摘要
Abstract
The ammonium sulfate crystallization process faces issues such as multiple influencing factors,low crystallization rates,unstable nucle-ation,and poor ammonium sulfate quality.To optimize the kinetic conditions of the pre-scrubber in the desulfurization system of Kunming Iron and Steel's new facility,and to enhance ammonium sulfate crystallization yield,increase average crystal size,and improve uniform dispersion,this study takes the ammonium sulfate mother liquor from the pre-scrubber as the research subject.Stirring experiments were conducted at speeds of 0,200,250,300 r/min to investigate the appropriate stirring speed and its effects on crystallization yield and average particle size.The results in-dicate that under a stirring speed of 300 r/min,the maximum crystallization yield reached 67.26 g,the average particle size was relatively larger at 0.367 mm,and the purity of ammonium sulfate remained unaffected for 400 mL of ammonium sulfate mother liguor.The findings of this study can provide theoretical insights for optimizing the kinetic conditions of ammonium sulfate mother liquor crystallization.关键词
