CEM - Abstract

Abstract Information :

Today, the EU's Industrial Emission Directive (IED) sets emission limit values for installations based on the combustion of carbon based fuels (CHP, WtE, cement factories and other installations for the production of mineral materials). At the same time, this type of plants looks into the possibility of being the first plants on which it is logical to install CO2 capture plants. When CO 2 is removed from the flue gas that is emitted, the concentration of the pollution components will increase, making it impossible to compare with the EID emission limit values as they are defined today. With the speed at which CO2 capture is currently developing, it is not likely that the authorities and the EU will be able to develop new limit values for this type of plants. Therefore, Olicem A/S decided to develop a methodology which has made it possible to use existing limit values, even if CO2 capture facilities are established. During the journey towards the final solution, we have considered a number of different options. We consider the selected solution to be stable and usable, and it has been developed taking into account the use of existing measuring stations and expected requirements for AMS for determination of new components originating from the capture process. The presentation will be based on the first draft from the Danish Environmental Protection Agency, and contains proposed solutions based on: - Ease of use in relation to operating personnel - Limiting the number of measuring stations before and after the CO2 capture plant - Assessment of whether other plant measurements can be used for corrections - Are other measurement results available for quality assurance (of other measurements) The finally proposed solution will be presented, together with the relevant calculation formulas and the associated uncertainty estimates.
