摘要
介绍了一种氯化氢精制技术。将曼海姆法硫酸钾联产的氯化氢气体经过洗涤、吸收、解吸、干燥等工艺进行精制提纯,获得纯度大于99.9%(质量分数)的氯化氢气体。提出了精制后高纯氯化氢气体的应用方向。阐述了该工艺对促进相关行业发展的重要性。
The method of purifying hydrogen chloride is introduced.The hydrogen chloride produced in the production of potassium sulfate by MannHeim process is purified through washing,absorption,desorption and drying sections.The purity of hydrogen chloride obtained is up to 99.9%.The orientation of application of high purity hydrogen chloride is presented,and also the significance of this process for promoting the development of industries concerned is described.
