Title: HYDROCRACKING PROCESS AND APPARATUS WITH HEAVY POLYNUCLEAR AROMATICS REMOVAL
Abstract:
One exemplary embodiment can be a process for treating a hydrocracking fraction. The process can include obtaining a bottom stream from a fractionation column, stripping HPNAs from the bottoms stream and adsorbing HPNAs from the stripped stream to provide an adsorbed stream that can meet a desired HPNA concentration specification. The adsorption step can be adjusted to achieve an adjusted HPNA concentration.
