The Siemens LDS 6 laser gas analyser has been awarded a unique UK MCERTS certificate for gaseous HCl and HCl plus water vapour, adding to the company’s existing MCERTS certificate for the same product for NH3 and NH3 plus water.

Considered suitable for use in waste incineration and large coal fired combustion plant applications, the analyser is designed for both on-line and in-situ analysis, giving a continuous update of process data with real time measurements.

Shawn Pullman, product manager for Spectrometry at Siemens, commented: “MCERTS’ is the Environment Agency’s monitoring certification scheme, and it is an important framework within which to benchmark our work. Being awarded an MCERTS certificate for the LDS 6 is a great achievement and adds further credibility to our product range.” “Siemens are now being approached by many international Engineering Houses for our gas analyser range to carry an MCERTS approval.”

Operation of the LDS 6 is based on the concept that any light transmitting through a gas mixture will be absorbed only at certain narrow wavelengths. The light source in LDS 6 is a semi-conductor laser which is scanned in wavelength through an appropriate absorption line of the gas to be measured. The laser light is spectrally much narrower than the gas absorption line and this, together with a proper choice of absorption line, results in negligible interference from other gases.

The design of the LDS 6 analyser provides new possibilities for both the measurement of emissions and for process control. There are a number of significant advantages gained from the ability to obtain measurement signals in real time during the early stages of an incineration or similar combustion process.

The advantages of the system vary depending on the process in question, but through the use of this unique method, customers can expect to see increased efficiency and lower process maintenance costs, which down the line will also result in economic rewards and reduced impact on the environment.

Pullman continued: “In order for many businesses to release emissions to air, land or water, the company will be licensed by the EA and be obliged to install MCERTS certified analysers to monitor the process. The LDS 6 analyser brings not only an MCERTS solution but also a number of other benefits, including reduced maintenance periods and high availability as there is no need to re-calibrate, plus the LDS 6 can easily be incorporated as part of a retrofit program.”

MCERTS is the UK Environment Agency’s monitoring certification scheme. The scheme governs many businesses that make emissions to air, land and water and regulates them under a number of strict European and UK laws in order to protect the environment and UK health.
