| Abstract Scope |
There is increasing focus on emissions and pollution. Currently aluminium smelters report on yearly basis, and averaged values based on measurements are sufficient. To meet stricter requirements and further reduce emissions, the industry needs systems for online emissions monitoring with predictive capabilities. The ambition should be to move from a reporting-after methodology, towards an online temporal and spatial representation of the emissions, both inside and outside the process areas and plants – in short, establish better measurements and emission models. Hydro and Alcoa are now cooperating with Cybernetica, Nemko Norlab, SINTEF and NTNU in a project called New Emissions Surveillance solutions for the Aluminium Industry – NESA. The overall system idea in the project is presented. Focus is then moved to pot room emissions, showing how sophisticated simulations can be represented by simplified models running significantly faster than real time. Finally, the links towards operations and dispersion modelling are explored. |
