| Abstract: | Now main method for making potassium nitrate in China is the process for making potassium nitrate and ammonium chloride by complex decomposition cycle method of ammonium nitrate and potassium chloride.It indicates that Problems of lower potassium nitrate crystallization rate,bad cooling crystallization effect,serious fouling of ammonium chloride,high steam energy consume and improper selection of centrifuger etc.exist in this production technology,the reason causing the problems was analyzed,the appropriate improvement measure and reasonable suggestion were suggested. |
