Research-Cottrell is the exclusive worldwide licensee for Alcoa's A-398 and A-446 fluidized bed dry scrubbing technologies. The technologiesthe basis for the new MACT rulesprovide state-of-the-art emission control and fluoride recovery from both primary aluminum potline and bake oven applications. A-398 systems are currently installed on more than 20 smelters (56 potlines) worldwide, treating over 20 million cfm of potroom gases from both prebake and Soderburg-type reduction cells. The A-398 and A-446 technologies routinely achieve greater than 99.9% fluoride removal efficiencies. In addition to controlling fluorides and particulate, the A-446 scrubbing process significantly reduces hydrocarbons (Tars, POM, B(a)P) and SO2 emissions from bakeoven furnaces, without a separate spray cooling chamber. Alcoa's proven fluid bed scrubber systems and Research-Cottrell's vast air pollution control experience in fabric filter, electrostatic precipitator, wet and dry scrubber, and VOC-removal technologies, combine to allow Research-Cottrell to offer the "Best" technologies at a competitive price.
