Abstract
PURPOSE: To remove scale efficiently in simple operation by subjecting the scale adhered to a machinery and an arranged pipe treating steam generated from a black liquor from which a pulp is removed to heating treatment by using an akaline aqueous solution.
CONSTITUTION: When steam generated from a digesting liquor of a lignocellulose substance containing anthraquinone or a steam distillatable anthraquinone compound or steam generated from a black liquor obtained by removing a pulp from the digesting liquor is treated, scale is adhered to a machine and an arranged pipe of a system thereof. A aqueous sodium hydroxide solution with a predetermined concn. is entered in a service tank and, after heated to 60W100°C, filled in the machine and the arranged pipe of a scale adhered side in a definite amount by a pump and the aqueous sodium hydroxide solution is recirculated between the service tank and the machine by using the pump.
