  • Fugitive Gas Emissions In The Petroleum & Natural Gas Industry

    Challenge: Fugitive emissions in the petroleum and natural gas industry can come from a variety of sources and are classified as intentional (venting from tanks, compressor vents and stacks) or unintentional (equipment wear and tear, improper assembly, damage or manufacturing defects).  Most of these fugitive gas leaks are considered insignificant or  too small to ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

  • QuadOa and OGI: how EPA regulations are changing the way we look at gas leaks

    Earlier this year, the Environmental Protection Agency (EPA) published Regulation 40 CFR, Part 60, Sub-part OOOOa, commonly known as Quad Oa, and finally brought optical gas imaging (OGI) firmly into the mainstream. This presents a major shift in the way fugitive emissions are regulated, and the technology that can be used.  Detecting and acting on gas leaks is naturally a major ...

  • Smart LDAR — more cost-effective?

    On December 19, 2008, EPA issued a final rule establishing a voluntary Alternative Work Practice (AWP) to detect leaks of volatile organic compounds (VOC) and hazardous air pollutants (HAP) from process equipment (FR Vol. 73, Number 246), thereby providing the regulated community additional flexibility in complying with leak detection and repair (LDAR) requirements. The AWP allows owners or ...

  • Distributed Thermal-Acoustic Data Integration

    Silixa has developed a technique called Distributed Thermal Acoustics (DTA) to monitor simultaneously the thermal and acoustic profile along a hybrid optical fibre cable in submarine environments. Using its world leading distributed fibre optic technology (ULTIMATM DTS and iDASTM) Silixa deployed an optical fibre cable along the seabed and across the water column in an active gas seepage ...

  • Remote sensing of particulate pollution from space: Have we reached the promised land?

    This paper follows presentation and publication of the Hoff and Christopher 2009 Critical Review and represents an integration of discussants’ views of their paper. The discussants’ comments are organized beginning with a note on the history of satellite sensing, followed with a brief discussion of the strengths and weaknesses of satellite observations relative to air quality management needs. ...

  • A novel spectrometer design for process and handheld infrared spectral measurements

    Introduction Infrared spectroscopy offers many unique advantages for measurements within an industrial environment. Historically, the technique has been used for a broad range of applications from the composition of gas and liquid mixtures to the analysis of trace components for gas purity analysis. In cases where a well-defined method of analysis is involved, such as the measurement of ...

  • Solar fuels: how planes and cars could be powered by the sun

    Solar energy is the world’s most plentiful and ubiquitous energy source, and researchers around the world are pursuing ways to convert sunlight into a useful form. Most people are aware of solar photovoltaics that generate electricity and solar panels that produce hot water. But there is another thrust of solar research: turning sunlight into liquid fuels. Research in solar-derived liquid ...

  • Bubble, bubble … boiling on the double

    Original story at MIT  New analysis of textured surfaces could lead to more efficient, and less dangerous, power plants. The boiling of water is at the heart of many industrial processes, from the operation of electric power plants to chemical processing and desalination. But the ...

  • Peroxygen Mediated Bioremediation of MTBE.

    ABSTRACT: Evidence is mounting, from laboratory and field studies, that oxygen plays a role in the bioremediation of methyl tertiary butyl ether (MTBE). Our experience with a number of commercial applications of peroxygen, in the form of Oxygen Release Compound (ORCâ), correlates the provision of enhanced aerobic conditions with enhanced MTBE biodegradation. Subsequent laboratory and field ...

  • Bird Repellents…Without Them, You`ll Pay Through the Beak

    Why bird repellents, you ask? They sing, bob their heads, flutter their wings and coo. Who can resist the cute little things? In cages, and in small numbers in trees and forests, they"re no bother at all. But nesting in flocks on your property, they soon become pests. Here"s why. Birds Cost Us Millions Every Year Pest birds cause millions of dollars of damage annually to motor ...

  • Rainbow Environmental Services aims for Zero Waste with CP Group and Siemens

    Chase Clark wants to be a recycler with Rainbow Environmental Services when he grows up. The three-year-old boy loves nothing more than watching the collection trucks roll out of Rainbow’s Huntington Beach, California Material Recovery Facility (MRF) early in the morning. “Most of the drivers have gotten to know Chase, and they’ll honk their horns and wave on their way out for ...

  • Distributed Measurements Unlock the Future of Design

    The next generations of materials and design will require sensing technologies that can monitor beyond the scope of point sensors such as thermocouples and strain gauges. New sensing platforms based on optical fibers can obtain spatially continuous, real time data, giving developers detailed insight across broad areas into how their materials and designs behave. Such systems also can sense ...
