Definition
Extracts (petroleum), light 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 in the range of C15 through C25 and boiling in the range of approximately 340.degree.C to 400.degree.C (644.degree.F to 752.degree.F). This stream is likely to contain 5 wt. % of 4- to 6-membered condensed ring aromatic hydrocarbons.
