PURPOSE: A method for stripping oils using nitrogen gas is provided to easily adjust a flash point, to directly mix oil, which is separated from an intermediate stage, with kerosene products and diesel products, and to obtain economical effects without additional facilities excluding an assisting separator. CONSTITUTION: A stripping method of oil includes a step of separating HCN and LCO, having a boiling point 180°C - 360°C, from a main separation column(100) and a step of eliminating light distillate and moisture using nitrogen gas before being mixed with diesel products. The pressure of injected nitrogen is more than the pressures of the main separation column and an assisting separation column.
