Robust sulfur dioxide emissions monitoring
Evidence emerged that the standard test method for verifying compliance with the Industrial Emissions Directive might not be sufficiently accurate for targeted concentration levels to come into force.
Portable automated measuring systems (P-AMS) had inherent advantages for operators of real-time feedback but it was uncertain if these instrumental methods could be developed in compliance with the IED, since necessary quality assurance and control procedures had not been formulated.
The project Metrology for sampling and conditioning SO2 emissions from stacks clarified limitations of the existing SRM, proved the equivalence of instrumental methods, and led to the development of a new method for measuring SO2 concentration.
As a result, manufacturers of portable instrumental techniques may exploit new markets as emissions monitoring organisations embrace this less labour-intensive approach.
