A novel photoacoustic spectrometer (PA) has been developed for in-situ detection of SF/sub 6/ leaks in low concentrations. The developed system is equipped with a sound alarm system and has been tested in the laboratory for very minute SF/sub 6/…
Treatment with pour point depressant (PPD) can significantly improve the cold flowability of waxy crude oil, enabling the safe and efficient transportation of waxy crude oils through pipelines. It has been observed that the electrical properties of…
Reliable corrosion monitoring of natural gas transmission lines is a major tool providing a foundation for safe management of natural gas infrastructures. Through the development of membrane-based electrochemical sensors which are able to function in…
This article provides a method to design a viscosity reducing agent, which builds a crude oil model through molecular simulation and calculates the type of monomer suitable for the viscosity reduction of the crude oil. Viscosity reducing agent was…
Hyperspectral imaging technology is a rapid and nondestructive technique, which has the characteristic of combining the image and spectra, each band will represent an image, each pixel displays a spectra. Hyperpectral image can not only obtain…

Hydrocarbon microseepage theory establishes a cause-and-effect relation between oil and gas reservoirs and special surface anomalies, mainly including surface hydrocarbons and related mineral alterations. Thus, diagnostic spectral features of…
In order to reduce the weight of transportation, power transformers are often filled with nitrogen gas at transformer substation or factory, in which their insulating performance will degraded because of moisture intrusion, ambient temperature…

In this paper, an experimental study was conducted using terahertz (THz) spectroscopy to assess the electromagnetic properties in the THz range of various materials that can be found in oil and gas fields. This includes the absorbance, transmittance,…
Crude oil pollution is a global environmental concern since it persists in the environment longer than most conventional carbon sources. In December 2014, the hyper-arid Evrona Nature Reserve, Israel, experienced large-scale contamination when crude…
