对硝酸铵和氯化钾复分解生产硝酸钾的生产中的配料过程及其影响因素,以K~+,NH_4~+‖Cl~-,NO_3~-—H_2O四元水盐体系相图为依据作了理论分析,指出以相图理论为基础,利用物料衡算的方法确定各配盐量来指导操作是非常必要的。 The process of the compounding and its influencing factors in the production of potassium nitrate by metathesis of ammonium nitrate and potassium chloride are based on the phase diagram of quaternary water and salt system of K ~ +, NH_4 ~ + Cl ~, NO_3 ~ - H2O The theoretical analysis shows that it is very necessary to use the method of material balance calculation to determine the amount of salt to guide the operation based on phase diagram theory.
