Abstract
One exemplary embodiment can be a hydrotreating process. The hydrotreating process can include providing a first feed stream having a coker naphtha with a bromine number of about 10-about 120, combining the first feed stream with a second feed stream having a straight run naphtha with a bromine number of less than about 10 to create a combined feed, providing the combined feed to a hydrotreating reactor having at least one catalyst bed, and separating a quench stream from the second feed stream and providing the quench stream after the at least one catalyst bed.
Claims18
A hydrotreating process, comprising:
- A) providing a first feed stream comprising a coker naphtha with a bromine number of about 10-about 120;
- B) combining the first feed stream with a second feed stream comprising a straight run naphtha with a bromine number less than about 10 to create a combined feed;
- C) providing the combined feed to a hydrotreating reactor having at least one catalyst bed;
- and
- D) separating a quench stream from the second feed stream and providing the quench stream after the at least one catalyst bed.
A process for controlling a temperature in a reactor, comprising:
- providing to the reactor a quench stream comprising a naphtha having a bromine number of less than about 10, and a feed stream comprising a naphtha having a diene value of greater than about 2 and a bromine number of about 10-about 120 and splitting a portion of another feed stream comprising a straight run naphtha as the quench stream and combining a remaining portion of the another feed stream with the feed stream to the reactor.
A process for hydrotreating a coker naphtha while minimizing a liquid recycle, comprising:
- providing a naphtha having an effective amount of olefins and diolefins as a quench stream to a hydrotreating reactor;
- and
- combining a portion of said naphtha with a coker naphtha with a bromine number of about 10-about 120;
- and
- providing the combined feed to a hydrotreating reactor having at least one catalyst bed.
