| Abstract: | The process of double decomposition three step circulation for potassium nitrate production was introduced.Compared with the four step process,feeding steps in the new process were reduced and the crystallization rate of potassium nitrate was increased by over 20% after adding assistants into the reaction solution.Tests show that the mass fraction was 43 01%-45 68% for K 2O,13 80%-14 20% for N,0 3%-2 15% for Cl and 1 98%-3 45% for H 2O. |
