FOREWORD
Contributing a 73% share of the total amount of sulphur dioxide (SOz) and a 36% share of total nitrogen oxides (NOx) released into the atmosphere by European OECD member countries, large combustion installations represent an important source of these harmful air pollutants. In recent years, emissions of these pollutants from stationary sources have been limited through the installation of advanced S02 and NOx emission control technologies. In OECD Europe, the most commonly-used technologies for S02 and NOx control are the wet scrubbing and the selective catalytic reduction processes, respectively, but a variety of different techniques are currently in use. Due to country-specific or plant-specific conditions, even the most common techniques have been employed in different ways, resulting in a large body of specific operational experience and in the optimisation of several of the processes. In spite of the considerable development undergone by these technologies, however, implementation remains limited and vast possibilities for emission reductions are unexploited. In some Member countries of OECD Europe, for example, the further reduction potential for S02 has been placed as high as 90%.
While those emission control technologies still in the research and development stages are not considered, this report examines the best current technologies, combining in-depth technical and financial analyses of the various processes in use with detailed accounts of specific operational experience. These accounts have been compiled from on-site discussions at a representative sample of large combustion installations throughout Europe.
