Abstract
Official abstract text for this publication.
An integrated upgrading process for upgrading a heavy oil, the process comprising the steps of introducing a heavy oil to a visbreaker unit; processing the heavy oil in the visbreaker unit to produce a visbreaker product stream; feeding the visbreaker product stream to a fractionator; separating the visbreaker product stream in the fractionator to produce a bottoms stream, a gas oil stream, a naphtha stream, and a gas product stream; feeding the bottoms stream to a supercritical water unit; and processing the bottoms stream in the supercritical water unit to produce an upgraded bottoms stream.
First claim
Opening claim text (preview).
That which is claimed is: 1. A system for upgrading a heavy oil, the system comprising: a supercritical water unit, the supercritical water unit configured to process the heavy oil to produce an upgraded heavy oil; a mixer fluidly connected to the supercritical water unit and a visbreaker unit, the mixer configured to mix the entirety of the upgraded heavy oil with the entirety of a visbreaker product to produce a mixed product stream; a fractionator fluidly connected to the mixer, the fractionator configured to separate the mixed product stream to produce a bottom fraction; and a visbreaker unit fluidly connected to the fractionator, the visbreaker unit configured to process the bottom fraction to produce the visbreaker product. 2. The system of claim 1 , wherein the heavy oil is selected from the group consisting of a vacuum residue, an atmospheric residue, a fluid catalytic cracking clarified slurry oil having a T5% cut point of greater than 600 deg F., a naphtha steam cracker pyrolysis fuel oil, and residue streams.
