Abstract:
An integrated hydrocracking, vacuum distillation and solvent deasphalting process that provides for controlling the amount of polycyclic aromatic hydrocarbons in a heavy oil recycle stream by separating a portion of the heavy oil recycle stream into various fractions in a vacuum distillation unit, and processing the various fractions in a manner, including solvent deasphalting, that allows for the control of the polycyclic aromatic hydrocarbons in the heavy oil recycle stream.
