Heavy crude oil of Tahe is a inferior and heavy oil. It is processed with the shallow splitting unit and cannot get qualified with light oil, but can get qualified with heavy fuel oil.
The new technology is suitable for vacuum residue of dense crude oil. The breaking depth can be increased. As the unit has passed a long term practice, it can be a reference for similar units.
