Solvent deasphalting of blended slurry – desulfurization rate
Thread Content
I would like to ask: when using vacuum residue mixed with catalytic cracking slurry as the feedstock and passing it through a solvent deasphalting unit, what is the relationship between the yield of deasphalted oil and its sulfur content, compared to the relationship obtained when using only vacuum residue as the feedstock for the solvent deasphalting unit?
To add some clarification: I would like to ask everyone what impact the two operating conditions – using a mixture of vacuum residue and catalytic cracking slurry as feedstock, versus using only vacuum residue – have on the sulfur content in the deasphalted oil produced by the solvent deasphalting unit :)
Generally speaking, the impact is minimal; since the slurry is lighter, the amount of dissolution will increase, while the sulfur content is likely to remain unchanged. The proportion of the slurry itself should also be small.
