ABSTRACT:
A process for separation and removal of stable polycyclic aromatic dimer foulants from refinery process streams by blending a paraffinic stream with a portion of heavy effluent from a hydrocracking reactor to induce precipitation of foulant, which may then be separated and removed from the hydrocracker. Additional embodiments include introduction of flocculating agents and adjusting the temperature of the blend.
