Abstract
The aluminum fluoride synthesis according to the Lurgi process is operated in two stages with circulating fluidbeds in the reactor with recycling cyclone and in the subsequent Venturi reactor. Liquid HF and partly dehydrated Al(OH)3 are used as feed materials. The flow sheet and operation experiences of a 30 tpd plant are discussed.
