展。本文以我国西部地区—甘肃平凉地区的煤化工产业发展现状为研究对象,首先对国内外煤化工产业发展现状及发展过程中存在的问题进行了详细的综述,.并列出了我国主要、典型的煤化工政策,该部分奠定了本文的研究基础；其次,本论文对甘肃平凉地区煤化工产业发展现状、产业链结构、发展趋势及区域环境资源进行了详细分析,根据分析结果,找出了该地区煤化工产业发展中存在的问题和相应的环境资源制约因素；最后,根据存在的问题和相应的制约因素,本文提出了煤化工产业发展对策体系,具体分为五个部分,即源头预防对策、过程控制对策、污染治理对策、循环化改造阶段对策和环境管理对策,并将煤化工产业循环化改造作为解决当地现有煤化产业工发展过程中存在的问题和相应环境制约因素最核心的对策。在此基础上,本文创建了一套煤化工产业循环化改造水平的评价指标体系,通过层次分析法确定了指标体系中各指标的权重,并结合线性加权的评价方法,对平凉地区现有煤化工产业发展水平进行评价,给出了优化后的煤化工循环经济产业链,对产业链循环化改造的效益进行了分析,以期为我国西部地区煤化工产业的发展提供参考性建议。
[Abstract]:With the increase of energy consumption and the depletion of petroleum resources, every country in the world is facing severe energy strategic problems in the 21st century. However, China is a country with "rich coal, less oil and less gas", and vigorously develops the coal chemical industry. It is of great strategic significance to supplement the shortage of domestic oil and gas resources, meet the demand of chemical products, reduce the degree of dependence of oil on the outside, and ensure energy security. Coal chemical industry, as a new industry, has the characteristics of large energy consumption, large water consumption and large amount of waste production. In the process of its development, coal resources, water resources, ecology, environment, technology, capital and social supporting conditions are required. However, in the early stage of its development, some places, regardless of the carrying capacity of resources, ecology, environment and so on, appeared blind planning, competing with each other in the momentum of coal chemical projects, which led to unreasonable utilization of resources and insufficient attention to environmental protection. A series of problems, such as lack of management, are not conducive to the long-term, stable and sustainable development of coal chemical industry. In this paper, the coal chemical industry in the western part of China-Pingliang area of Gansu Province is taken as the research object. Firstly, the status quo and problems existing in the development process of the coal chemical industry at home and abroad are summarized in detail. And listed the main, typical coal chemical policy, this part has laid the foundation of this paper. Secondly, this paper on the status quo of coal chemical industry development in Pingliang, Gansu Province, industrial chain structure, The development trend and regional environmental resources are analyzed in detail. According to the results of the analysis, the problems existing in the development of coal chemical industry in this area and the corresponding environmental resource constraints are found out, and finally, according to the existing problems and the corresponding restrictive factors, This paper puts forward the development countermeasure system of coal chemical industry, which is divided into five parts, namely, source prevention countermeasure, process control countermeasure, pollution control countermeasure, recycle transformation stage countermeasure and environment management countermeasure. The circular transformation of coal chemical industry is regarded as the key countermeasure to solve the problems existing in the development of local coal chemical industry and the corresponding environmental constraints. On this basis, this paper has established a set of evaluation index system of coal chemical industry circular transformation level, determined the weight of each index in the index system by analytic hierarchy process, and combined with the evaluation method of linear weighting. This paper evaluates the development level of coal chemical industry in Pingliang area, presents the optimized circular economic industrial chain of coal chemical industry, and analyzes the benefit of recycling transformation of industrial chain. In order to provide reference suggestions for the development of coal chemical industry in western China.
