METHOD OF GASOLINE PRODUCTION Russian patent published in 2001 - IPC

FIELD: oil-refining industry; applicable directly at oil fields. SUBSTANCE: method consists in mixing of gasoline fractions which are used in the form of product of hydrocyclonation of oil preliminarily heated up to 60-90 C in step hydrocyclone, separation of vapor-gas mixture in center of flow rotation and its subsequent condensation at temperature of 15-25 C, or gas condensate separated in transportation and cooling of gas in the amount of 70-95 vol. % with oxygen-containing additive in the form of mixture in amount of 2-10 vol.% of methylal-methanol fraction of isoprene production by dioxane method, with overhead fraction of alcohol production, the balance, or mixture in amount of 3-15% of still residue of production of butyl alcohols and methylal-methanol fraction of isoprene production by dioxane method, the balance. EFFECT: intensified process of gasoline production from low-cost wastes of petrochemical production. 1 dwg, 1 tbl
