  • 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 ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • No more odor and corrosion case study

    Sewer systems are vulnerable to corrosion and, at times, can be the source of unpleasant odors. Kemira’s new H2S-Guard tackles both problems, as in most cases the source of these issues is hydrogen sulphide, forming in septic areas, in other words areas where no oxygen for metabolic reactions is available. The H2S-solution combines three important steps: measurement, monitoring and control ...

  • Monitoring gas mixtures in weld overlay cladding production - Case Study

    Arc Energy utilise the 542 binary gas analyser to monitor the mixture of gases in their weld overlay process. Arc Energy Resources was started by European Welding Engineer, Alan Robinson in 1994. Since then they have become a worldwide contractor of weld overlay clad products and services. Arc Energy’s weld overlay cladding provides heavy duty protection against corrosion and ...

  • Operating Principle of an Oxygen Monitor

    The oxygen concentration in the flue gas of a combustion process such as that of a power plant or a waste incinerator gives a good indication of the efficiency of the combustion process. The parameter is therefore of great interest to optimize fuel economy, but also to control and reduce emissions of air pollutants. An ideal combustion process only results in CO2 and water, but ...

  • Gas Safety in Confined Spaces

    Introduction An offshore worker ensures a vessel is safe to enter; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face common dangers, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited. A confined space ...

  • Combating Corrosion - Committee G01 Standards Fight Nature’s Destructive Tendencies

    The evening news may leave many of us feeling war-weary, but one ASTM International technical committee has been successful in conflict of a different sort. It’s a commonplace but epic struggle between the natural and civilized worlds — the fight against metal corrosion. For the past half-century, the weapon of choice of ASTM Committee ...

  • Gas safety in confined spaces

    An engineer repairs buried cables; a plant manager enters a small plant room; a contractor inspects the lining of a sewage pipe.  All these personnel face a common danger, despite working in widely different industries.  Gas-related injury poses a serious threat in any confined space where the free movement of air is limited.  ...

  • Compressed Gas Safety Guide

    Use and storage of any compressed gas under high pressure can be extremely dangerous if proper gas handling procedures are not observed. Moreover, chemical characteristics of specialty gases themselves can pose serious health hazards if containment is not tightly controlled. Paying close attention to a compressed gas product’s technical and safety information is invaluable for maintaining a safe, ...

  • Gas detector communication technology for offshore oil and gas platforms

    In few applications is safety as important as on offshore oil and gas platforms. Explosive hazards from hydrocarbon gases and vapours are an ever-present risk, whilst toxic hydrogen sulphide gas and depleted oxygen environments can pose significant risks to personnel. Gas detectors are therefore essential to provide dependable early warning of gas hazards. Gas detectors are permanently installed ...

  • Carbon dioxide gas case study

    Application Moisture] is measured in carbon dioxide gas pipelines and processing plants. Problem The presence of moisture in carbon dioxide gas promotes corrosion. Perhaps more significant is the fact that moisture will readily form ice when pressure is reduced. The ice can readily freeze up pressure regulators, valves, and orifice plates causing a loss of flow and even ice ...

  • Natural Gas Processing Case Study

    The Customer The Company is an exploration and production company that builds natural gas reserves through the acquisition and development of oil and gas assets across the U.S. They are one of the largest producers of natural gas in the Nation. The Process The Company uses multiple scrubbers to clean out the impurities of the natural gas that they ...

  • NEO Monitors conquers the Quasi-impossible

    China is a world factory powered by its abundant coal resource. China is facing a huge environmental challenge brought together with the fossil-fired power plants. China has therefore been conducting technical retrofit to the engines of its economy, by introducing emission control facilities. Selective Catalytic Reduction (SCR) technology is one of the most widely applied emission control ...

  • Gas Detection in Public Swimming Pool Facilities

    Recreational facilities’ indoor swimming pools provide a venue for exercise, competition and fun for all ages as patrons splash, swim, dive and float around in the crystal clear water. To keep the water fit to swim in requires a disinfectant maintenance program commonly using Chlorine, or Chlorine and Ozone. Chlorine is a powerful, corrosive disinfectant and in both gas and liquid forms it ...

  • Case study - N°AA3 – Ambiant air monitoring – WWP TRS MEDOR odor monitoring

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® ...

  • Gas cell selection for analysis of electronic gases

    APIMS and FTIR remain the preferred analytical tools for monitoring impurities in the electronic  specialty gases used by the semiconductor industry, although other tools such as CRDS are currently finding application in selected cases. FTIR spectroscopy offers the advantage of the simultaneous measurement of all gaseous species that exhibit dipole moment changes during vibrations at ...

  • The importance of maintaining your fixed gas analyser

    Plant technicians rigorously check for contaminates within the digester and ensure that the performance is optimised but maintaining the gas analyser monitoring the whole process is often overlooked.  Many analysers are used in harsh and potentially explosive environments and so it is of paramount importance that the operation runs smoothly and safely. With simple maintenance of your ...
