| 摘 要： | 以高能耗为主要特征的工业部门是大气污染物和温室气体的重要排放源。为推动协同管控,文中结合生态环境部在重庆市组织开展的试点工作,对工业企业NOx污染治理协同控制温室气体的效应进行了量化分析。结果表明,以末端治理为手段的NOx治理措施协同控制温室气体的效果为负,即工业企业去除1 t NOx会直接或间接增加CO2排放1.811 t,采用SNCR技术且选择氨水等非尿素类脱硝剂有助于减少工艺过程和电力间接CO2排放。2017年工业企业NOx减排导致CO2排放增加52.57万t,占重庆市能源活动CO2排放总量的0.3%。电力碳排放因子降低1%和降低5%情景下,NOx减排的总协同度将分别提高0.9%和4.3%,尤以水泥制造业的协同效果改善最明显。减少尿素使用和提高电力低碳化程度有助于降低工业领域NOx减排对CO2排放的负协同效果。

| Abstract: | Industrial sectors characterized by high energy consumption are considered as important sources of atmospheric pollutants and greenhouse gases (GHGs). In order to facilitate the integrated management, this paper combined with the practice in the industrial sectors in Chongqing implemented by Ministry of Ecology and Environment, took NOx as a case pollutant to calculate and analyze the synergy effect between NOx removal and GHGs emissions in the industrial sectors. The results are as follows. The effect of NOx reduction by applying end-of pipe technology is negative to control GHGs, that is, the removal of 1 t NOx in the industrial enterprises will directly or indirectly increase CO2 emissions by 1.811 t. The adoption of SNCR technology and the selection of ammonia and other non-urea denitration agents can help to reduce indirect CO2 emissions from the process and electricity. In 2017, the reduction of NOx in Chongqing’s industrial enterprises increased CO2 emissions by 525.7 kt, accounting for 0.3% of Chongqing’s total CO2 emissions from energy activities. If the power emission factor is reduced by 1% or 5%, the synergetic degree of NOx reduction towards GHGs would be raised by 0.9% or 4.3%, respectively, and the synergistic effect of cement manufacturing is improved the most. It is essential to reduce the negative synergy effect of NOx removal technology by decreasing the use of urea and promoting the development of low carbon power. |
