锆、铪分离工艺包括:将锆、铪氯化物同一种主要是氯化锂的熔盐溶剂及钠、钾、镁、钙中的至少一种氯化物混合,将此混合物输送到一蒸馏柱中,反应后的氯化铪从蒸馏柱顶部星蒸汽而除去,其中一部分蒸汽被蒸汽压缩机压缩,并输送到逆流冷凝器的溶剂中;氯化锆作为一种与从蒸馏柱底部来的碱一碱土金属氯化物生成的液态复盐而除去;用电化学还原分离出锆,并从回流于逆流冷凝器的 The zirconium and hafnium separation process comprises mixing zirconium and hafnium chloride with a molten salt solvent, predominantly lithium chloride, and at least one chloride of sodium, potassium, magnesium, and calcium and passing the mixture to a distillation column The reacted hafnium chloride is removed from the star vapor at the top of the distillation column and a portion of the vapor is compressed by the vapor compressor and sent to the solvent in the countercurrent condenser. Alkaline earth metal chloride generated by the liquid double salt and removed; electrochemically reduced zirconium separation, and from the reflux to the countercurrent condenser
