Embodiment
[0044] In an embodiment of the present invention, a system for producing high-purity hydrogen chloride is used, comprising: a reactor 10 for reacting purified high-purity hydrogen with purified high-purity chlorine; A compressor 20 for hydrogen chloride gas; a cooler 21 for hydrogen chloride passing through the compressor; a hydrochloric acid storage tank 60 for dissolving hydrogen chloride passing through the compressor in deionized water to prepare high-purity hydrochloric acid and storing the prepared hydrochloric acid ; a two-stage distillation column (ie, a first distillation column 40 and a second distillation column 50 ) for fractionating hydrogen chloride liquefied in a compressor to remove unreacted hydrogen and the like; and for storage in the distillation column Hydrogen chloride storage tank 30 for purified hydrogen chloride. Using this hydrogen chloride production system, hydrogen chloride is produced. Specifically, hydrogen and chlorine are respectively about 80...
