摘要

Hooded pots, with pre-baked anodes allow gas collecting efficiency up to 98 percent. Gas cleaning accomplished by dry scrubbing and recycling of fluorides in pot gas. The ASV dry scrubber/reactor is in the commercial development stage. The main objective of the reactor is to increase the residence time of the gas/alumina and thereby reduce the amount of alumina needed in the dry scrubber. The system effects almost complete removal of the solid and gaseous fluorides collected from the pot gas. At the same time, other particulates, such as alumina, carbon etc. are also removed.
