A method of separating the oil with impurities from the crude oil by first placing oil with impurities into a cracking furnace and heating such to approximately 400-700.degree.C wherein there remains the pressure value of 3 kgf/cm2 insid e the cracking furnace such that the crude oil contained within oil with impurities is cracked into a gas. Next, the oil gas is cooled such that the oil gas after being cooled forms gas and the light crude oil. The gas is then guided into the gas manager and the lig ht crude oil into the crude oil manager for the use as the chemical intermediate or to be distillated into gas oil, diesel oil or fuel oil. Furthermore, plastic material can be added into the cracking furnace to high temperature cracking with the oil containing impurities as the fuel of indirect heating the cracking furnace to increase the yield of t he light crude oil.
