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...
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.
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 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...
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.
Typical supported applications are industrial emission monitoring and gas manufacturing control. Focuses on medium NOx, NOx-related and multigas-concentrations up to 5’000 ppm where flexibility is a central requirement. Parameters included are NO, NO2, NOx, NH3, NOx-amines, O2 and CO2. Typical supported applications are industrial emission monitoring and gas manufacturing control.
If you use compressed breathing air it is essential to monitor for contaminants including carbon monoxide (CO), carbon dioxide (CO2) and volatile organic compounds (VOCs) as well as oil mist and water vapour. Some people spot-check their compressed air quarterly using colorimetric tubes, but it is safer to test the air continuously. If you are operating or servicing equipment containing fluorinated greenhouse gas (F gas) in refrigeration, air conditioning and fire protection systems you need to adhere to requireme...

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...
“Biogas” means a mixture of various types of gas (mostly methane) produced by bacterial fermentation in anaerobic conditions(absence of oxygen) of organic residues from waste, decaying plant, carcasses in putrescence. The analyzers of biogas by Infrared cells carry out the continuous analysis of CH4, O2, CO2, H2S and NH3. The whole process sees the decomposition of organic material by some types of bacteria, producing carbon dioxide, molecular hydrogen and methane(methane conversion of organic compounds...
QCAL introduces CO2Control for incubators and test chambers. These gas dosing units can be adapted to nearly every incubator or test chamber. The user can set a CO2 concentration up to 30% vol. CO2. The CO2Control measures the actual concentration and adds CO2 from a CO2 gas container. The NDIR CO2-sensor has an excellent long-term stability, which provides years of stable CO2 measurement. Also the other parts as the sample gas pump, valve and fittings are designed for maintenance-free use over years.
