| Abstract: | The high silicon content in green liquor of straw pulping affects the progress of alkali recovery,it is also disadvantageous to the recycling of lime mud.The effects of silicon removal with pre-causticization and carbon dioxide were studied in this paper.The results show that the silicon removal rate can be up to 60%~80% for pre-causticization and can be up to 90% for CO_2. |
