Abstract: The low flash point of Tahe vacuum residue affects its derivative asphalt product quality. Thus improving the Tahe vacuum residue flash point is beneficial to the asphalt product quality and to the capacity of the plant. Based on the analysis and comparison of Tahe crude with Kuwait crude, a conclusion could be drawn that the reason for low flash point of Tahe vacuum residue is due to high content of asphaltene in the crude. By blending FCC slurry in atmospheric residue and intensifying vacuum distillation, the Tahe vacuum residue flash point can be significantly improved. Blending 1% FCC slurry make the vacuum residue flash point increase by 1.6 ℃. A high quality road asphalt product can be manufactured using such residue with SBR.
