| Abstract: | The principal factors which influence the precipitation of sodium carbonate,sodium sulfate and sodium silicate during the evaporation process of Bayer spent liquor were studied in experimental research.The precipitation principals of the three salts were investigated under different evaporation conditions.The results provided a theoretic proof on releasing the scaling on the heat exchange tube wall and reducing energy consumption. |
