Quality specifications for redistedilled asphalt oil
Thread Content
Is there any expert who can provide the parameter specifications for the re-deasphalted oil from solvent deasphalting units?
The key is to determine what the deasphalted oil is intended for. If it is to be used as a feedstock for catalysis, we previously required that the residue content not exceed 9 (this value is flexible and can be adjusted depending on the properties of the catalytic feedstock and the proportion of deasphalted oil in it).
If re-deasphalted oil is fed into wax oil hydrocracking, the asphaltene content should be less than 500 ppm, and the blending ratio must also be controlled.
