ABSTRACT:
The present invention comprises an improved electrodialytic cell and closed loop process for removing SO.sub.2 from SO.sub.2 containing gases. An aqueous scrubbing medium is used to remove the SO.sub.2 from the gas. A two compartment electrodialytic water splitter and a means for stripping is used to isolate the SO.sub.2 and regenerate the aqueous scrubbing medium. Use of univalent cation selective membranes, recycling of the acid product to the base loop of the water splitter, and a prescrubber allow high concentrations of scrubbing solution to be treated without significant fouling inside the membranes. The above process embodiments may be used either alone or in combination.
