Drawing from 30 000 MW of world-wide FGD experience, ABB has developed a system designed to reduce the overall cost of SO2 compliance. The advanced wet scrubbing system is being demonstrated at Ohio Edison's Niles Plant at the 130 MW level. In the development work ABB has put a lot of effort into understanding of the two basic processes that determine the size of a wet FGD system, i.e. gas-liquid mass transfer of the droplets in the spray zone and the impact of various process parameters on the dissolution rate of limestone. This paper present the derived models and the results both in terms of scientific qualitative results but also how these results have been implemented into ABBs advanced WFGD system design.
