  • Gas Dilution With The Equal Capillaries Technique

    The advantages of the equal capillaries technique are surprising and leads to reach accuracy values of one order of magnitude higher than all the other dynamic dilution techniques. This comparison will be supported by analyzing the accuracy available with two different techniques. Nozzles (sonic or non-sonic) technique With this technique, a series of different size nozzles is used ...

  • Alternative Solutions to Helium

    Helium is well known as Helium that makes balloons and airships float and in its liquid form, Helium is used in a variety of applications including cooling for magnets in Magnetic Resonance Imaging (MRI) scanners, cooling infrared detectors, and as a superconductor coolant in the large hadron collider at CERN. Helium is distilled from natural gas deposits that have collected in the presence of ...

    Quantum dot infrared photodetectors (QDIPs) have been shown to be a key technology in broad infrared wavelength (3-12 µm) detection due to their potential for normal incidence operation, low dark current density and higher temperature operation. In our research, we have been investigating infrared detectors based on intersubband transitions in a novel InAs/In0.15Ga ...

  • Functionalised multi–walled carbon nanotubes for chemical vapour detection

    Oxygen plasma functionalised Multi–Walled Carbon Nanotubes (MWCNT) were used to prepare gas sensors that can operate at room temperature. Alumina substrates with interdigitated gold electrodes were employed as transducers and the air–brushing method was used to coat them with carbon nanotube film. Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) images of deposited ...

  • The Drumbeat on infrared thermal imaging

    Drumbeat Energy regards infrared (thermal) imaging as an amazingly useful tool in the quest for greater energy efficiency. It has the ability to define non-invasively and with uncanny speed and accuracy where heat is leaking from a building. Never was the expression “A picture paints a thousand words” ...

  • What comes to mind when you think of `global warming?`

    In the past decade, the images and feelings Americans associate with the term "global warming" have shifted dramatically. Researchers at the Yale Project on Climate Communication recently published an article in the journal Risk Analysis that identifies and analyzes these shifts in the connotative meaning of "global warming." The most striking result is the increase in the proportion of Americans ...

  • Three–dimensional pore networks and transport properties of a shale gas formation determined from focused ion beam serial imaging

    Three–dimensional pore network reconstructions of mudstone properties are made using dual focused ion beam–scanning electron microscopy (FIB–SEM). Samples of Jurassic Haynesville Formation mudstone are examined with FIB–SEM and image analysis to determine pore properties, topology, and tortuosity. Resolvable pore morphologies (>~10 nm) include large slit–like pores between clay aggregates and ...

  • 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 ...

  • GEM condensate return system projects

    Most of the Coca-Cola consumed in Northern Ireland comes from the company’s Lambeg bottling plant. An assessment was conducted on the steam trap needs for the water heater of the company’s large bottle washer and bucket tests showed variable flow up to a quarter of a tonne of steam per hour. The two inverted bucket steam traps in the system were proving unreliable, so they were replaced with two ...

  • 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 ...

  • Advances in gas control technology in the brewery

    The use of nitrogen as a process gas, foam enhancer and flavour modifier has come to the fore over the last 10 years, with dissolved gas specifications becoming more stringent. Increasingly, marketing and consumer requirements for a targeted product identity or image have to be met, not only for taste but, perhaps equally as importantly for the consumer, ...
