Abstract:
1. A process for isomerizing a feed stream comprising one or more C4-C6 paraffins, comprising: A) contacting the feed stream in an isomerization reaction zone with an isomerization catalyst at isomerization conditions to produce an isomerization zone effluent; B) passing at least a portion of the isomerization zone effluent to a stabilizer zone and recovering a stabilizer overhead stream comprising one or more C5 C) passing at least a portion of the side stream to a stripping zone and separating the side stream into a stripper overhead stream comprising at least about 5% by weight one or more C4 (D) passing at least a portion of the stripper bottom stream to a deisopentanizer zone comprising a deisopentanizer column; and (E) passing a bottoms stream from the deisopentanizer zone to the isomerization reaction zone.
