Producing gasoline and/or co-production of aromatic bases, useful for petrochemicals, comprises e.g. producing cut extract and raffinate, sending raffinate in catalytic reforming unit and sending extract in aromatic complex unit

摘要

Producing gasoline, and/or co-production of aromatic bases from one or more naphtha cuts, in which a charge (1) is sent to aromatic separation unit, comprises: producing cut extract (3), and a cut raffinate (2); sending the raffinate in catalytic reforming unit; producing gasoline cut having high octane index (4), where the gasoline is recycled towards the aromatic separation unit, or sent to aromatic complex unit by flow (6); sending all or part of the extract in aromatic complex unit to produce aromatic bases (7) and (8); and sending other part of the extract to gasoline pool. Process for producing gasoline having octane index of greater than 95, and/or co-production of aromatic bases from one or more naphtha cuts obtained from atmospheric distillation, fluid catalytic cracking (FCC), coking, steam cracking, hydrocracking, natural gas condensate fractionation, in which a charge (1) is sent to an aromatic separation unit, comprises: producing a cut extract (3) containing the majority of the aromatics, and a cut raffinate (2) containing the majority non-aromatic compounds; sending at least partly the raffinate in a catalytic reforming unit; producing a gasoline cut having high octane index (4) constituting a part of the gasoline pool, where the gasoline is wholly/partially recycled towards the aromatic separation unit, or wholly/partly sent to the aromatic complex unit by flow (6); sending all or part of the extract in an aromatic complex unit allowing to produce aromatic bases (7) and (8); and sending the other part of the extract to the gasoline pool.
