Pipelines are one of the most common systems for storing and transporting petroleum products, both liquid and gaseous. Despite their durable structures, leakages can occur for many reasons, causing environmental disasters, energy waste, and, in some…
In this paper, we have proposed a Liquefied Petroleum Gas (LPG) monitoring and leakage detection system. With the large demand and use of LPG, this system would be helpful to monitor the usage of LPG on a regular basis and to alert about any hazards…
Field-pipeline operations are more easily affected by complex environment in comparison of common long-distance pipeline. Its failures such as leakage demand to be dealt with more urgently and efficiently. This paper proposes a leakage detection…
Many methods have been proposed for leak detection in pipelines. The method based on the acoustic signals created by the leakage is a non-destructive method and has presented reliable results. However, applying such a method in noisy environments is…
Static pressure method and dynamic pressure method were commonly used in pipeline leak detection. Advantages and disadvantages of the two methods were analyzed and a dynamic pressure sensor was designed for long-range oil and gas transmission…
Leakage is the most common cause of natural gas pipeline accidents. This work was devoted to natural gas pipeline leakage detection, which is based on detecting negative pressure wave signals caused by leakage. The FBG strain sensor, which is based…
