Abstract: The solvent deasphalting unit of a certain company uses heavy oil slurry and deoiled asphalt blending method to produce road asphalt. After the change of feedstock quality in the unit, the production of No. 100 road asphalt often results in substandard products, which seriously affects the production of deoiled asphalt and heavy oil slurry, and is not conducive to the safe and stable operation of the unit. Based on the current production situation, this paper deeply analyzes the factors affecting the blending of No. 100 road asphalt, including the content of heavy oil slurry less than 350°C, the softening point of deoiled asphalt, and the blending ratio of heavy oil slurry and deoiled asphalt. A method for rapidly producing No. 100 road asphalt is proposed: on the basis of ensuring the quality and stable intake of deoiled asphalt, the "prefer heavier than lighter" principle is followed for the first blending; based on the penetration results of the first blending, the heavy oil slurry is added proportionally for the second blending. This method effectively improves the yield of No. 100 road asphalt and provides reference for similar units to produce No. 100 road asphalt by blending method.
