For refineries, what are the restrictions on crude oil in the residual oil hydrogenation catalytic raw material pretreatment-catalytic cracking process? Which crude oil is not suitable for residual oil hydrotreating?
For VRDS and ARDS, the main thing is to control the sulfur content not to be too high (about 3%), the metal content must be appropriate, it is estimated that it cannot be processed if it is greater than 200PPm, the nitrogen content is moderate (foreign nitrogen content is low, it should be no problem), and the other is the viscosity, the fluidity must be good. VR and AR cannot handle all residual oil. The properties of the residual oil are too poor and can only cause coking.
