20120184794 | PROCESS FOR ISOMERIZING A FEED STREAM INCLUDING ONE OR MORE C4-C6 HYDROCARBONS - One exemplary embodiment can be a process for isomerizing a feed stream including one or more C4-C6 hydrocarbons. Generally, the process includes contacting the feed stream in an isomerization reaction zone with an isomerization catalyst at isomerization conditions to produce an isomerization zone effluent; passing at least a portion of the isomerization zone effluent to a stabilizer zone and recovering a stabilizer overhead stream, a bottom stream, and a side-stream; passing at least a portion of the side-stream to a stripper zone; and sending a stripper bottom stream to a C5 splitter zone and passing a stream from the C5 splitter zone to the isomerization reaction zone. Generally, the stabilizer overhead stream can include one or more C5 | 07-19-2012 |
20130096356 | METHODS AND APPARATUSES FOR THE ISOMERIZATION AND DEISOHEXANIZING OF HYDROCARBON FEEDS - Methods and apparatuses for the isomerization and deisohexanizing of a feed are provided. In a method for the isomerization of a feed in an isomerization zone to form an isomerized stream and the deisohexanizing of the isomerized stream in a deisohexanizer zone, heat is exchanged between the isomerization zone and the deisohexanizer zone to raise the temperature of the feed and to reduce the temperature of the deisohexanizer sidecut stream. | 04-18-2013 |

20140094632 | METHODS AND APPARATUSES FOR RECOVERING NORMAL HEXANE FROM REFORMATE STREAMS - Methods and apparatuses for recovering normal hexane from a reformate stream are provided. In one example, a method for recovering normal hexane from a reformate stream includes extracting aromatics from the reformate stream to form an aromatic extract stream and a raffinate stream. In the method, the normal hexane is separated from the raffinate stream to form a normal hexane product stream. | 04-03-2014 |

20140128647 | METHOD AND APPARATUS FOR REDUCING AN AROMATIC CONCENTRATION IN A HYDROCARBON STREAM - Methods and apparatuses for reducing an aromatic concentration in a hydrocarbon stream are provided. In an embodiment, a method for reducing an aromatic concentration in a hydrocarbon stream includes saturating aromatics in the hydrocarbon stream to form a low aromatic hydrocarbon stream comprising no more than about 2 weight percent (wt %) aromatics. Further, the method includes passing the low aromatic hydrocarbon stream through an adsorption zone to remove aromatics therefrom to form an aromatic-depleted product stream comprising less than about 10 weight parts per million (wppm) aromatics. | 05-08-2014 |
