Abstract

METHOD FOR REDUCING CORROSIVE IONS IN AROMATIC COMPOUND EXTRACTION SOLVENT In order to suppress corrosion of an extractor caused by corrosive ions contained in an aromatic compound extraction solvent of a circulation system, a method for reducing corrosive ions in an aromatic compound extraction solvent is provided, by which the corrosive ions in the aromatic compound extraction solvent are conveniently and efficiently reduced. A method for reducing corrosive ions in an aromatic compound extraction solvent in a circulation system where the aromatic compound extraction solvent circulates, the corrosive ions being at least one kind selected from the group consisting of chloride ions, sulfate ions, and sulfite ions, the method comprising: a step of forming a non-volatile salt by adding a corrosive ion scavenger to react the corrosive ions with the corrosive ion scavenger, and a step of removing the salt resulting from concentrating the solvent comprising the salt.
