摘要
实验研究了氨作为硫酸钾结晶助剂 ,在常温常压下石膏和氯化钾在水盐相体系中有选择地结晶硫酸钾的原理及工艺流程。该流程具有节省热能 ,操作维护容易 ,效率高等优点。
The researches introduced potassium sulfate crystallized with ammonia as an assistant agent and the principle and process of gypsum and potassium chloride reacted selectively to produce potassium sulfate in the phase of water and salt under normal temperature. This process has advantages of thermal energy saving, easy operation and high efficiency.
