  • Device for the production of solid aluminum chloride
    Patent number: 4334898
    Abstract: A device for producing solid aluminum chloride from gas containing gaseous aluminum chloride by means of a fluidized bed condenser. Between the inlet pipe for carrier gas and an outlet pipe for residual or waste gas there is a distributor plate with openings in the form of nozzles, at least one cooling facility, a feeding facility for the supply of gas containing gaseous aluminum chloride and a facility for drawing off the solid aluminum chloride. The outlet pipe for waste or residual gas is connected to the inlet pipe for carrier gas via a separator which separates out fine particulate aluminum chloride, which is then fed back to the bed to act as nuclei.
