Extraction of Aromatic Hydrocarbons from Gasoline Fraction by Blended Extractants
Extraction of aromatic hydrocarbons from the 62-180 A degrees C gasoline fraction of Astrakhan gas condensate is studied for the preparation of pyrolysis feedstock. Comparative analysis of the extraction capacity of triethylene glycol, N-methylpyrrolidone, and blended extractants showed that a blended extractant containing 40-50 wt. % polyethylene glycol, 45-55 % N-methylpyrrolidone, and 5 % water is most effective in extracting aromatic hydrocarbons.
