摘要
A method for the regeneration of pulping or bleaching chemicals from spent liquor containing salts of polybasic organic acids. The liquor is evaporated and then burned so that organic matter will be discharged as carbon dioxide and water, and a carbonate residue is formed. Carbon dioxide is expelled from the carbonate with an acid by autocaustization to regenerate the cooking chemicals.
