摘要： The present invention provides a method for producing high-purity hydrogen chloride, comprising the steps of: purifying each of crude hydrogen and crude chlorine as raw materials to a purity of 99.999% or higher; reacting an excessive molar amount of the purified hydrogen with the purified chlorine at a temperature ranging from 1,200 °C to 1,400 °C to synthesize hydrogen chloride; converting the hydrogen chloride to a liquid state by compression; and purifying the hydrogen chloride and separating unreacted hydrogen by fractional distillation. The invention also provides a system for carrying out the method. According to the method and system, an environmentally friendly production process can be provided, which can easily produce a large amount of hydrogen chloride having a purity of 3 N (99.9%)-6 N (99.9999%) in a cost-effective manner and enables energy consumption to be significantly reduced.
摘要翻译：本发明提供高纯度氯化氢的制造方法，其特征在于，以粗纯氢和粗氯为原料纯化纯度为99.999％以上的步骤。在1200℃至1400℃的温度范围内使纯化氢与纯化氯反应过量，合成氯化氢; 通过压缩将氯化氢转化为液态; 并通过分馏纯化氯化氢和分离未反应的氢。本发明还提供了一种用于执行该方法的系统。根据该方法和系统，可以提供一种环保生产方法，其可以以成本有效的方式容易地产生纯度为3N（99.9％）-6N（99.9999％）的大量氯化氢，能够显着降低能耗。
