TiCl_4熔盐氯化过程通氯管道堵塞原因及对策分析

Analysis on Causes of and Countermeasures for Blockage of Chlorine Feeding Pipe in the Process of Molten Salt Chlorination

对TiCl4熔盐氯化过程通氯管堵塞的原因进行了分析,发现熔盐氯化温度、原料、压力、熔盐体系与操作情况是造成通氯管堵塞的主要因素;生产过程可以通过控制温度、压力、熔盐体系、操作参数,合理选择原料与优化设计来减少或避免通氯管堵塞问题的发生。

The causes of the blockage of chlorine pipe in the process of molten salt chlorination for TiCl4 pro- duction are analyzed in this paper . It has been found that the main factors leading to blockage of chlorine pipe are temperature, raw materials, pressure, molten salt and operation. Some measures can be taken to re- duce or avoid the occurrence of blockage, including appropriate control of temperature, pressure, molten salt and operating parameters, reasonable choice of raw materials and optimization of desire scheme.
