  • Detect Hydrogen Gas and Flames

    Under day-to-day conditions, people cannot see, smell, or taste the presence of hydrogen gas. Hydrogen, however, is very flammable and requires only a small amount of energy to ignite. In fact, if leaking from a pipe at a high enough pressure, hydrogen gas can self ignite without the aid of an external energy source. Working together, ...

  • Rehabilitation of Hydrogen Grooving in Sulfuric Acid Line

    Around October 2001, one of the major petrochemical refineries located on the Texas Louisiana Gulf coast needed to rehabilitate 6' and 8” diameter “fresh acid” (98% sulfuric acid) lines. Such lines tend to suffer from internal gouging due to formation of hydrogen gas in voids, which are caused by turbulence at directional changes in the pipe flow such as elbows, etc. This is a natural event, ...

  • Detecting Hydrogen Gas and Fires: Seeing the Unseen

    Hydrogen usage is growing. The general public sees and reads about hydrogen as an alternative fuel for cars. However, the big use for hydrogen is found in hydrocarbon processing and other important manufacturing processes. Hydrogen is the first element on the periodic table and is an essential element in the manufacturing of many of our everyday products. We must have respect for its explosive ...

  • Developing Technologies to Detect Hydrogen Sulfide (H2S) Gas

    Abstract Hydrogen sulfi de (H2S) gas can cause nausea, headaches, unconsciousness, and death. Industries struggle to detect this deadly substance before it harms workers or communities. Safety system manufacturers have developed detectors that sense the H2S quickly and accurately. This paper illustrates, in general terms, considerations in effective placement of H2S detectors: ...

  • Hydrogen-cooled electric generators case study

    Application Moisture contamination is measured in the hydrogen gas used to cool large stationary electric generators. Problem Hydrogen is used to cool the bearings and other rotating parts of large stationary electric generators. Hydrogen is the best choice for a cooling gas because of its unique combination of high thermal conductivity and low viscosity. In ...

  • Chlorine Safety and Prevention: How to Protect Yourself from Chlorine Leaks

    While chlorine gas is widely used in swimming pools, water treatment facilities, cleaning products, pharmaceutical products, and in many other industries, the gas is highly toxic when handled improperly. Training your workers on how to safely use chlorine is one part of health and safety best practices; monitoring your workplace for chlorine leaks is another. Learn about the hidden dangers in ...

  • Can I Purify Hydrogen from my HHO with a Metal Hydride?

    We occasionally get questions from people wanting to know if they can use a Metal Hydride (MH) to purify the Hydrogen from an HHO generator, so I thought I would post our response here: No   Why? ...

  • 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 ...

  • Is your Plant as tight as you think? Leak Detector for extremely toxic Gases, a Field Test Report

    Leak detection of commodity gases in chemical plants is a day-to-day practice. The sensor technology available for this application is field proven and reliable. No question about it, existing sensors will do the job. However, in plants manufacturing or handling extremely toxic substances, the picture is different. For example, take phosgene. The existing sensor technology for leak detection ...

  • Wastewater force main management – internal corrosion survey using inline methods

    In our first post about Wastewater Force Main Management, we looked at how preliminary analysis helps operators develop a plan for managing their system. After completing this process, operators can begin putting the plan into action with preliminary surveys on specific force mains. For those at WEFTEC, you can visit Pure ...

  • Controoling chlorine costs

    The most widespread disinfectant used in the treatment of drinking water is chlorine, which can be applied in a variety of ways. History has taught us that, in bacteriological terms, chlorinating water is a proven way of disinfecting drinking water. After all, more than 75 years have passed since chlorine was used to disinfect drinking water for the first time. Many years of experience have shown ...

  • Detecting Gases: What You Can`t Smell Can Hurt You

    Walking through a drill-site area, a worker smells rotten eggs and stops tor a minute or two to assess where a gas leak might exist. Rubbing his itchv eves as he investigates further, he notices that he no longer smells the tell¬tale hydrogen sulphide odour. He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose ...

  • VOCs Reduces Below Federal MCLs using HRC

    Summary Subsurface investigations at a dry cleaning facility revealed elevated levels of PCE and other regulated daughter products. HRC injection was chosen to accelerate the degradation of the entire range of VOCs. HRC slowly releases hydrogen, enhancing reductive dechlorination in an anaerobic environment. Additionally, HRC Primer, a less viscous version of HRC, was also used to reduce ...

  • The Langer Connection

    The call came from a Kennedy township homeowner that the smell of raw sewage was in the air and they were tired of the smell. Dave Gasparovich went out and started walking the very hilly area (15% grade or more) in search of the culprit. What he found was incredible, incredibly bad. The 12 manholes he discovered in the woods had been installed in the late 70’s and were connected with clay pipe. ...

  • Effective fight against unpleasant smell

    As part of a project for the neutralisation of hydrogen sulphide in the sewage system of a medium-size municipality, sera has started over ten innovative dosing systems in September 2008. An effective solution was developed in cooperation with an internationally operating water technology company. A municipality of approximately 50.000 citizens in the German state of North Rhine Westphalia was ...

  • PureAire Universal Gas Detector Offers Protection Against Toxic Levels of Ammonia

    In March of 2016, an ammonia gas leak at a seafood processing plant in Boston left one worker dead. The fumes at the plant were so powerful that firefighters could not promptly enter the scene to mitigate the gas leak and try to save the staff member until much later. Reports show that 5,300 pounds of ammonia gas leaked out of the plant. If you work with ammonia at your facility, learn ...

  • I think I smell sewer gas – what should i do?

    The first thing is to make sure the smell is sewer gas—usually a rotten egg smell—and not a natural gas smell—usually smells like a skunk. If you think it’s the natural gas smell, call the natural gas company immediately and if it’s anything but a very faint small—evacuate your home, office, or whenever it is—and wait for the gas company to give you an ...
