Abstract: Tahe crude is characterized by its high content in sulfur, acid value, conradson carbon residue, asphaltenes, metals and low yield of light distillates. Two combined processes for Tahe crude oil，atmospheric flashing-solvent deasphalting process and atmospheric distillation-delayed coking process were compared to see which one is better for more liquid yield. The results show that the total liquid yield can reach 78.77% by the atmospheric flashing-solvent deasphalting combined process, 9.47% more than the atmospheric distillation-delayed coking process (69.30%). The liquid distillations with high quality from the former process can be used as catalytic cracking or hydrotreating feeds. Meanwhile, the corrosion of petroleum acid existing in atmospheric and vacuum distillation can be retarded as the operating temperature of atmospheric flashing-solvent deasphalting combined process is far lower than the temperature where the corrosion of petroleum acid is seriously occurred. In aspect in increasing total liquid yield, improving liquid oil properties and retarding corrosion, the atmospheric flashing-solvent deasphalting combined process is superior to the compared process.
