Methods for treating vacuum gas oil (VGO) and apparatuses for the same

摘要

Embodiments of apparatuses and methods for treating a vacuum gas oil (VGO) hydrotreating feed are provided. In one example, a method comprises contacting the VGO hydrotreating feed with a first hydrotreating catalyst in the presence of hydrogen at first hydroprocessing conditions effective to form a first hydrotreated effluent. The first hydrotreated effluent is separated to form a hydrotreated VGO-containing stream and a hydrotreated diesel-containing stream. The hydrotreated VGO-containing stream is stripped and fractionated to form a VGO product stream. The hydrotreated diesel-containing stream is combined with a hydrotreated diesel-, naphtha-containing stream to form a combined stream. The combined stream is stripped to form a diesel product stream.

1. A method for treating a vacuum gas oil (VGO) hydrotreating feed that comprises primarily VGO and diesel range hydrocarbons, the method comprising the steps of:
contacting the VGO hydrotreating feed with a first hydrotreating catalyst in the presence of hydrogen at first hydroprocessing conditions effective to form a first hydrotreated effluent; separating the first hydrotreated effluent to form a hydrotreated VGO-containing stream and a hydrotreated diesel-containing stream; stripping and fractionating the hydrotreated VGO-containing stream to form a VGO product stream; combining the hydrotreated diesel-containing stream with a hydrotreated diesel-, naphtha-containing stream to form a combined stream; and stripping the combined stream to form a diesel product stream.
