  • Phenol tar desalting method
    Patent number: 5962751
    Abstract: A tar desalting process wherein the tar containing salts is mixed with dilute aqueous orthophosphoric acid in either a batch or continuous process, allowed to settle into two phases, an organic phase and an aqueous phase containing most of the salts which is then removed from the organic phase. The process removes a high percentage of the salts from the tar and reduces fouling and corrosion of downstream equipment.
