Definitions
- the present invention relates generally to methods for isomerizing and reforming of hydrocarbons, and more particularly relates to methods for recovering hydrogen from isomerizing and reforming of hydrocarbons.
- a hydrocarbon feedstock of, for example, C 5 hydrocarbons to about Cii hydrocarbons is contacted with a reforming catalyst to convert at least a portion of the heavier hydrocarbons to aromatic hydrocarbons to increase the octane content of gasoline.
- the catalytic reforming of the heavier hydrocarbons also produces significant quantities of hydrogen, which has become very important to many refiners and can be used, for example, for hydrotreating to reduce sulfur levels in gasoline and other fuels.
- many refineries use catalytic reforming processes that have a re-contacting zone for sequestering hydrogen from the reforming zone effluent. Unfortunately, the quantities of hydrogen that are typically recovered in catalytic reforming processes are often insufficient to meet the hydrogen demands in many refineries.
- a light hydrocarbon fraction containing normal paraffins of, for example, butane, pentane, and/or hexane is contacted with an
- the isomerization product stream contains branched paraffins, such as iso-butane, branched pentane, and/or branched hexane that are used to increase the octane content of gasoline.
- the isomerization net gas stream contains hydrogen and light end hydrocarbons, e.g., Ci to C 5 and possibly some C 6 hydrocarbons. Unfortunately, many refineries burn the isomerization net gas stream as fuel gas because the equipment and operating cost associated with recovering hydrogen from this stream is prohibitively high despite their unmet need for hydrogen.
- a method for recovering hydrogen from isomerizing and reforming of hydrocarbons comprises combining a HCl-scrubbed, isomerization-zone net gas stream that comprises hydrogen and C 6 - hydrocarbons with a reforming-zone net gas stream that comprises hydrogen and C 6 - hydrocarbons to form a combined net gas stream that comprises hydrogen and light end hydrocarbons.
- the light end hydrocarbons are extracted from the combined net gas stream in a re-contacting zone using a reforming-zone product stream that comprises C 5 + hydrocarbons to form a hydrogen-rich net gas stream.
- a method for recovering hydrogen from isomerizing and reforming of hydrocarbons comprises contacting a paraffin feed stream with a chloride-promoted isomerization catalyst in the presence of hydrogen to form an isomerization reactor-zone effluent.
- the isomerization reactor-zone effluent is separated into an isomerization-zone product stream that comprises branched paraffins and a isomerization-zone net gas stream that comprises hydrogen, chloride-containing compounds including HC1, and C 6 - hydrocarbons.
- At least a portion of the chloride-containing compounds is removed from the isomerization-zone net gas stream to form an HCl-scrubbed, isomerization-zone net gas stream.
- Water is removed from the HCl-scrubbed, isomerization-zone net gas stream to form a water- depleted, HCl-scrubbed, isomerization-zone net gas stream.
- the water-depleted, HCl- scrubbed, isomerization-zone net gas stream is combined with a reforming-zone net gas stream that comprises hydrogen and C 6 - hydrocarbons to form a combined net gas stream that comprises hydrogen and light end hydrocarbons.
- the combined net gas stream is compressed with a compressor that is upstream from a re-contacting zone to form a compressed combined net gas stream.
- the compressed combined net gas stream and a reforming-zone product stream that comprises C5+ hydrocarbons including aromatics are advanced through the re-contacting zone.
- the light end hydrocarbons are extracted from the compressed combined net gas stream in the re-contacting zone using the reforming- zone product stream to form a hydrogen-rich net gas stream and an aromatics-containing product stream.
- a method for recovering hydrogen from isomerizing and reforming of hydrocarbons comprises contacting a paraffin feed stream with a chloride-promoted isomerization catalyst in the presence of hydrogen to form an isomerization reactor-zone effluent.
- the isomerization reactor-zone effluent is separated into an isomerization-zone product stream that comprises branched paraffins and a isomerization-zone net gas stream that comprises hydrogen, chloride-containing including HC1, and C 6 - hydrocarbons.
- At least a portion of the chloride-containing compounds is removed from the isomerization-zone net gas stream to form an HCl-scrubbed, isomerization-zone net gas stream.
- Water is removed from the HCl-scrubbed, isomerization-zone net gas stream to form a water-depleted, HCl-scrubbed, isomerization-zone net gas stream.
- the water-depleted, HCl-scrubbed, isomerization-zone net gas stream is combined with a reforming-zone net gas stream that comprises hydrogen and C 6 - hydrocarbons in a re-contacting zone to form a combined net gas stream that comprises hydrogen and light end hydrocarbons.
- the combined net gas stream is compressed with a compressor that is in the re-contacting zone to form a compressed combined net gas stream.
- a reforming-zone product stream that comprises C5+ hydrocarbons including aromatics is introduced to the re-contacting zone.
- the light end hydrocarbons is extracted from the compressed combined net gas stream in the re- contacting zone using the reforming-zone product stream to form a hydrogen-rich net gas stream and an aromatics-containing product stream.

- FIG. 2 schematically illustrates a paraffin isomerization section of the apparatus depicted in FIG. 1;

- FIG. 4 schematically illustrates a re-contacting zone of the hydrocarbon reforming section depicted in FIG. 3.
- Various embodiments contemplated herein relate to methods for recovering hydrogen from isomerizing and reforming of hydrocarbons. Unlike the prior art, the exemplary embodiments taught herein combine an isomerization-zone net gas stream from a paraffin isomerization section with a reforming-zone net gas stream from a hydrocarbon reforming section. Prior to combining the two streams, the isomerization-zone net gas stream is scrubbed to remove chloride-containing compounds including HCl to protect the downstream equipment.
- the reforming-zone net gas stream comprises hydrogen and C 6 - hydrocarbons and the isomerization-zone net gas stream comprises hydrogen and C 6 or lighter hydrocarbons.
- C x means hydrocarbon molecules that have "X” number of carbon atoms
- C x + means hydrocarbon molecules that have “X” and/or more than “X” number of carbon atoms
- C x - means hydrocarbon molecules that have “X” and/or less than “X” number of carbon atoms.
- C x and lighter and hydrocarbons means hydrocarbon molecules having "X” and less than "X” number of carbon atoms.
- the two streams combine to form a combined net gas stream that comprises hydrogen and light end hydrocarbons.
- the combined net gas stream is compressed via a compressor in the hydrocarbon reforming section to form a compressed combined net gas stream.
- the compressed combined net gas stream is passed through a re-contacting zone of the hydrocarbon reforming section.
- the light end hydrocarbons are extracted from the combined net gas stream using a reforming-zone product stream that comprises C 5 + hydrocarbons to form a hydrogen-rich net gas stream.
- Overall hydrogen recovery is improved for isomerizing and reforming of hydrocarbons because the hydrogen-rich net gas stream includes hydrogen not only from the reforming-zone net gas stream but also from the isomerization-zone net gas stream.
- the additional hydrogen recovered from the paraffin isomerization section is preferably accomplished with minimal additional equipment and cost because the hydrogen extracted from the isomerization-zone net gas stream is done using the hydrocarbon reforming section's existing equipment and re-contacting zone.

- the isomerization reaction-zone effluent 40 contains the branched paraffins, other hydrocarbons, and chloride-containing compounds including HC1.
- the isomerization reaction-zone effluent 40 is passed through the heat exchanger 36 and is cooled to a temperature of from about 65 to about 150°C.

- the combined feed exchanger 64 operates to exchange heat between a reforming-zone effluent 66 and the reforming-zone feedstock 62.

Regenerated catalyst from the regeneration zone 78 is introduced into the reforming reactor 74 via line 80.
- a reaction mixture is conducted from the reforming reactor 74 to the heater 70 and then the heated reaction mixture is returned to the reforming reactor 74.
