    Measurement solution for siloxane monitoring in biogas and landfill

    The generation of electricity from municipal digesters and land fill is of increasing interest, as the biogas can allow for a form of renewable energy. Organosilicon compounds often find their way into land-fill or digester gases as siloxanes. Siloxanes are low-level hazards to the atmosphere in terms of their emissions, however when they are combusted in gas engines the hard silica that is produced is very harsh to the moving parts of the gas engine.

    Gas analysis & monitoring system for greenhouse gases analysis

    The rising levels of manmade greenhouse gases (GHGs) in the atmosphere and their resulting impact on climate is now one of the single biggest technological and environmental challenges facing the world. This makes intensified monitoring of these gases more critical than ever in order to better quantify the role of the numerous natural and manmade sources, sinks and buffers involved in the cycles of GHGs. It also enables us to objectively audit GHG fluxes at the factory, city, country and continental level. Such objective auditing is ultimately essential to facilitate effective enforcement and compliance with any regulations, laws, treaties and trading agreements based on GHG metrics such as carbon footprints.

    Fluoride emissions monitoring in aluminum smelters

    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.

  • NDIR Carbon Dioxide (CO2) Monitoring

    Carbon dioxide has a wide range of commercial uses, from the production of lasers to the carbonation of soft drinks. This gas has become a topic of interest because it is classified among the greenhouse gases, gases which impact the Earth's environment when they reach high concentrations in the atmosphere. We propose solutions for medical diagnostics (out-breath control) and for ecological monitoring (control of carbon dioxide, exhaust gases in the atmosphere).

    Ambient air monitoring by FID detection – airmoVOC BTEX

    Urban pollution is a problem that concerns more and more people in charge of public health. In large cities, car emissions are an important source of atmospheric pollution. This problem is growing as the traffic keeps on increasing. BTEX compounds are present in car emissions. It is therefore important to be able to analyze them with short analysis cycle duration and on a continuous and automatic way.

    Ambient air and emissions monitoring of Polycyclic Aromatic Hydrocarbons – airmoC10-C20+

    Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently listed as priority air pollutants.

    Gas Detection Solutions for Liquified Natural Gas Detection

    Liquefied natural gas owners require improved routine monitoring of facilities for safety, economic and regulatory reasons. Leaking LNG can cause explosions leading to loss of life and property. Loss of product through undetected leaks dramatically reduces a pipeline operator’s profitability. Traditional gas detectors are slow to reach and require a labour intensive process to keep maintained. IR detectors have been used but with limited success because of cross interference from other atmospheric gases.

    Measurement solution for Perflurocarbon (PFC) emissions from aluminium industry

    The aluminium industry is the major source of perflurocarbon (PFC) emissions to the atmosphere, which are a major contributor to global warming. PFCs have greenhouse gas effects up to 10000 times that of CO2. Emissions have been reduced over the last 20 years, but further reductions are harder to achieve as all the mechanisms for PFC production are not known. In order to better understand the production of PFC on an industrial level, laboratory studies have been carried out using a small scale cell.

    Measurement solution for soil chamber gas flux

    Closed chamber gas flux measurements can be made with Protea FTIR analysers to allow researchers in the field of atmospheric gas analysis from agricultural and livestock to measure evolved gases such as N2O, CO2, CO, NH3, and CH4. Nitrous oxide (N2O) and Methane (CH4) emissions from soil, plant and livestock are especially important gases to measure, given their high potential as greenhouse gases (GHGs). NH3, whilst not a greenhouse gas on the scale of N2O, CH4 and CO2, is a major emission from agricultural, such as after the spreading of liquid manure, and steps are required to measure and reduce the NH3 emissions and the effects they have on the ecosystem.

    Measurement solution for to multi-stream by-pass system

    A large pharmaceutical plant runs a Thermal Oxidiser on plant to incinerate their solvent-containing gas streams before emission. When the oxidiser is offline, then the plant must monitor the release of solvent to the atmosphere. A ProtIR 204C fixed monitoring system was installed that continually measures 24 plant solvents, including Acetone, Cyclohexane, DCM, DMF, IPA, MIBK, Toluene and THF. Given the high levels that are possible, the system has an active dilution system, reducing the concentration of the measured gas in the analyser to levels that can be analysed simply. Chemometric modelling enables interferences from the overlapping absorption spectra to be accounted for, ensuring accurate analysis of all 24 gases.

    Gas monitoring instruments and systems for anesthetic gases

    The anesthetic gases and vapors which leak into the indoor atmosphere during medical procedures are considered waste anesthetic gases (WAGs). The exposure is of relevance to thousands of professionals in hospitals, operating theaters, patient recovery rooms, dental offices, and veterinary clinics around the world, who may be continually exposed to the waste anesthetic gases during their workday. Typical gases of concern include nitrous oxide N2O and several halogenated compounds in vapor form, such as sevoflurane, isoflurane, enflurane, halothane, desflurane, and methoxyflurane. Short-term exposure to these gases may lead to several symptoms, such as dizziness, headaches, fatigue, nausea. Long-term exposure to some of the anesthetic agents may result in sterility, birth defects, cancer, and liver and kidney disease.
