Abstract
Studies of an electromembrane process for regenerating acid from spent sulfuric acid pickle liquor have indicated that the process is technically feasible. The studies have shown that the iron ions in spent pickle liquor can be removed and replaced by hydrogen ions to regenerate H2SO4 in electromembrane cells. A method of removing iron from spent liquor that involves the formation of insoluble iron hydroxides is preferrable to plating iron metal onto cathodes. Estimated treatment costs were $0.045 plus or minus 0.002 per gallon, whereas the combined costs of purchasing acid and disposing of spent liquor by existing methods were in the range of $0.015 to $0.06 per gallon of spent liquor. A determination of the long-term performance of the ion-exchange membranes when treating actual pickle liquors that contain organic pickling aids is needed. (Author)
