  • Benefits of HART Communication-Enabled Gas and Flame Detectors

    Catastrophic results can occur when a fire or a flammable/toxic gas release goes undetected in any petrochemical facility. For early warning and prompt hazard mitigation, flame detectors and gas detectors are essential tools. Clear, usable, diagnostic information from these detection instruments is extremely valuable in ensuring the devices are properly maintained, tested, and poised to protect ...

  • FTIR gas analysis improves container safety

    Introduction Entry to freight containers represents a significant hazard to staff responsible for inspection, stuffing or destuffing because of the large number of airborne chemicals that can be present. Research in Germany and the Netherlands found hazardous levels of gases and vapours in around 20% of all containers and this level of contamination is now accepted as commonplace. It ...

  • Identifying Leaks from Natural Gas Pipelines at a Safe Distance

    The use of natural gas, of which methane is the principle component, is increasing worldwide. According to the American Petroleum Institute methane meets 24% of U.S. energy demand and heats over 50% of all U.S. households. It also has many industrial uses, such as the manufacture of chemicals like ammonia, methanol, butane, ethane, propane and acetic acid; it is also an ingredient in products as ...

  • An Assessment of the Impact that Gas Monitoring Practices Can Have on “Cost of Ownership” and “Return on Investment”

    Consideration and discussion are devoted to the notion that “gas monitoring instrumentation should be treated just like any other piece of lifesaving equipment…”1.  This is especially true for the semiconductor, photovoltaic, and gas manufacturing industries, where even the tiniest of impurities can wreck economical havoc on a plant, including loss of product, ...
