  • Cleaning method of oil tank and cleaning device of same
    Patent number: 10130978
    Abstract: Crude oil is discharged from an oil tank. A nozzle is inserted into a support opening formed in advance on a roof of the oil tank. A cleaning liquid containing LCO is injected from the nozzle over the sludge accumulated inside the oil tank after the crude oil is discharged from the oil tank. The cleaning liquid in which the sludge is dissolved is discharged from the oil tank and is returned to the oil tank for recycle cleaning. Subsequently, the cleaning liquid in which the sludge is dissolved is discharged from the oil tank.
