  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • Sonic nozzles for gas calibrators, when simplicity provides accuracy!

    Gas analyser’s calibration is a task required in many applications according to either legislation or quality systems management. This is the case for Air Pollution Monitoring or Continuous Emissions Monitoring devices installed in cabinets, for continuous analysis in remote locations. Measurements in traces range are performed and analytical devices specifications need to be validated and ...

  • Validation and calibration of a spectroscopic technique for determination of gas plume temperature

    Abstract Results are reported from a continuing program of research into the physics and spectroscopy of heated stack plumes. Simultaneous thermocouple and spectrometer measurements are used to study sideways—directed plumes from an internal combustion engine and a propane-burning plume generator. A previously-reported result, that the ratio of optically thin signals from two CO2 ...

  • Primary Standard Gas Flow Calibration—The Only Guarantee of Accuracy

    At Sierra, we have a saying: “An instrument’s accuracy is only as good as its calibration.” The accuracy of your mass flow controller (MFC) is essential in assuring the efficiency, performance, and quality of your flow meter. In many cases, if your instrumentation is not calibrated, then a decline in performance is possible due to ...

  • A simple radon chamber for use with soil gas for calibration of radon measuring devices and instruments

    A simple and easy to use radon calibration chamber of volume of 216 litres was designed and constructed for applications in calibration of radon measuring devices and for research studies. The main advantage of this chamber is that instead of using 226Ra source to generate the 222Rn inside the chamber, ...

  • 5th-Generation Thermox WDG Flue Gas Combustion Analyzer

    "For more than 40 years, we have been a leader in combustion gas analysis," says Mike Fuller, divison VP of sales and marketing and business development for Ametek Process Instruments, "and we believe the WDG-V is the combustion analyzer of the future." WDG analyzers are based on a zirconium oxide cell that provides a reliable and cost-effective solution for measuring excess oxygen in flue gas as ...

  • Gas safety in confined spaces

    An engineer repairs buried cables; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face a common danger, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited.  ...

  • Integration of mathematical and physical simulation to calibrate car-following behaviour of unimpaired and impaired drivers

    Traffic patterns can be modelled by mathematical microsimulation. People can be modelled by driving simulators that resemble flight simulators. This paper shows how driver car-following behaviour from driving simulators can be transferred to traffic microscopic simulation. We capture driver behaviour through physical driver simulator experiments. Subjects holding cell phone conversations while ...

  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • PureAire Makes Oxygen Monitor for Nitrogen Generators

    Nitrogen generators are most commonly used in areas where on-demand nitrogen is preferred rather than, storing liquid nitrogen (LN2) in cylinders.  Nitrogen generators have a lower cost of operation, and can be used where smaller amounts of nitrogen are needed. Nitrogen generators are used in the pharmaceutical industry, testing laboratories, cryogenic facilities, welding manufactures, and ...

  • Hydrogen-cooled electric generators case study

    Application Moisture contamination is measured in the hydrogen gas used to cool large stationary electric generators. Problem Hydrogen is used to cool the bearings and other rotating parts of large stationary electric generators. Hydrogen is the best choice for a cooling gas because of its unique combination of high thermal conductivity and low viscosity. In ...

  • Nitrogen Generators: Where are they Installed and How to Stay Safe?

    Used in a range of industries, nitrogen generators ensure a steady supply of 99.5% pure, commercially sterile nitrogen from a compressed air storage tank. From an industrial standpoint, nitrogen generators are seen as preferable to cylinders of nitrogen as they are more reliable, more compact, and easy to use and install. However, these generators ...

  • NovaGerar landfill gas to energy project

    Overview The objective of the NovaGerar Landfill Gas to Energy Project in Nova Iguaçu - Rio de Janeiro, Brazil is to explore the landfill gas (LFG) collection and utilization activities of the landfills managed by S.A. Paulista. This involves investing in a gas collection system, leachate drainage system and a modular electricity generation plant at each landfill site (with expected ...

  • CO2 Gas Hazards in the Brewing Industry

    The hazards associated with CO2 in the brewing industry are well known, yet people still die needlessly every year in tragic and completely avoidable accidents in breweries. Just last year in Germany, which has a good safety record, two workers died in separate incidents at the same brewery. In the first incident, the owner was found dead with his head and torso in a beer mixing tank. It is ...

  • Gas detector communication technology for offshore oil and gas platforms

    In few applications is safety as important as on offshore oil and gas platforms. Explosive hazards from hydrocarbon gases and vapours are an ever-present risk, whilst toxic hydrogen sulphide gas and depleted oxygen environments can pose significant risks to personnel. Gas detectors are therefore essential to provide dependable early warning of gas hazards. Gas detectors are permanently installed ...

  • Danger and Detection of Hydrogen Sulphide Gas in Oil and Gas Exploration and Production

    A rig worker smells rotten eggs near the well head, rubs his itchy eyes as he investigates the frosty pipe connections. After a few moments, he believes all is fine as he no longer smells the tell-tale hydrogen sulphide odour. In this scenario, we can only hope the worker recognises the danger and quickly leaves the site. Oil fields, especially mature ones, can produce hydrogen sulphide gas ...

  • 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 ...
