Optimization of Sodium Sulfite Production on the Basis of Graphical Analysis of Solubility Diagrams for Systems Na+, NH4+//Cl-, SO32--H2O and Na+, NH4+//Cl-, HSO3--H2O

Optimization of Sodium Sulfite Production on the Basis of Graphical Analysis of Solubility... The solubility was studied in the systems Na2SO3-NaCl-NH4Cl-(NH4)2SO3-H2O at 20 and 40°C and NH4HSO3-NaHSO3-NaCl-NH4Cl-H2O at 40°C by the graphic-analytical method. The obtained results were used to choose the most efficient method for obtaining sodium sulfite by conversion and to substantiate the optimal temperature condition of the process. The data obtained in studying stages of conversion of ammonium sulfate solution with sodium chloride and crystallization of a by-product-ammonium chloride, made it possible to find the optimal technology of the closed cyclic process. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Applied Chemistry Springer Journals
