Fractionation of reformate: A new variant of gasoline production technology
- and others
The Novo-Ufa Petroleum Refinery is the largest domestic producer of the unique high-octane unleaded automotive gasolines AI-93 and AI-95 and the aviation gasolines B-91/115 and B-92. The base component for these gasolines is obtained by catalytic reforming of wide-cut naphtha; this basic component is usually blended with certain other components that are expensive and in short supply: toluene, xylenes, and alkylate. For example, the unleaded gasoline AI-93 has been prepared by blending reformate, alkylate, and toluene in a 65:20:15 weight ratio; AI-95 gasoline by blending alkylate and xylenes in an 80:20 weight ratio; and B-91/115 gasoline by compounding a reformate obtained with light straight-run feed, plus alkylate and toluene, in a 55:35:10 weight ratio. Toluene and xylenes have been obtained by process schemes that include the following consecutive processes: redistillation of straight-run naphtha cuts to segregate the required narrow fraction; catalytic reforming (Platforming) of the narrow toluene-xylene straight-run fraction; azeotropic distillation of the reformate to recover toluene and xylenes. A new technology based on the use of reformate fractions is proposed.
