At the time of construction, the Alstom NID technology was new in the United States and no operating facilities larger than 100 megawatts were using this desulfurization method. The NID system eliminated the need for a spray dryer absorber, while successfully reducing sulfur dioxide and particulate-matter emissions.

of using a spray dryer as both an absorber and dryer simultaneously. Achieving this hinges on two crucial pieces of equipment – the GEA Niro rotary atomizer and gas disperser. The former atomises feed slurry into billions of droplets, while the latter ensures the correct gas dispersion to optimise drying and reaction conditions.

Overview of the lime-based spray dryer absorber. It is used when water consumption and sludge disposal restrictions are present. Spray dryer absorber (SDA) technology is observed to remove as much as 95% SO 2 from high sulfur coals, which is a characteristic reduction outcome for western low sulfur coals. It is a requirement that the SDA be upstream of a particulate …
