Abstract: THIS INVENTION IS DIRECTED TO INCREASING THE CURRENT EFFICIENCY OF THE CATION EXCHANGE MEMBRANE LOCATED NEXT TO THE CATHODE IN A THREE CHAMBER CELL FOR THE ELECTROLYTIC CONVERSION OF AN ALKALI METAL SULFATE FOR USE IN THE REMOVAL AND RECOVERY OF SULFUR DIOXIDE CONTAMINANTS FROM FLUE GASES. AFTER THE REMOVAL OF SAID SULFUR DIOXIDE CONTAMINANT FROM FLUE GAS, CARBON DIOXIDE IS INTRODUCED INTO THE CELL''S CATHOLYTE SOLUTION BY CONTACTING CATHOLYTE SOLUTION WITH AT LEAST A PORTION OF THE SAID TREATED FLUE GAS AT ANY POINT IN THE CATHOLYTE SYSTEM, PREFERABLY BY RECYCLING THE CATHOLYTE SOLUTION BETWEEN THE CELL''S CATHODE COMPARTMENT AND A CARBONATION TOWER.

Abstract: THIS INVENTION RELATES TO A FOUR COMPARTMENT ELECTROLYTIC CELL FOR CONVERTING A SALT SOLUTION FEED INTO ITS CORRESPONDING ACID, ACID SALT AND CAUSTIC SOLUTION FOR USE IN CONNECTION WITH A LIQUID SO2 ABSORPTION SYSTEM. THE CAUSTIC PRODUCED ABSORBS THE SO2 GAS AND ON EXHAUSTION IS NEUTRALIZED WITH THE ACID SALT TO REFORM THE ORIGINAL SALT FEED SOLUTION. THE DESORBED SO2 GAS IS COLLECTED AND THE SALT SOLUTION RECYCLED AS FEED TO THE CELL. THE ACID PRO-

DUCED IN THE ANODE COMPARTMENT OF THE CELL IS REMOVED FROM THE SCRUBBER IN AN AMOUNT WHICH IS SUFFICIENT TO MAINTAIN THE REFORMED SALT FEED SOLUTION SUBSTANTIALLY NEUTRAL IN PH.
