  • Electrolysis process for removal of caustic in hemicellulose caustic
    Patent number: 5589053
    Abstract: Pulping chemicals and hemicellulose are recovered from a starting solution essentially free of lignin but containing a mixture of hemicellulose and caustic by electrolyzing this solution in the anolyte compartment of an electrolytic cell. By electrolysis, the concentration of caustic in the anolyte is decreased and the concentration of caustic in a catholyte of said cell is increased so as to allow recovery, of about 60 to about 80 percent of the caustic contained in the hemicellulose caustic starting solution.
