摘要

在324 ~ 424℃的温度范围内，采用不同类型的塔架，在中试装置上研究了KCl-AlCl3-ZrCl4熔体吸附ZrCl4蒸气的过程。在研究的温度和压力范围内，建立了ZrCl4平衡浓度与温度的关系。确定了达到平衡浓度所需的托盘数。对萃取ZrCl4和HfCl4精馏过程中回流冷凝器的操作方式提出了建议。

Absorption of Zirconium Tetrachloride by a KCl–AlCl3 Melt as Applied to the Extractive Distillation of Zirconium and Hafnium Tetrachlorides

The process of ZrCl₄ vapor absorption by a KCl–AlCl₃–ZrCl₄ melt is studied on a pilot setup within a temperature range of 324–424°C in columns of different types. The dependence of the equilibrium ZrCl₄ concentration on temperature is established within the studied range of temperatures and pressures. The number of trays required to attain the equilibrium concentration is determined. Some recommendations on the reflux condenser operation regimes in the process of extractive ZrCl₄ and HfCl₄ distillation are given.
