【摘要】：近年来，随着社会经济的迅速发展，河南省面临的环境和能源压力日益加重。化工行业因其复杂的产品结构和巨大的产业规模而成为河南省难以治理的高耗能和高污染行业。利用技术改造是化工行业降低能耗和污染的核心措施，因此大力推广经济可行的节能技术是河南省在化工行业实现节能减排的重要途径。但目前我国尚未建立完善的节能技术评价体系，如何从众多的节能技术中筛选出经济可行的节能技术成为当前政府和企业面临的难题。在此背景下，本文采用节能成本评价法对河南省化工行业的节能技术进行评价，并对不同技术的节能潜力进行分析研究。首先对河南省化工行业现状进行调研，分别从产能、产量和技术等方面对目前化工行业的发展现状进行概括，并在此基础上选择合成氨、烧碱、纯碱和电石四个行业作为重点研究对象。然后采用节能成本评价法和节能供给曲线对四个高耗能行业的节能技术进行评估，并结合各行业新增产能以及淘汰产能的节能情况来分析未来目标年河南省化工行业的节能潜力。最后通过情景分析和敏感性分析来评估能源价格、政府补贴和折现率等因素对节能技术推广以及化工行业节能潜力的影响。研究结果表明：第一，通过利用有效节能技术推广、新增产能能效控制以及淘汰落后产能这三大节能路线途径，从2010到2020年河南省化工行业可实现节能量168.54万tce。其中通过节能技术改造可实现节能量128.26万tce，对节能潜力贡献率最大，占总节能量比重的73%。第二，通过节能技术评价共计筛选出33项经济可行的化工节能技术，可实现节能潜力111.81万tce，其中合成氨行业所占份额最大为71.24万tce，，未来应重点加强合成氨行业的相关节能技术投资建设。第三，通过情景分析可知，政策补贴和能源价格对河南省化工行业节能技术推广影响显著。未来随着能源价格上涨和政策补贴加强，使更多节能技术变得可行有效，使节能潜力增加14%。最后提出建议，要求进一步完善节能技术评价体系和加大重点节能技术推广力度。
[Abstract]:In recent years, with the rapid development of social economy. The environmental and energy pressure in Henan Province is increasing day by day. Because of its complex product structure and huge industrial scale, the chemical industry has become a high energy consumption and high pollution industry in Henan Province. The utilization of technology transformation is a chemical industry. Core measures to reduce energy consumption and pollution in the industry. Therefore, popularizing economically feasible energy saving technology is an important way to realize energy saving and emission reduction in chemical industry in Henan Province. However, at present, our country has not established a perfect energy saving technology evaluation system. How to select the economical and feasible energy saving technology from many energy saving technologies has become a difficult problem for the government and enterprises. Under this background, this paper uses the energy saving cost evaluation method to evaluate the energy saving technology of Henan chemical industry. The energy saving potential of different technologies is analyzed and studied. Firstly, the status quo of chemical industry in Henan Province is investigated, and the development status of chemical industry is summarized from the aspects of production capacity, output and technology respectively. On the basis of this, four industries of synthetic ammonia, caustic soda, soda and calcium carbide were selected as the key research objects, and then the energy-saving technology of the four high-energy consuming industries was evaluated by the energy-saving cost evaluation method and the energy-saving supply curve. The energy saving potential of chemical industry in Henan Province in the next target year is analyzed by combining the new production capacity and the energy saving situation of eliminating capacity. Finally, the energy price is evaluated by scenario analysis and sensitivity analysis. The influence of government subsidy and discount rate on energy saving technology popularization and energy saving potential of chemical industry. The results show that: first, through the use of effective energy-saving technology promotion, new capacity energy efficiency control and elimination of backward production capacity these three major energy-saving routes. From 2010 to 2020, Henan chemical industry can achieve energy saving of one million six hundred and eighty-five thousand and four hundred TceS, among which energy saving one million two hundred and eighty-two thousand and six hundred tce can be realized through energy saving technology transformation. The contribution rate to energy saving potential is the largest, which accounts for 73% of total energy saving. Second, 33 economically feasible chemical energy saving technologies are selected through energy saving technology evaluation. The potential of energy saving can be realized by one million one hundred and eighteen thousand and one hundred Tces, of which the largest share of synthetic ammonia industry is 712,400 Tces.In the future, we should focus on strengthening the investment and construction of related energy-saving technologies in the synthetic ammonia industry. According to the scenario analysis, policy subsidies and energy prices have a significant impact on the promotion of energy-saving technology in Henan chemical industry. In the future, with the increase of energy prices and the strengthening of policy subsidies, more energy-saving technologies become feasible and effective. Finally, suggestions are put forward to further improve the evaluation system of energy-saving technology and strengthen the popularization of key energy-saving technology.
