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.
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.
Process control of a SO2 scrubber on a ship is a challenge due to wet and corrosive gases. In such environment, extractive gas sampling systems require high levels of maintenance in order to operate correctly. OPSIS monitoring system solves this by using an optical, non-contact, cross-duct technique. A light beam is sent across the duct or stack to be measured, and the captured light is sent through an optical fibre cable to an analyser. The analyser measures SO2, CO2 and NOx concentrations using UV and IR...
Determining levels of CO and CO2 and their respective ratio in the oxychlorination reactor contributes to overall process efficiency. The on-line analyzer system uses a selective CO/CO2 measurement by means of multi-wavelength infrared with automatic optical span possibility.
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).
Carbon Dioxide (CO2) lasers are high power lasers, usually used for cutting of ferrous and non-ferrous metals. High-performance gas flow control is a key requirement for achieving high cutting performance with CO2 lasers. Gas flow control plays an important role for mixing key gases at a number of locations with a CO2 laser: Beam Generation: The gas mixture used as the emitting medium usually consists of CO2, He and N2. Most laser manufacturers specify a minimum required purity for the beam generation gas...
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...
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.
Most large coal fired power plants and combustion processes are required to monitor CO, NO and NO2 (NOx), SO2 and possibly CO2; in addition the analyser has to be normalised to Standard conditions. For this application CODEL offers the five channel GCEM 40 series which uses Infrared absorption to measure these gases plus moisture, pressure and temperature. The analyser can be configured for single channel operation to monitor any of these gases plus CH4 and HCl.
