Abstract

A process and apparatus provides alternative hydrotreating reactor trains for hydrotreating a hydrocarbon stream. One hydrotreating reactor train is smaller than the other and the smaller train comes on stream to allow replacement or regeneration of catalyst in the larger train. A sulfide system also sulfides the catalyst volume in the reactor train that is off stream to prepare it for renewed hydroprocessing of feed when back on stream. The process and apparatus can be used to keep hydroprocessing reactors on stream to continuously provide feed to an FCC unit which has a longer period before shut down.

Claims11

Dependent claims

A process for hydroprocessing a hydrocarbon stream comprising:

feeding said hydrocarbon stream and a hydrogen stream to a first volume of hydroprocessing catalyst to hydroprocess said hydrocarbon stream in the presence of said hydrogen stream to provide a first hydroprocessed stream;
terminating feed of said hydrocarbon stream to said first volume of catalyst;
and feeding said hydrocarbon stream and said hydrogen stream to a second volume of hydroprocessing catalyst, said second volume being smaller than said first volume of catalyst to hydroprocess said hydrocarbon stream in the presence of said hydrogen stream to provide a second hydroprocessed stream, wherein said first hydroprocessed stream is fed to a fluid catalytic cracking reactor before said termination step and feeding said second hydroprocessed hydrocarbon stream to said fluid catalytic cracking reactor after said termination step.

Dependencies are inferred from the claim text.
