Vacuum Gas Oil Conversion

FCC, Unicracking, and VGO Unionfining processes are the keys to cost-effective upgrading of Vacuum Gas Oil.

These treating and conversion technologies, used alone or more typically in combination, can produce a wide range of diesel/gasoline ratios while meeting stringent product specifications. Feedstock blends of VGO and deasphalted oil, coker gas oils, and residue hydroprocessing products can also be effectively upgraded to further increase net fuel oil conversion.

Unmatched experience combined with continuous innovation

View Larger ImageFCC The UOP FCC process can help you achieve your refining and petrochemical objectives by converting straight-run atmospheric gas oils, vacuum gas oils, certain atmospheric residues and heavy stocks recovered from other refinery operations into high-octane gasoline, light fuel oils and olefin-rich light gases like propylene for petrochemical use and butenes needed for the alkylation process. UOP first developed FCC technology in the 1940s, but we continue to evolve this technology focusing on continuous process-design innovation. Many of today’s state-of-the-art FCC units utilize advanced technologies to enhance catalytic cracking and reduce thermal cracking for significantly higher yields of desired products. Recent UOP advancements include:

Custom solutions to increase your profitability

Hydrocracking

The industry-leading UOP Unicracking™ process can produce LPG, naphtha, kerosene and diesel, as well as high-quality unconverted oil for use downstream in the production of lube oils.  The process can also produce FCC feed through the conversion of heavier feedstocks and the addition of hydrogen.

Adding in the power of our complete portfolio of hydrocracking catalysts, UOP hydrocracking solutions are designed to improve your overall profitability. Through significant advances in catalyst technology, we can increase the precision of reaction chemistry on a molecular level, and provide a tailored solution that will allow you to be more specific and selective to achieve your processing goals. Whether you are looking to produce maximum diesel or naphtha, our solutions can be tailored to allow for flexible operation between the two extremes based on your regional market needs.

We offer multiple Unicracking flow schemes and we can customize our single-stage and two-stage designs to meet your specific objectives. With more than 200 units awarded in over 40 countries and 50+ years of history in Hydroprocessing, we bring the right capabilities and experience to help you improve your bottom line.

UOP’s continued advances in the design of hydroprocessing units and reactor internals like the Alliance Hydroprocessing Reactor Internals can maximize your profits by achieving the best possible performance from hydroprocessing units at the lowest possible cost.

Optimizing hydrogen content for FCC unit feed

Hydrotreating

The UOP VGO Unionfining™ process provides better quality and higher yields of FCC gasoline with lower yields of FCC light and heavy cycle oils within the FCC unit. The typical application of this technology is FCC feed pretreatment. The feeds that can be processed in the VGO Unionfining process include straight-run vacuum gas oil, heavy coker gas oil and visbreaker gas oil. This process can also be used to produce low sulfur fuel oil.

Our solutions include a full range of world-class hydrotreating catalyst solutions offered via the UOP/Albemarle Hydroprocessing Alliance.  The alliance combines the strengths of UOP, a leading developer of hydrotreating and hydrocracking process technology and hydrocracking catalysts, and Albemarle, a leading developer and supplier of innovative refinery hydrotreating catalysts and technologies, to provide you with the broadest portfolio available of hydroprocessing solutions.

Balancing Distillate and Gasoline Production Across Hydrocracking and FCC Technologies

Mild hydrocracking can increase distillate production within your refinery complex. If you need to produce more high-quality distillate but still produce FCC feedstock, optimizing the UOP MHC Unicracking process with the FCC unit is critical.

This process can be used to increase distillate production in both new units and in revamps of existing FCC pretreating units while balancing the feed to the FCC unit and keeping it full. The feed balance and asset allocation need to be reviewed and optimized across the MHC Unicracking, FCC and Distillate Unionfining technologies for the optimum product quality and balance.

A one-stop-shop for premium lubes and fuels production

In July 2011, UOP and ExxonMobil Research & Engineering Company (EMRE) created an alliance to offer integrated solutions for the production of lube base oils and high-quality fuels.  This effort brings together leading UOP hydroprocessing technology, catalysts and equipment with EMRE Hydroisomerization dewaxing technology and other EMRE hydroprocessing solutions to produce high yields of low sulfur, ultra-clean diesel with excellent cetane and cold flow properties and lube base oils.

The alliance allows us to provide you with an integrated process design from a single engineering package to achieve impressive yields of fuels and lube products while optimizing your operating and capital costs. 

Produce high yields of ultra-clean diesel

The integration of UOP Unicracking and Unionfining solutions with EMRE MIDW isomerization dewaxing technology drives impressive yields of high-cetane, ultra-clean diesel.  Refiners will be able to upgrade the cold flow properties of distillate boiling range feedstocks and enable blending of distillate products to meet the stringent cold flow specifications required for certain regions.

Customers also have access to state-of-the-art hydrotreating catalysts available through the UOP hydroprocessing alliance with Albmemarle. 

Integrated, cost-efficient lubes production

Customers can utilize the UOP Unicracking process and catalysts for high-quality feedstock production along with a suite of EMRE solutions to achieve your lube production goals. 

  • The EMRE MSDW™ lube hydroisomerization technology upgrades lube blend stock by converting wax to high viscosity index (VI) lubes
  • The EMRE MAXSAT™ lube hydrofinishing technology improves color and stability of lube blend stocks while also saturating polynuclear aromatics
  • Other EMRE lube hydroprocessing technologies such as MWI for wax isomerization, RHC for raffinate hydroconversion, RHT for raffinate hydrotreating can enable solvent-based lube processing facilities to produce Group II and Group III lubes.
