Diode Laser Gas Monitoring Applications

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...

Process control and emissions monitoring in a mineral wool plant is a challenge due to the presence of phenol and formaldehyde. To use an extractive system in this environment will demand a lot of maintenance. The OPSIS DOAS system is different and provides plants with an accurate analyser that will operate with a minimum of maintenance. The OPSIS DOAS system is based on a non-contact method using an optical measurement path that can operate across the duct.

NH3 (Ammonia) is a colorless gas with a distinctive pungent smell. Ammonia monitoring is essential in coal-fired power plants, where NH3 is used to reduce NOx emissions. The ammonia consumes all of the NOx, but its high concentration that is needed for these purposes also starts reacting with other things and in the process can clog up filters and cause premature failure of expensive SCR equipment and pre-heaters. Not to mention that these high levels create an irreparable damage to the environment.

Hydrogen Fluoride (HF) is a colorless gas that is used extensively in industrial applications. Fluoride monitoring is especially needed for aluminum plants that need to convert HF into fluorine for use in their processes. Any HF that escapes is a cost to the plant, so an HF analyzer is essential to keep track of and prevent the losses.
