Residue Upgrading
Today’s refiners need to maximize the returns out of every barrel of oil. The decision on which technology to use to upgrade residue is an important one, with long-term impacts and economic consequences.
UOP offers various solutions for upgrading both atmospheric and vacuum residue streams.
The choice of technologies depends upon both the quality of the resid stream and the quality of the final fuel products produced. Slurry hydrocracking, such as UOP’s UniflexTM process family, offers the maximum amount of upgrading and produces zero fuel oil.
UOP’s residue upgrading portfolio includes a range of solutions that will help you to achieve your unique processing objectives, including:
-
Slurry Hydrocracking
The UOP Uniflex™ process offers maximum conversion (90% +) that is selective to transportation fuels and minimizes production of residue byproduct. This process provides an optimal solution for minimizing fuel oil production.
-
Resid FCC
The UOP RFCC Resid FCCTM™ process is a cost-effective means for converting moderate to severely contaminated feedstocks to gasoline and lighter components.
-
Residue Hydrotreating
The UOP RCD Unionfining™ process is a residue hydrotreating process that removes contaminants and adds hydrogen for downstream Resid FCC processing. It can sometimes be used to produce low sulfur fuel oil.
-
Coking
The FWUSA SYDEC™ delayed coking process is a severe thermal conversion process that produces a wide range of products. Once hydrotreated, these products can be processed in other refinery processes and a byproduct residue coke.
-
Solvent Deasphalting
The UOP/FWUSA Solvent Deasphalting process separates residue into high quality, low contaminant level deasphalted oil for downstream hydrocracking, or FCC/RFCC units. The UOP/FWUSA Visbreaking process is a low-cost process that reduces viscosity of residues to minimize “cutter” stock in addition to making residue fuel oil.
