摘要
美国环保署(EPA)在世界上最早推行泄漏检测与修复技术(LDAR),控制石化企业设备泄漏挥发性有机物(VOCs)排放,发展至今经历了初级(1983-1999年)和高级(2000-2020年前后)阶段,目前处于技术革新初期,其发展历程和经验对中国LDAR政策、法规、标准制定和技术发展有借鉴意义.本文简要介绍了美国LDAR的创建、发展、技术进步及质量升级的历程,评述了 LDAR等效减排的机制及相关进展,以及传感器在线检测、红外气体成像(OGI)检测、低排放密封等LDAR革新技术进展,展望了 LDAR未来发展趋势.文章提出,总体上,美国的传感器在线检测、OGI检测和低排放密封等LDAR新技术研发应用世界领先,传感器网络智能在线检测技术可能是LDAR技术革新或下一代LDAR研发的主方向,设备低排放密封技术是LDAR的重要辅助手段,OGI是重要的LDAR非常规检测技术.
Abstract
The U.S.Environmental Protection Agency(EPA)was the first in the world to introduce leak detection and repair technology(LDAR)to control fugitive volatile organic compounds(VOCs)emissions from equipment leaks in petroleum refining and petrochemical industry.They have experienced the primary(1983-1999)and enhanced(around 2000-2020)stages,and is currently in the early stage of technological innovation.Their development history and experience are significant reference for policies,regulations,standards and techniques related to LDAR in China.This paper outlines the foundation and development of LDAR,technological progress and quality improvement in the United States,as well as the equivalent emission reduction policies and alternative means of emission control for LDAR.Additionally,the progress of technical innovations and the application such as optical gas imaging(OGI)detection,low-emission techniques,sensor-based automated and continuous detection and other high temporal and spatial resolution monitoring technologies is discussed and compared to LDAR.The future development of LDAR technology upgrades and innovations is explored.In general,the United States lead the world in the development and application of innovative LDAR technologies such as sensor-based leak detection,OGI detection and low-emission sealing techniques.Intelligent leak detection sensor network will probably be the dominant direction of LDAR technology innovation or next-generation LDAR research and development.Low-emission sealing technology will probably be an important auxiliary method to LDAR,while OGI will be an important alternative and supplementary LDAR detection technology.
