Abstract
In a double-stream circuit the bauxite slurry is fed into a digester and is mixed with the reheated spent liquor. In contrast, in a single-stream circuit, the slurry is combined with the spent liquor and is then reheated and digested as it passes through the heat-exchangers. Although numerous studies have been carried out to understand the mechanisms of scale formation and to develop scale inhibition strategies in double-stream circuit Bayer plants, there is still insufficient relevant research on single-stream Bayer plants with their high solids density heat-exchanger environment. The aim of this study was therefore to improve understanding of scale formation processes, in particular the mechanisms and kinetics of sodium aluminosilicate scale formation, in single-stream Bayer process circuits and to provide theoretical support for development of scale inhibition strategies.
