  • Detection of moisture in ammonia gas

    Problem Statement As technologies advance, so does the request for ultra high purity ammonia. Ultra high purity (UHP) ammonia is used in the semiconductor industries, production of flat panel displays, and a number of other applications. Due to this rising interest in UHP ammonia, manufacturers are having to battle ammonia’s most prominent and damaging impurity--moisture. For ...

  • Indoor Air Quality and Hazardous Gas Detection

    Indoor air contaminants come in a variety of forms and originate from multiple sources. Interactions between building materials and furnishings, activities and equipment inside the building, internal temperature and relative humidity, filtration and ventilation system operations, climate and building occupants all contribute to the indoor air quality (IAQ) in commercial, industrial, residential ...

  • BUMP TESTING AMMONIA (NH3) SENSORS

    Bump testing a gas sensor involves flowing a concentration of gas that is slightly higher than the Low alarm setpoint of the gas detector for a short period of time (1-2 minutes or less). The purpose of a bump test is to confirm that the sensor responds to the presence of gas, the low alarm will activate and the gas detector overall ...

  • Fixed Versus Portable Gas Detection – Which Is Better?

    Did you know that workers are needlessly injured every year as a result of leaking toxic or combustible substances? Such incidents are known to involve a wide range of hazardous gases (including ammonia, carbon monoxide, chlorine, hydrogen sulfide, hydrocarbon vapors and so on). The sad reality is that most of these accidents are avoidable if only the workplace is adequately monitored. This leads ...

  • 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 ...

  • How to bump test and calibrate gas detection equipment

    Introduction ATEX, IEC, British HSE, and US OSHA standards all call for the bump test and calibration of any portable instrument used for worker health and safety protection in a potentially hazardous environment. In order to ensure safety it is necessary not only for the gas meter to read accurately but also ...

  • Pulp & Paper: Ammonia Emergency Plan calls on Packed Tower Case Study

    A few years ago Union Camp turned a corner. Management decided that advance planning would take the place of reacting after the fact to an emergency or regulatory agency demands. At Union Camp’s Dover, OH. facility, byproducts of the paper industry are converted into usable specialty chemicals for cosmetics, adhesives and other industries. Crystallization is a process used intensively ...

  • A Four Channel Gas Detector for Wastewater Treatment Plants

    Common hazardous gases found in wastewater treatment plant facilities are hydrogen sulphide, methane, ammonia, carbon monoxide, chlorine and oxygen deficiency. Some facilities may also use ozone, chlorine dioxide or sodium hypochlorite with the chlorine during the sanitization treatment process. Furthermore, sulphur dioxide is often used to de-chlorinate the water once the treatment process is ...

  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...

  • Fixed multi-parameter gas detection system can ensure industrial facilities are safe from hazardous or toxic gases

    Industrial workplaces are likely to come across one or more hazardous or toxic gases. Combustible gases such as methane are highly dangerous because they can cause large and fatal explosions when ignited. Other problem areas when working in industry are carbon monoxide (which poisons the cardiovascular system), oxygen deficiency, and elevated levels of other gases and pollutants, depending and ...

  • Analysis of greenhouse gas emissions from 10 biogas plants within the agricultural sector

    With the increasing number of biogas plants in Germany the necessity for an exact determination of the actual effect on the greenhouse gas emissions related to the energy production gains importance. Hitherto the life cycle assessments have been based on estimations of emissions of biogas plants. The lack of actual emission evaluations has been addressed within a project from which the selected ...

  • 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 ...

  • Effect of chemical oxidation on the gas sensing properties of multi-walled carbon nanotubes

    The effect of chemical oxidation on the gas sensing properties of multi-walled carbon nanotubes (MWNT) is presented in this paper. The MWNT were chemically oxidised in a mixture of concentrated sulphuric and nitric acids. The oxidation time was varied from 4 h to 12 h. X-ray photoelectron spectroscopy was used to study the effect on the chemical composition of the nanotube surface. The results ...

  • Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

    Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...
