PURPOSE: A method for the separate purification of similar gasoline is provided to recycle mass similar gasoline by properly separately purifying the similar gasoline. CONSTITUTION: Water is doubly mixed with similar gasoline in a stir tub (11) based on the whole volume of the similar gasoline. A foreign substance is removed from a mixture of the similar gasoline by a cyclone (12). The mixture is stirred in a heating stir tub (1). The similar gasoline mixed with water is transferred to a waste fluid storage (20) through a first discharge path (2) to generate layer separation. Layer-separated waste fluid is transferred to a first column still (60) through a waste fluid supply line (3). A soluble substance is separately purified by heating the separated waste fluid in a second column still (30). An insoluble substance is distilled in the second column still to separate solvent from toluene. |
