Tasks
In the Technical Group "Emission Control" (former European Working Group "Flue Gas Cleaning") new installations of flue gas cleaning devices are a main point of discussion. For existing devices all techniques of flue gas cleaning are dealt with at furnaces for fossil fuels, biomass and wastes. (In furnace technical measures are not generally included.)
- SO2/SO3 emission reduction techniques (FGD); processes: Wet, limestone/lime based, spray absorption, dry absorption, proposed new techniques
- NOx emission reduction techniques (DENOX); processes: Selective Catalytic Reduction (SCR), Selective Non Catalytic Reduction (SNCR), proposed new techniques
- Dust precipitation / separation of FGD by-products, processes: ElectroStatic Precipitation (ESP), Fabric Filter (FF), emission reduction of aerosols, of particulate matter bound heavy metals
- Emission reduction of traces like HCl, HF, N2O, Corg + further gaseous traces by existing control equipment, and when required by further measures
- Decrease of internal energy consumption of emission reduction techniques
- Support process optimisation
- Analyse repair possibilities on cost and time requirements
- Analyse lifetime and possibilities of reactivation of components
- FGD waste water treatment aspects
- Recycling of waste water treatment sludge
- LCPD and IPPCD European and national requirements, technical realisation of legal regulations with system depending technical exceptions
- Analyse cost aspects of additional requirements
- Analyse new FGC techniques for LCPs, co-combustion of wastes in LCPs and for waste incineration plants.
- Check new process economics
- Analyse applicability of commercial available process additives
- Discuss regulation exceptions for start up, shut down and operational failure
