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.
