Raw Gas Analysers

Continuous emission monitoring to improve control, operation and efficiencies

Process Gas Analysers

Gas Solutions using an extractive method are particularly appropriate for Process Control application as the gas analysers are not directly exposed to often very difficult and challenging conditions.

All our raw gas analysers are designed for continuous operation and suitable for a wide range of industrial applications.

Raw gas measurements can be extremely valuable to operators, be it for combustion control, monitoring of sulphur or chlorine content of fuel or monitoring efficiency of abatement plant (e.g. lime or bicarb. dosing, SCR SNCR).

A well-considered measurement can optimise performance, highlight when a plant or fuel is out of spec. and reduce the consumption of reagents. As a benefit to a plant / operator, a ‘pay back’ time on investment can be very short for such devices.

All of our Raw Gas analysers are designed for continuous operation and suitable for a wide range of industrial applications. We use a combination of in situ and extractive devices based on our many years of experience. Where appropriate we recommend additional measures (coatings / deflection plates / blow back) to prolong the life and optimise reliability of such installations.

If you have any questions or would like to find out more about our range of raw gas analysers, please contact our friendly team online today and we’ll provide all the information you require.

Typical applications are:

Delta CO (carbon monoxide) measurements for monitoring smouldering fire, e. g. in coal mills, coal silos or baghouse filters
Delta NO (nitric oxide) measurements for denitrification plants control
NH₃ (ammonia) latency measurements at SCR / SNCR systems
HCl (hydrogen chloride)- and SO₂ (sulphur dioxide) measurements in raw gas for the flue gas cleaning systems / desulphurisation plants control
VOC measurement
O₂ (oxygen) measurement for monitoring inerting systems in chemical and pharmaceutical industries.

How do our UVA products operate?

Our devices are composed of light sources, measuring cells and a spectrometer which are all interconnected via an optical path. The emitted radiation is absorbed by the process gas in the measuring cell and is then detected by the spectrometer. This can then determine concentration of the gas. The UVA 17 uses Ultraviolet spectroscopy to measure absorption of the gaseous components of interest.
