co2 monitoring Applications

  • Carbon Dioxide (CO2) monitoring

    Carbon dioxide (CO2) is emitted in a number of ways. It is emitted naturally and through human activities like the burning of fossil fuels. Carbon dioxide (CO2) is generated as a by-product of the combustion of fossil fuels or the burning of vegetable matter, among other chemical processes. Small amounts of carbon dioxide are emitted from volcanoes and other geothermal processes.

  • CO2 / CO Monitoring in Air

    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.

  • 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).

    Measurement solution for CO2 capture by amine absorption

    The act of capturing and storing CO2 produced from large scale combustion plants such as power stations is becoming more and more favourable and feasible. One of the most common post-combustion CO2 capture methods is by absorption. The absorption plant can be added on to the existing combustion process, with the flue gas first passing through an absorption column where the CO2 reacts with an absorber. Amines of different types are used as the absorber. An amine CO2 capture plant can capture as much as 90% of the CO2 emitted from the power station and so has a real benefit for the environment. Having said this, care needs to be taken to ensure that amine emissions themselves are monitored, managed and prove no extra damage to the environment. Research is on-going to develop new amines or mixtures of amines to reduce emissions. The most common absorber in use in today’s first generation of industrial pilot plants is Monoethanolamine (MEA).

    Continuous emissions monitoring for CO2 capture

    The process control of a CO2 capture plant needs good and reliable detection of gas phase NH3 and CO2. Measuring NH3 is a challenge due to the corrosive environment and high concentrations of NH3. Several places in the process needs to be monitored and to transport the sample is difficult. A large dynamic range is needed as the NH3 concentration can vary between 15% volume and a few mg/m3.

    Measurement of acetaldehyde, methanol, & benzene in CO2 applications for gas manufacturers & food & beverage industry

    The BevAlert Model 8900 provides direct measurement of Acetaldehyde, Methanol, and Benzene (AMB) in Carbon Dioxide. The instrument is utilized by Specialty Gas Manufacturers and the Food and Beverage Industry to monitor trace impurities in CO2 used in carbonated beverages. The BevAlert Model 8900 employs a photoionization detector (PID). The AMB in the gas sample are physically separated using proprietary GC columns. A dual-column configuration with timed backflush to vent is used to strip off moisture and heavier gases. At sample injection, a fixed volume of sample is carried through the pre-cut column. The backflush is timed so that primarily the AMB and other similar compounds continue on to the analytical column. Contaminants are then backflushed to vent. Acetaldehyde, Methanol, and Benzene are separated from potentially interfering components on the analytical column and elute to the detector for analysis.

    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.
