Combustion processes can be found all over the world: in refineries, the (petro)chemical industry and in power stations.
Inertisation and protection
Inertisation or blanketing is the process of filling the headspace of a vessel or reactor in order to protect it from explosion, undesired product degradation or polymerisation when oxygen and moisture are present.
Protect people and the environment
In industrial processes, oxygen measurement is crucial in preventing explosions. To this end, continuous real-time measurement is indispensable.
What is TDL?
A number of technologies may be used for the detection and analysis of specific components in a gas stream in environmental and process applications. These include gas chromatography, mass spectroscopy and chemo-luminescence. All these technologies have their own advantages and disadvantages. That is why Tunable Diode Laser spectroscopy, (TDLs), is now being increasingly used.
TDL analysers are very robust and therefore extremely suitable for inline gas analysis, even under high temperatures and pressure, or in corrosive environments without any sample preconditioning. One of the biggest advantages of TDL analysers is that there is almost no interference from other gases. Thanks to the increasing demand and potential applications, this technology has made significant technical progress. Owing to the use of semiconductor laser diode lasers and accurate tuning of the desired set of wavelengths, TDL analysers have become more sensitive and selective. Technical improvement led to higher stability resulting in less maintenance and long calibration intervals.
