• Definition

  Extracts (petroleum), heavy clarified oil solvent, condensed-ring-arom is a complex combination of hydrocarbons obtained as the extract from the solvent extraction of catalytic cracked clarified oil. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly higher than C25 and boiling above approximately 425.degree.C (798.degree.F). This stream is likely to contain 5 wt. % or more of 4- to 6-membered condensed ring aromatic hydrocarbons.
