1. A system for external processing of flash zone gas oil from a delayed coking process, which comprises:
- a vacuum residuum hydroprocessing unit for converting the flash zone gas oil by one of ebullated bed hydrocracking and dispersed catalyst hydrocracking;
a delayed coking process system for producing the flash zone gas oil;
a flash zone gas oil line in fluid communication between the vacuum residuum hydroprocessing unit and the delayed coking process system for carrying only the flash zone gas oil from the delayed coking process system to the vacuum residuum hydroprocessing unit; and
a feed line in fluid communication between the vacuum residuum hydroprocessing unit and the delayed coking process system for carrying a vacuum residuum feed comprising unconverted flash zone gas oil from the vacuum residuum hydroprocessing unit to the delayed coking process system.
