When manufacturing aluminium in primary smelters, air purification is required in many other areas in addition to aspiration and gas treatment in electrolytic cells. The ENTECCOgroup supplies air purification systems for:
Various smelting equipment is used to manufacture secondary aluminium.
Due to the air contamination that is typical for the relevant process, toxic and acidic harmful gases or hydrocarbon compounds must also be cleaned from the flue gas in addition to particulate dusts. The additive-fed entrained flow process is used for this. The process engineering that this requires has basic characteristics that remove these applications from a common dust removal system.
