| Abstract: |
| Based on the e-p method and material flows method presented in analyzing the overall energy intensity of alumina,the formulas used to quantitatively calculate the effect of change of process in alumina refinery with Bayer-sinter combined method on its energy intensity were presented.The process adjustment includes different proportion of Bayer and sinter method,different ratio of purified sinter liquor output to carbon dioxide precipitation to seed precipitation,and different proportion of direct and indire... |
