  • Air crash investigation using Oxford Instruments handheld analysers - case study

    It was late April 1945 during the last days of World War II for Italy. Just one week before the liberation of Italy from the fascists rule, a group of five Messerschmitt BF 109 planes took off from the Vicenza airbase heading to Ghedi, near Brescia. This was not a combat mission but a transfer flight. Soon after take-off the planes were intercepted by US fighters and attacked. All five planes ...

  • Argon Gas, 3D Printing, and How to Stay Safe

    For the average person, Argon gas is not a topic of daily conversation, or, for that matter, any conversation, ever. It may be surprising to learn that argon is the third most common gas in the earth’s atmosphere, though most people know little about it. The word argon itself comes from a Greek word meaning ‘inactive’ because of its lack of chemical reactions. Argon is ...

  • Model 5100 Verification/Validation case study

    Background Many sensors used in gas analyzer systems come into direct contact with the process gas, and there is the potential for degradation over time especially with streams that contain contaminants like glycol, moderate to high levels of hydrogen sulfide etc. With sensor degradation, the analyzer response characteristics change resulting in inaccurate readings. In order to ...

  • Low level moisture measurement in Natural gas using a Lunable diode laser absorption spectroscopy (tdlas) based laser case study

    Introduction The measurement of water vapor in natural gas has long been of industrial importance, and has been addressed by a variety of analytical techniques over the years. Chief among these techniques has been the quartz crystal microbalance (QCM) based analyzers. The QCM technology is still the workhorse for production and pipeline applications, and the technique is considered by most ...

  • Measurement of a Doubly Substituted Methane Isotopologue, 13CH3D

    ABSTRACT: Methane is an important energy resource and significant long-lived greenhouse gas. Carbon and hydrogen isotope ratios have been used to better constrain the sources of methane but interpretations based on these two parameters alone can often be inconclusive. The precise measurement of a doubly substituted methane isotopologue, 13CH3D, is expected to add a critical new dimension to ...

  • On Line Measurement of Oxygen: Review and New Developments

    Keywords Oxygen. Paramagnetic, Zirconia, Tunable Diode Lasers Abstract Oxygen is vitally important to the existence of animal life, not only for respiration, but also for the many aspects of the combustion reaction (power generation, vehicular movement, heating) and process control, safety and quality. Continuous measurement techniques are correspondingly ...

  • Laser gas detector systems for greenhouse gas emissions monitoring

    Two types of portable laser based gas detector for measuring emissions of the greenhouse gases carbon dioxide (CO2) and methane (CH4) from oil and gas operations are described. A scanning open path detector was developed within a Cooperative Research and Development Agreement (CRADA) with the USEPA. This system scans multiple paths across an area source in rapid succession, enabling calculation ...

  • Portable laser gas detector systems for landfill CH4 and CO2 monitoring

    There has recently been a marked increase in interest in detecting and quantifying emissions of the greenhouse gases (GHG) carbon dioxide (CO2) and methane (CH4) from landfills in North America and Europe. The primary drivers for this increased interest are: new and pending legislation requires demonstrated reductions in GHG emissions; permits to expand existing facilities require more accurate ...

  • Fluoride Emission from Anode Butts in a Cooling Tunnel

    Abstract Nordic Aluminium has been trying out a cooling tunnel for hot anode butts in order to lower the fluoride content of the working environment. The cooling tunnel is connected to the Fume Treatment Plant so that it has forced suction from it. The purpose of this study is to evaluate the effectiveness of the tunnel in removing HF emissions and make suggestions on how to make the tunnel ...
