METHOD AND APPARATUS FOR ANALYSIS OF CHEMICAL CONSTITUENTS IN AN ELECTROLYSIS CELL |
摘要 |
The present invention relates to a method and an apparatus for the analysis of chemical constituents in an electrolysis cell for production of metal. In particular, the invention relates to continuous analysis of the alumina (oxide) concentration and the cryolite ratio in aluminium producing cells working in accordance with the Hall-Héroult process. The invention involves the use of light spectroscopy such as Raman spectroscopy for the analyses of light emitted from the cell and the light is represented as a spectrum. The analysis is performed directly in the cell while the cell is in its producti on mode.
