Title:
ELECTRODIALYTIC METHOD AND APPARATUS THEREFOR
Document Type and Number:
Japanese Patent JP2002079255
Kind Code:
A
Abstract:
To enhance the separation and recovery effect of HCl to obtain high purity HCl in electrodialysis using a proton permselective cation exchange membrane.
HCl gas in an acidic gas component contained in exhaust gas is once absorbed by a washing liquid and HCl is separated and recovered from the washing liquid after the absorption of the HCl gas by electrolysis using the proton permselective cation exchange membrane C1 and an anion exchange membrane A. In this case, a plurality of the proton permselective cation exchange membranes C1 are inserted in the gap between the anion exchange membranes A mutually forming a pair.
