  • 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 ...

  • 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 ...

  • Detection and measurement of GWGs in semiconductor fab facilities

    Problem Statement Various processes and tools in the modern wafer fab plant produce effluent streams that contain unacceptably high levels of perfluorocarbon GWGs (greenhouse warming gases). These effluent streams are abated by plasma incineration and wet scrubbers and other techniques. It is necessary to measure the destruction removal efficiency (DRE) of the various abatement methods ...

  • Refrigerant leak detection is regulated by the US Environmental Protection Agency (EPA)

    Refrigerant leak detection is a difficult task in some heating ventilation and air conditioning systems or refrigeration and air conditioning systems. Sometimes the most experienced technicians find difficulty discovering a leak, which may be hidden in a system component, in tubing or in an operating or safety control switch. Refrigerant leak detection is a hot topic, following the recently ...

  • Why measuring the ambient NO2 without conversion?

    Nitrogen oxides NOx are pollutants that may have particular impact in terms of greenhouse gases, acidifying air etc ... issuance increased significantly since 1950 with the massive development of transport and industries. It therefore becomes necessary to provide measures always safer these pollutant gases, and to know the reliability of results. Currently, 60% of emissions of NO and NO2 are ...

  • 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 ...

  • Supercritical carbon dioxide – from coffee to dry cleaning

    Sometimes I can’t start the day without my morning coffee, and I’m sure most adults would agree that consuming caffeine is a part of their daily routine. A regular cup of coffee can contain 95 to 200mg of caffeine depending on what bean is used and how it has been prepared. In moderation, caffeine can elevate your mood, reduce tiredness and make you more alert, however it can also ...

  • Energy Conservation: Westpac Banking Corporation

    The concerted effort of employees was the key to the success of Westpac’s energy conservation program which, in 1994, reduced electricity bills by $2.54 million, more than recouping the initial outlay of $1.8 million in only the first year. In 1995, the bank outlayed another $1.1 million but saved an additional $1.5 million, increasing recurrent annual savings to $4 million. The program revolved ...
