氯化钾与硫酸钠制硫酸钾工艺的优化

摘要

根据K+，Na+∥Cl-,SO42-—H2O体系相图，提出了氯化钾与芒硝制备硫酸 钾工艺中新的工业化生产循环和解决钾芒硝富集问题的具体方案，取得良好效果。%Accordinh to the study and analysis on phase diagram of the Na+，K+∥Cl-， SO42--H2O system, new cycle for preparation of potassium sulfate by sodium sulfate and potassium chloride and treatment of surplus sodium sulfate.3p otassium sulfate (Na2SO4.3K2SO4) are presented, achieve good results.
