The European Community has published several directives like the Large Combustion Plant Directive (LCPD, 2001/80/EC), Industrial Emissions Directive (IPPC, 2010/75/EU) or the Waste Incineration Directive (2000/76/EC) to harmonise the legislation on industrial emissions, in order to achieve a high level of protection for the environment and human health. Comparable efforts are being undertaken all over the world.
The European Standard EN14181 describes the quality assurance procedures for CEMS in meeting the uncertainty requirements on measured values given by legislation. EN14181 had far-reaching consequences for regulators, equipment manufacturers, test houses and process operators. Three different Quality Assurance Levels are described – QAL1 for verifying the suitability of a system to its measuring task, QAL2 for the validation of the system following the installation in a specific plant and QAL3 for verification of control while operating.
The company Axetris (Switzerland) offers an extractive TDLS solution, a pre-calibrated OEM module carrying out a hot-wet measurement, e.g. ammonia and humidity at 190°C. The technology increases performance, reliability and cost effectiveness - or simply enables new opportunities for OEM customers. The LGD F200-H NH3 module can be used for a certification range of 0 - 10 mg/m3 NH3 (lower range) and 0 - 30% vol. absolute humidity.
