Carbon Monoxide (CO) monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

Carbon monoxide poisoning is the most common type of fatal poisoning in many industrialized countries. Carbon monoxide is a colourless, odorless and tasteless gas caused by the incomplete combustion of hydrocarbon fuels. Carbon monoxide is a toxic gas to the human body, when inhaled it binds to hemoglobin, myoglobin, and mitochondrial cytochrome oxidase reducing oxygen storage, transport and respiration in these organelles.

Carbon Dioxide Monitoring for Indoor Air Quality

by Edinburgh Instruments Ltd     based in Livingston, UNITED KINGDOM

Introduction: Accurate control of critical indoor environmental parameters is not only essential for the well-being and comfort of building occupants, but also has a major impact on energy efficiency. A multitude of parameters can affect indoor air quality (IAQ) from gases such as carbon dioxide, carbon monoxide and volatile organic compounds to particulates, humidity and bacteria such as legionella. Carbon dioxide is one of the greatest variables affecting indoor environmental quality since it is produced by people occupying the building. Carbon dioxide production is a function of the number, size and activity levels of the people present in the building. Local concentrations can therefore vary dramatically – for example when a meeting room is occupied, or while workers are on lunch or coffee breaks.

CO2 / CO Monitoring in Air

by Unisearch Associates Inc.     based in Concord, ONTARIO (CANADA)

CO (carbon monoxide) and CO2 (carbon dioxide) are generally measured to ensure process control. CO2 is the desired product and CO is undesired in combustion since it will explode in high enough concentrations. CO2 and CO concentrations can also be used to determine other process-specific efficiencies. Continuous emissions monitoring equipment that can be calibrated as a CO and CO2 analyzer is thereby essential for process control.

CH4 Monitoring in Air

by Unisearch Associates Inc.     based in Concord, ONTARIO (CANADA)

CH4 (Methane) is a colorless, odorless natural gas that is used in a wide variety of industrial applications such as power generation and chemical production. It is also a byproduct of many biological and geological processes, fracking, and gas drilling. It is highly flammable and creates amounts of carbon monoxide as its combustion byproduct. Methane needs constant monitoring in waste water treatment (for co-generation) and to ensure proper process control (e.g. to determine burning efficiency). A quality CH4 analyzer that is able to provide continuous monitoring is a perfect solution for this.

Fluoride emissions monitoring in aluminum smelters

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In addition several fluoride compounds may be produced in the electrolytic bath in the event of an oxygen shortage. These compounds include carbon tetrafluoride CF4, hexafluoroethane C2F6, sulfur hexafluoride SF6, and silicon tetrafluoride SiF4. These additional emission components are problematic, as they have high Global Warming Potential (GWP) values. The GWP is a relative measure designed to demonstrate how much heat a greenhouse gas (GHG) traps in the atmosphere. Emission of one kilogram of carbon tetrafluoride into the atmosphere today has the potential of heating the atmosphere as much as 7,000 kilograms of carbon dioxide over the next 100 years.

Gas monitoring instruments and systems for compressed breathing air

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Compressed breathing air is subject to strict limits of harmful contaminants defined in European standard EN 12021 and various defence standards such as DEF STAN 68-284 issue 3. The testing interval of breathing air compressors and associated equipment is 3 months and gases tested include carbon monoxide, carbon dioxide and oil vapour defined as hexane and heavier hydrocarbons. EN 12021 covers underwater applications including self-contained open circuit compressed gas breathing (SCUBA) and compressed gas line breathing (hard-helmet diving), respiratory equipment used on ground for escaping from toxic atmospheres and for working in contaminated atmospheres. It also covers breathing gas for hyperbaric operations and synthetic air. While EN 12021 does not cover aerospace applications, the British MOD publication DEF STAN 68-284 and its counterparts in other countries cover also the breathing gases used in aviation.

Air Quality Monitoring Equipment for Combustion Industry

by Signal Group Ltd     based in Camberley, UNITED KINGDOM

Boilers and Combustion Research A fuel source burning with oxygen to produce carbon monoxide, carbon dioxide and water is an equation from school science lessons but looking into the fuel temperature and oxides of nitrogen produced along with the CO, CO2 and O2 is work that is being carried out by boiler makers, power generators and all sorts of industrial applications every day.

Gas monitoring instruments and systems for process NOx measurement

by Gasmet Technologies Oy     based in Helsinki, FINLAND

Nitric acid HNO3 is an important intermediate reagent for production of several important end products, such as fertilizers, explosives, dyestuffs/pigments, pesticides, pharmaceuticals, photographic materials, plastics, and synthetic fibers. At nitric acid manufacturing plants, the Gasmet™ FTIR Gas Analyzer can be used to measure several gaseous components from the process stream for purposes of process control. A single system can be used to measure the high levels of nitrogen monoxide NO and nitrogen dioxide NO2, as well as water vapor H2O, nitrous oxide N2O, carbon monoxide CO, carbon dioxide CO2 and ammonia NH3. The fixed installation products for these purposes are the Gasmet™ CEM II measurement system, and the Gasmet™ FCX Gas Analyzers, both of which utilize the FTIR measurement technique for simultaneous multicomponent analysis of the sample gas.

Excess CO2 levels can lead to tiredness and a lack of concentration and can contribute to the symptoms of Sick Building Syndrome such as headaches, eye, nose and throat irritation, itchy skin and nausea.
