Preparation method of high-purity chlorine

The invention relates to the field of fine chemical engineering, specifically to a preparation method of high-purity chlorine. The method comprises the purification steps of preliminary dehydration, adsorption, light component removal, deep separation and the like. Compared with the prior art, the preparation method of the high-purity chlorine gas has the advantages that a deep separation type gaspurifier is additionally arranged; and test results show that the moisture of the prepared high-purity chlorine gas can be reduced to 100 ppb or below, and gas impurities can be reduced to 50 ppb orbelow. Compared with previous separated gas filter technologies, the preparation method has the following advantages: scaling-up is performed, a flow rate can reach 400 standard liters/minute to the maximum extent, and production efficiency is greatly improved. 本发明涉及精细化工领域，具体关于一种高纯氯气的制备方法；包含初步脱水，吸附，脱轻和深度分离等提纯步骤；本发明的一种高纯氯气的制备方法现有技术相比，增加了一种深度分离式气体纯化器，经测试，所制备的高纯氯的水分能够减少至100ppb及以下，气体杂质能减少至50ppb及以下；而且本发明的较之前的分离式气体过滤器技术，进行了工艺放大，
