| 中文摘要: |
| 石化装置开停工及检维修过程中的泄压吹扫放空是石化企业VOCs的重要排放源项之一。分析了我国石化企业对停工及检维修的现行操作规范与《石化行业VOCs污染源排查工作指南》中对该源项核算方法参数要求的不符之处，并参照美国炼油厂有毒有害空气污染物国家排放标准的相关规定，提出了监测和操作方面的改进建议。 |
| 英文摘要: |
| Depressurization and purging during petrochemical device startup/shutdown and maintenance process were the main sources of volatile organic compounds (VOCs) emission in petrochemical plant. The inconsistency of emission accounting method between current operation specification for shutdown and maintenance practices in petrochemical plant and “Guidelines for VOCs Pollution Sources in the Petrochemical Industry” was analyzed. Improvement suggestions for monitoring and operation were made referring to U.S.A. National Emission Standards for Hazardous Air Pollutants in Petroleum Refineries. |
