摘要： A raw gas collection system (15) for collecting raw gas from a plurality of aluminum smelting pots (4) is equipped with a plurality of branch ducts (16, 16a-d). Each branch duct (16, 16a-d) is arranged to channel a respective branch flow (32, 32a-b) of raw gas from an aluminum smelting pot (4) to a collecting duct (20a), which is common to and shared by branch ducts (16, 16a-d). Several of the branch ducts (16, 16a-d) are equipped with a combined heat transfer and flow resistance generating element (17) to remove heat from the respective branch flow (32, 32a-b) of raw gas and to balance the flow of raw gas in the raw gas collecting system (15). The combined heat transfer and flow resistance generating elements (17) reduce the need for adjusting the respective branch duct (16, 16a-d) flow volumes using dampers, thereby reducing the power required to transport the raw gas through the system.

摘要： An improved flue gas cooler 10, or bank of coolers 10, handles flue gas G from aluminum reduction cells in an aluminum smelter plant. Each flue gas cooler 10 has a gas inlet chamber 14, a gas outlet chamber 16, and a matrix of gas cooling tubes 18 extending between the inlet chamber and the outlet chamber. Each cooling tube 18 has a bell-shaped inlet end 19 comprising an aerodynamically curved gas-accelerating profile effective to facilitate streamlined flow of flue gas G into the tube. The improved flue gas cooler makes it possible to connect the flue gas cooler to receive flue gas G direct from the aluminum reduction cells without getting clogged by dust and sublimates present in the flue gas.

摘要： A raw gas collection system for collecting raw gas from a plurality of aluminum smelting pots is equipped with a plurality of branch ducts (28d), each of which is arranged to channel a respective branch flow (38d) of raw gas from an aluminum smelting pot to a collection duct (26A), which is common to and shared by the branch ducts (28d). Each of said branch ducts (28d) is, near an outlet (52d) thereof, equipped with a curved section (50d) for aligning the branch flow (38d) with a flow direction of raw gas (27A) already present in the common collection duct (26A), and a constriction (54d) for accelerating the branch flow (38d) through the branch duct outlet (52d) into the common collection duct (26A). Furthermore, each of said branch ducts (28d) is equipped with a heat exchanger (40d) for removing heat from the respective branch flow (38d) of raw gas. The combined flow resistance of the constriction (54d) and the heat exchanger (40d) reduces the need for adjusting the respective branch flows (28d) using dampers, thereby reducing the power required to transport the raw gas.

摘要： The treatment, through a dry adsorption process, of a gas from a hot electrolytic process for aluminum production comprises at least two stages. Particulate aluminum oxide (the adsorbent) passes through the stages of the adsorption process countercurrently to the gas. Thus, the gas is treated with a partly spent adsorbent in a first dry adsorption stage, whereupon the particulate adsorbent is separated from the gas downstream from the first adsorption stage. Part of the separated particulate adsorbent is removed from the adsorption process for recycling adsorbed fluorine-containing substances to the electrolytic process. The remainder of the separated adsorbent is recirculated in the first adsorption stage in order to optimize the adsorption of fluorine-containing substances and the desorption of sulfur dioxide from the aluminum oxide in this stage. Simultaneously, the gas is transferred to a second dry adsorption stage. In this second stage, the gas is treated with essentially unspent, reactive particulate aluminum oxide, so that any gaseous fluoride remaining in the gas is very efficiently adsorbed, while at the same time a substantial part of the sulfur dioxide in the gas is also adsorbed. Finally, this particulate aluminum oxide is separated from the gas downstream from the second dry adsorption stage, before the gas is discharged into the surrounding atmosphere. The separated aluminum oxide is transferred to the first adsorption stage, optionally after passing a desorption stage for the removal of the adsorbed sulfur dioxide in order to reduce the discharges of sulfur dioxide from the aluminum production. The separation of sulphur dioxide in the second adsorption stage is improved by recycling, to the second adsorption stage, aluminum oxide having undergone the desorption treatment.
