  • Advanced gas detection technology supports arctic greenhouse gas research

    Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital because melting of permafrost could cause a dangerous climate tipping point. There can be few more challenging environments for monitoring gases, but PhD researcher Martin ...

  • Exhaust gas treatment by an atmospheric pressure microwave plasma

    A microwave process for treating exhaust gases from internal combustion engines is presented. The exhaust gases are ionised by microwave energy at 2.45 GHz and the resultant plasma jet discharges into ambient air and exhaust gas environment. A gas analyser was used to measure the change in exhaust gas composition due to the influence of the plasma. Large decreases in CO2, CO and hydrocarbon ...

  • 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 ...

  • Analysis of Natural Gas Products by GC / TCD / FID

    The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific Model 910 ...

  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

  • Gas Monitoring for Ventilation Control and Energy Management

    The growing demand for underground and enclosed parking and maintenance garages (resulting from limitations on land availability) has increased the awareness and need for proper ventilation and control systems. In addition, increased health and safety programs have only added to the concerns of toxic and combustible gases in confined or enclosed spaces. Historically, ventilation and make-up air ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...

  • Calculating Accidental Release Flow Rates From Pressurized Gas Systems

    When determining the consequences of accidental release flow rates from pressurized gas systems, it is important to select the appropriate type of air pollution dispersion model. For released gases which are lighter than or equal to the ambient air density, Gaussian dispersion models as described in Beychok's text1 should be used. For released gases which are heavier than air, a dense gas model ...
