Hazardous chemical leakage accidents and emergency evacuation response ...
2021年3月1日 · Analyzing emergency evacuations caused by the hazardous chemical leaks, it can be seen that HCLAs in the pipeline transportation are most likely to cause regional evacuations, most of the evacuations take place in rural areas, and fuel gas and ammonia leaks are the main hazardous chemicals that lead to evacuations.
Leak detection and pressure testing in chemical production …
Our SeeperTrace™ leak detection service quickly, accurately and cost-effectively locates leaks in buried long-distance pipelines that carry liquids, gases or multi-phase products. It involves adding a tracer to either nitrogen gas or water. A leak as small as 2.5 gallons per day can be detected without service interruption or excavation.
Leak detection systems (LDS) are needed because pipeline spills occur more frequently as infrastructure ages and more hazardous products are transported. Leak detection systems cannot prevent leaks, but they can certainly help minimize the consequence of leak.
Review and analysis of pipeline leak detection methods
2022年12月1日 · Wang et al. (2022) presented a novel pipeline leak detection and localization method integrating compressed sensing theory with FBG pipe-fixture sensor array to accurately determine the leakage point without solving for the arrival time difference, increasing the localization accuracy and stability, without increasing the number of sensors.
