Benzene (C6H6) Monitoring Articles

  • Air Quality Monitoring – BTEX Analyses

    Benzene is a hydrocarbon that appears as a volatile liquid, capable of evaporating rapidly at room temperature; it is colourless and easily flammable and is the progenitor of a family of organic compounds defined as aromatic, due to the characteristic odour. Benzene is a natural component of oil (1-5% by volume) and its refining derivatives. ...

  • How Refiners Use Monitoring Tools to Support Community Health and Safety

    Nothing is more important than the health and safety of our people and our communities—the communities where our employees live, work and go to school. Fenceline monitoring is used at our facilities to aid in the early detection of emissions, including benzene. The data helps us immediately correct problems and nearly all refining facilities quickly return to below action levels after ...

  • Risk Assessment and Brownfields: Determining Exposure to Site Contaminants

    The USEPA’s Brownfields Program USEPA’s Brownfields Program was established to facilitate the rehabilitation of contaminated property for redevelopment. EPA has set forth criteria that must be met before a revitalized property can be used for residential, commercial or industrial purposes. The focus of these criteria is the long-term protection of residents, employees or ...

  • Hidden Toxins In Your Air Freshener; Alternative Solution

    Household and workplace air sanitation has always been considered a key factor in productivity and happiness levels. Unpleasant smells from sinks, carpet stains, bins and Aircon filters have always stood in the way of the ideal clean-smelling home, office or even cars. Commercial advertisements advocate for a band-aid solution to the nasty smells using air fresheners in the form of sprays, ...

  • airmOzone: 88 VOCs from PAMS and TO14 lists - Case Study

    Ozone precursors by FID from WATER or AIR 0 - 325 μg/m3 or higher Context & Challenges Ozone concentration has been multiplied by 5 in the last century in the middle latitudes of the northern hemisphere from 10 PPB in 1874 to approximately 50 PPB today. This is an increase of 1.6% per year; the trend is probably higher (2.4% a year) over the last decades. (Chapter 1 of ...

  • The Role of Gas Detection in Offshore Applications

    Off-shore drilling is a highly hazardous process with dangers of complexes equipment, harsh environments, severe weather as well as toxic gases and volatile organic compounds (VOCs) which can be found mixed in with the products being extracted. Toxic gas emissions are a danger in the environments in which offshore applications are found, creating unsafe conditions for personnel. This results in ...

  • OGI Cameras for Environmental Regulation Enforcement - Case Study

    In Israel, the Haifa regulatory officials needed to know whether the local gas stations’ vapor recovery units were performing correctly. If so, they would be recovering much of the vapor that would otherwise be exhausted while refueling. If not, petrol stations faced losses from both lost product, and regulatory fines for pollution. After two weeks of using the EyeCGas, our investment was ...

  • What air quality in car parks?

    The quality of the air in the car parks is very variable. The main pollutants are often found above the recommended limit values, exposing the users but especially the operating personnel to health problems. This air quality varies according to three main parameters: The type of parking (overhead or underground) Traffic attendance and parking The type of ventilation (servo ...

  • Gas Chromatography: MCERTS Certification for Ambient Air Analysis on Benzene and VOCs

    Due to environmental issues, the world of gas analysis is evolving very rapidly.Governments set the rules to limit and control the environmental pollution through legislation.Volatile organic compounds (VOCs),often produced by human activities, are amongst the sources of pollution that need to be identified and quantified for safety reasons. Exposure to high concentrations of certain VOCs is ...

  • Risk Assessment and Contaminated Properties: Determining Exposure to Site Contaminants

    USEPA’s Brownfields Program was established to facilitate the rehabilitation of contaminated property for redevelopment. EPA has set forth criteria that must be met before a revitalized property can be used for residential, commercial or industrial purposes. The focus of these criteria is the long-term protection of residents, employees or visitors of a new facility. There are numerous ...

  • Health and Safety in Heavy Industries

    Many vapours and gases found in heavy industries pose an explosion risk. For any gas to combust it must reach its lower explosive limit (LELs). Lower explosive limits have been well established for 100s of chemicals and generally vapours from VOCs have relatively low explosion limits. For example, methane and hydrogen have LELs of 50,000 ppm and 40,000 ppm ...
