Abstract
En elektrolysecelle der det produseres metaller må tilsettes en nøyaktig mengde råstoff (som alumina), og som en virkning av reaksjonen som skjer i cellen, må man trekke ut produktet (som aluminium) og fjerne eventuelle avfallsprodukter (som HF og C02). For å avkjøle cellen hensiktsmessig og sikre oppsamling av alle avgassene fra cellen, som ikke er gasstett, suges det normalt inn omtrent 100-150 ganger mer luft fra omgivelsene enn gassvolumet som produseres av cellen. Den foreliggende oppfinnelsen dreier seg om prinsippene om hvordan man kan utforme en innretning der man kan kombinere tilførsel av råstoffet alumina til cellen og samtidig trekke ut mer C02-konsentrerte avgasser fra cellen enn det som er standard fremgangsmåte i aluminiumsindustrien i dag. De tre totalvirkningene man får med hensyn til avgassene er. 1. Det tas ut et mindre totalvolum av gass fra cellen, med mulighet for å redusere den totale størrelsen på gassvaskerne. 2. Som følge av punkt l vil den oppsamlede prosessgassen få høyere temperatur enn før og er derfor mer egnet for varmeutvinning. 3. Hvis det suges inn mindre «falsk luft» til gassoppsamlingskamrene, øker konsentrasjonen av C02 i avgassene vesentlig, slik at det blir mulig å oppfange og skille ut C02 med standard teknologi som brukes til å fange opp C02 fra prosesser så som kraftanlegg.An electrolytic cell in which metals are produced must be added to the exact amount of raw material (such as alumina) and as a result of the reaction that takes place in the cell, the product (like aluminum) must be extracted and any waste products (such as HF and CO 2) removed. To cool the cell appropriately and ensure the collection of all the exhaust gases from the cell, which is not gas-tight, normally about 100-150 times more ambient air is sucked in than the volume of gas produced by the cell. The present invention revolves around the principles of how to design a device whereby the feedstock alumina can be combined to the cell and at the same time extract more CO 2 concentrated exhaust gases from the cell than is the standard process in the aluminum industry today. The three total effects of the exhaust are. 1. A smaller total volume of gas is withdrawn from the cell, with the possibility of reducing the total size of the gas washers. 2. As a result of point 1, the collected process gas will have a higher temperature than before and is therefore more suitable for heat recovery. 3. If less "false air" is sucked into the gas collection chambers, the concentration of CO 2 in the exhaust gases increases substantially, enabling the capture and separation of CO 2 with standard technology used to capture CO 2 from processes such as power plants.
