The present invention provides a method for operating a stripper that is provided for a separating process in an aromatic component processing apparatus in which the stripper separates a component that is lighter than an aromatic component from the aromatic component via a distillation operation. In the method, using a HIDiC as the stripper, the pressure of the column top of rectifying section (201) of the HIDiC is determined, and the pressure of the column top of stripping section (202) of the HIDiC is set to be lower than the pressure of the column top of rectifying section (201).
