A Novel Liquid and Gas Pipeline Leak Detection System
Methane is one of the most serious greenhouse gases contributing to irreversible climate change. The contribution of methane emissions from leaking pipelines and the expected increased throughput through the pipelines prompted the natural gas industry to set a goal of reducing emissions by 50% by 2010. The integrity of the pipelines is critical to the safety of the gas transportation infrastruc...
متن کاملDetection of a simulated gas leak in a wind tunnel
This paper brings together considerations of gas leak behaviour and leak detector design and use, with a view to improving the detection of low-pressure natural gas leaks. An atmospheric boundary layer wind tunnel has been used to study ground–based releases of methane at full scale over distances of up to 3 m, under controlled conditions. These scales are relevant to the detection of natural g...
متن کاملTechnology Status Report on Natural Gas Leak Detection in Pipelines
However, any opinions, findings, conclusions, or recommendations expressed herein are those of the author and do not necessarily reflect the views of the DOE". Natural gas consumption in the US is expected to increase 50% within the next 20 years (Anderson and Driscoll, 2000). At the same time, the gas delivery infrastructure is rapidly aging. The Department of Energy has stated that ensuring n...
متن کاملGas Leak Detection by Dilution of Atmospheric Oxygen
Gas leak detection is an important issue in infrastructure monitoring and industrial production. In this context, infrared (IR) absorption spectroscopy is a major measurement method. It can be applied in an extractive or remote detection scheme. Tunable laser spectroscopy (TLS) instruments are able to detect CH₄ leaks with column densities below 10 ppm·m from a distance of 30 m in less than a s...
متن کاملWireless Sensor Node for Gas Pipeline Leak Detection and Location
Many different wireless sensor nodes for gas pipeline leak detection and location has been proposed but still there are challenges particularly on environmental issues and signal accuracy. This paper discusses theories and environmental constraints for wireless sensor nodes, a case study of Dar es Salaam Tanzania and finally presents a design and simulation results of the proposed wireless sens...
