摘要： A gas cleaning unit for cleaning an effluent gas of at least one aluminium production electrolytic cell comprises a contact reactor in which the effluent gas is brought into contact with alumina, and a dust removal device for removing at least a portion of the alumina. The gas cleaning unit further comprises a wet scrubber in which the effluent gas is brought into contact with an absorption liquid containing water for removing further pollutants from the effluent gas. The wet scrubber is positioned at a point vertically higher than that of the dust removal device.

摘要： A raw gas collection system for collecting raw gas from a plurality of aluminium smelting pots is equipped with a plurality of branch ducts, each of which is arranged to channel a respective branch flow of raw gas from an aluminium smelting pot to a collection duct, which is common to and shared by the branch ducts. Each of said branch ducts is, near an outlet thereof, equipped with a curved section for aligning the branch flow with a flow direction of raw gas already present in the common collection duct, and a constriction for accelerating the branch flow through the branch duct outlet into the common collection duct. Furthermore, each of said branch ducts is equipped with a heat exchanger for removing heat from the respective branch flow of raw gas. The combined flow resistance of the constriction and the heat exchanger reduces the need for adjusting the respective branch flows using dampers, thereby reducing the power required to transport the raw gas.

摘要： An aluminum production electrolytic cell (14) comprises a bath (20) with bath contents (18), at least one cathode electrode (22) in contact with said contents (18), at least one anode electrode (16) in contact with said contents (18), and a hood (36), defining interior area (36a), covering at least a portion of said bath (20). The electrolytic cell (14) is equipped for effluent gases to be drawn from said interior area (36a). The electrolytic cell (14) also comprises at least one heat exchanger (74) for cooling at least a portion of the gases drawn from interior area (36a), prior to circulation thereof to interior area (36a) through at least one distribution device (90).
