The X-ray transmission imaging technology is often used for nondestructive testing outside the pipe, but for deep buried petroleum pipelines, its equipment cannot meet environmental layout requirements and one side accessible detection devices are…
Leakage is the most important factor for unaccounted losses in any pipe network around the world. However, most state of the art leak detection systems have limited applicability, lack in reliability and/or depend on user experience for data…
Liquefied Petroleum Gas (LPG) is highly inflammable and can burn even at some distance from the source of leakage. One of the preventive actions to avoid the danger associated with gas leakage is to install a gas leakage detector at suitable…
Leakage is the most important factor for unaccounted losses in any pipe network around the world. However, most state-of-the-art leak detection systems have limited applicability, lack in reliability and depend on user experience for data…
Some examples of leaks occurring in pipelines are considered, and an overview of classical leak detection systems and the engineering basis of a novel type of detector system are given. The hydrocarbon sensor system consists of an alarm module and…
The BAM project was conceived to face the problems of the brick construction of the OPERA detector target. An OPERA brick is made of a pile (interleaved lead and nuclear emulsion sheets), kept under a pressure of 3 bar. The brick must be a precise…
A signal reconstruction method for memory-type transient electromagnetic detection systems based on empirical mode decomposition (EMD) was proposed in this study to tackle with the large volume of data saved by the electromagnetic flaw detector in…
Gas chromatography plays a vital role in ensuring the safe running and efficiency of a multitude of chemical production steps mainly in the oil and gas industry, gas processing, refining, Air separation/liquefaction, Power and Alternative Energy,…
Leakages from pipelines are low-probability but high impact events for distributors of crude/refined oil as well as drinking water. Several techniques including geological surveys, fiber optics, acoustics, pressure drop analysis and mass imbalance…
Neutrons can provide information related to the materials with which they interact, that is, to some extent complementary to that provided by X-rays for use in non-intrusive applications. The majority of studies to date have focused on the use of…
