Abstract

A process for hydroprocessing a hydrotreated liquid distillate stream to produce a stream exceptionally low in sulfur as well as aromatics. A hydrotreated distillate stream is further hydrotreated in a co-current reaction zone wherein the reaction product is passed to a separation drum wherein a vapor product is collected overhead and a liquid product is passed to a aromatics saturation zone countercurrent to the flow of hydrogen treat gas.
