CEM - Abstract

Abstract Information :

EN14181 was published 2004, almost 20 years ago. During this period of time, the author has inspected the status on the Continuous Monitoring Systems at many different industries (Power plants, Cement plants, Incineration plants, Glass Plants, Aluminium Smelters, Chemical Industries, Fertilizer Industries, Steel Plants and so on). In doing so, several problems that most of the industries are facing has been identified, like: - There are 17 different administrations areas in Spain and each one of them do understand the European regulation in different ways, so they establish different requests to industries. Then similar plants (even within the same industrial group or company) located in different places have quite different administration requests, including: o How to validate data, even validation calculations, confidence interval, and uncertainties. o Reference materials, where to place or inject them (for example: some plants place the gas in the extraction probe and some other plants do it in the analyzer itself), how to use them, and how often to do it. o Data normalization: some plants are request to use peripherical monitoring and some others are not. When using peripherical monitoring, some places take care on some quality assurance levels and some other do not, including calibration (QAL2) and QAL3. o How to perform linearity in the functional test and what reference material to be used. - Data handling and reporting typical mistakes. - Typical maintenance errors. - Difficulties to fix broken systems and long time needed. - Etc. Facing all these problems, the quality assurance levels that industries set in their automated measuring systems are often very different from plant to plant and similar industrial process, with very similar emission levels may report, sometimes, very different data. Presentation will include case studies, and discussions on performance, data validation and results on final data.
