6 Using a vacuum during the smelting and refining of alloys removes dissolved gasses, as well as impurities with high vapour pressure. When smelting is carried out in vacuum induction furnaces, the intensification of the discussed processes is achieved by intensive mixing of the bath, as well as an enhanced mass exchange surface (liquid metal surface) due to the formation of a meniscus. This is ...

Aluminium production data are necessary to estimate PFC emissions from aluminium smelting regardless of the estimation method chosen. Countries should obtain smelter-level data on an annual basis, so that they can use smelter-specific emission factors. At a plant-level, actual production data should be obtained directly from producers. Since
