Method and apparatus for concentrating chlorine gas.

摘要

A method and an apparatus for concentrating/purifying a chlorine gas are here disclosed in which a pressure swing adsorption method for alternately repeating an adsorbing operation and a desorbing operation is applied to the concentration/purification of the chlorine gas and novel improvements are added thereto. According to the present invention, one or more adsorbing towers packed with an adsorbent for adsorbing the chlorine gas are used to obtain a high-purity concentrated/purified chlorine gas and a treated exhaust gas scarcely containing the chlorine gas from the chlorine gas containing impurities.
