  • Study of vehicular emissions with reference to Pakistan's National Environmental Quality Standards: case study of District Swat, North of Pakistan

    This study was conducted during 2011–2012 with the objective to assess the ambient air quality in the surroundings of a newly constructed road in relation to Pakistan's Environmental Quality Standard (Pak–NEQS). The area was monitored twice, before and during the construction, to determine levels of sulphur dioxide, nitrous oxide, carbon monoxide, and PM10 (particulate matter). A ...

  • Put energy into emission control projects

    Many companies feel pressured to spend the least amount possible to meet environmental regulations, primarily because compliance isn’t a profit generating endeavor. What some environmental and compliance managers fail to realize is that emission control equipment can quickly become a profit decreasing endeavor with this penny wise-pound foolish approach. With mandatory greenhouse gas (GHG) ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • Advanced gas analysis - on the go

    The field of ambient air analysis - monitoring industrial and other environments for harmful concentrations of gases - has traditionally faced a technology limitations: Would you prefer a complete and reliable tool, which will be bulky, complicated and inconvenient? Or would you like a nice portable one that's simple and lightweight, but unreliable and limited in its capability? Truly complete ...

  • Case study - Amine tail gas treatment

    COVERING YOUR TAIL GAS The discovery of new shale formations throughout the world and the development of new drilling technologies have increased natural gas production and prompted government agencies to instigate tighter air-pollutioncontrol regulations on processing operations. Unfortunately, meeting environmental regulations is not a profit-generating endeavor. Simply put, the time ...

  • National Air Pollutant Emission Trends, 1900-1998

     Executive Summary What information is presented in this report? This report presents the United States (U.S.) Environmental Protection Agency’s (EPA) latest estimates of national emissions for criteria air pollutants: carbon monoxide (CO), nitrogen oxides (NOX ), volatile organic compounds (VOC), sulfur dioxide (SO2 ), particulate matter (PM) less than 10 ...

  • 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 ...

  • 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 ...

  • The tailoring of greenhouse gases to the clean air act – challenges for PSD and title v permitting ahead?

    In anticipation of the promulgation of Clean Air Act (CAA) regulations to control greenhouse gas (GHG) emissions, EPA published the proposed PSD and Title V GHG Tailoring Rule. The proposed GHG Tailoring Rule was published in the Federal Register on October 27, 2009 and has a 60-day public comment period; thus comments are due by December 28, 2009. The proposed GHG Tailoring Rule attempts to ...

  • The shifting sands of GHG regulation

    So far this year, there have been significant developments on U.S. climate change policy, including movement toward mandatory reporting and regulation of greenhouse gas (GHG) emissions at the federal level via either a cap-and-trade program or possibly existing Clean Air Act mechanisms. While the specifics are still uncertain regarding how these regulatory developments and legislative actions ...

  • SGBI opinion article: shale gas

    Government perceives electric vehicles to be a panacea that will solve problems surrounding air quality and CO2 emissions simultaneously. The EV has two main selling points: reduced CO2 emissions and high efficiency. However, these are only valid at a superficial level and the argument disintegrates under any level of scrutiny. In terms of CO2 emissions, EVs replace ‘average’ cars to ...
