Abstract
This paper assesses the results from a survey on how hydrogen chloride (HCl) in stack gas emissions from industrial processes is measured by organisations based in Europe that do periodic short-term measurements. The survey was done by asking organisations to complete a questionnaire.
The questions focused on the use of different monitoring techniques and the implementation of associated European monitoring methods (that is Committee of European Normalisation (CEN) standards).
The results of the survey showed that there are a variety of different approaches used throughout Europe for the measurement of HCl. The preference remains for the use of a wet chemistry method, as opposed to automated systems. However, the survey has shown that the approach to determining the uncertainty of the wet chemistry method varies between test laboratories with some using an uncertainty provided by the analysis laboratory and others using a fixed uncertainty provided in the CEN standard.
This work was part of a European Metrology Programme for Innovation and Research (EMPIR) project on “Determining new uncertainty requirements for increasingly stringent legislative HCl industrial emission limits” (18NRM04).
