Abstract
A process for increasing a yield of an isomerization zone by removing at least a portion of the C6 cyclic hydrocarbons from a stream having iC4 hydrocarbons, iC5 hydrocarbons, and iC6 hydrocarbons prior to the stream being passed into the same isomerization zone. Suppression of the iC4 hydrocarbons does not occur, allowing the iC4 hydrocarbons to be isomerized in the same isomerization zone as the iC5 hydrocarbons and iC6 hydrocarbons.
Claims20
A process for increasing a yield of an isomerization zone, the process comprising:
- separating a portion of C6 cyclic hydrocarbons from a naphtha stream comprising C4+ hydrocarbons to provide a C6 cyclic hydrocarbons lean stream;
- separating iC4 hydrocarbons, iC5 hydrocarbons, and iC6 hydrocarbons from the C6 cyclic hydrocarbons lean stream;
- and,
- passing at least one stream being rich in iC4 hydrocarbons, iC5 hydrocarbons, iC6 hydrocarbons, or a combination thereof to an isomerization zone.
A process for increasing a yield of an isomerization zone, the process comprising:
- removing C6 cyclic hydrocarbons from at least one stream comprising iC4 hydrocarbons, iC5 hydrocarbons, iC6 hydrocarbons, or combinations thereof, to provide a C6 cyclic hydrocarbons lean stream;
- and,
- passing the C6 cyclic hydrocarbons lean stream an isomerization zone.
