Anhydrous Sodium Sulfate Crystallization Process Of The Large Particles, And Mathematical Models

This paper review the preparation theory of anhydrous sodium sulfate and the method of made it, and found the crystal model of anhydrous sodium sulfate based on experiment date. The mechanism of made it by vacuum evaporation using DTB crystallizer is studied, and the detail of the technical flow is discussed. The factors which influence the granularity of anhydrous sodium sulfate are studied .Under certain experiment condition. the anhydrous sodium sulfate which granularity is 0.4-0.5 it m was made . The model crystal kinetic parameters was determined by batch transient method. The Laplace transform of population balance equation with respect to size was used in this method. The crystal model of anhydrous sodium sulfate is founded.
