Bottom-of-the-Barrel and Residue Upgrading Solutions
Bottom-of-the-barrel (BoB) in refining refers to the heavy residues in crude oil. Historically, the main use has been as fuel for the shipping industry (bunker fuel) and power generation. Demand for residual fuel oil has decreased for many decades, making it one of the lowest-value streams from refining. With the IMO2020 sulphur regulation for marine bunker fuels, demand will decrease drastically again. Refiners globally are looking into options for fuel-oil reduction or elimination all the way to a “bottomless” refinery, resulting in strong demand for bottom-of-the-barrel technologies.
Our Residuum Oil Supercritical Extraction (ROSE®) solvent de-asphalting technology recovers high-value products from residue streams that would otherwise be lost to low-value fuel oils. ROSE uses up to 60% less energy with supercritical solvent recovery and specially designed heat-recovery exchangers.
Our Veba Combi-Cracking (VCC) technology was developed through decades of research and innovation, resulting in this unique solution capable of processing a variety of feedstocks — from refinery residues to coal. With 95% conversion in a single pass, VCC enables the production of fuels that meet environmental specifications without further upgrading.
Our Asphaltene integrated Management Solution (AiMS) offers the opportunity to solidify the asphaltene removed in the ROSE process for easier handling and sales.
Our Asphaltene integrated Generation System (AiGSSM) enables use of the pitch generated from the ROSE process for steam and power generation.
Our Fluid Catalytic Cracking (FCC) technology is based on decades of continuous improvements and broad commercial experience and can be designed specifically to handle heavier residues for upgrading into valuable components.
Clean Fuel and High-Octane Solutions
Global demand for motor fuels continues to rise to record levels, while stricter environmental standards and oxygenate-blend requirements for gasoline place a premium on clean-burning, Low Reid Vapour Pressure components.
A safer, low-cost alternative for high-quality alkylate production, featuring a revolutionary solid catalyst engineered to overcome stability limitations, maximise the yield of motor fuels and enhance the production of ultra-clean blendstock.
The technology of choice for low-cost production of high-octane isomerate free of benzene and other aromatics, oxygenates and olefins. Features a compact, energy-efficient design using a regeneratable catalyst that isomerises and separates the iso-paraffin products and efficiently recycles n-paraffins within the same distillation column.
A proven technology for the dimerization of isobutylene to iso-octene and hydrogenate to iso-octane. Produces clean-burning, non-aromatic hydrocarbons with premium octane values from a wide variety of C4 feedstocks at minimum costs. Yields an olefinic or completely saturated product to increase production of higher grades, and can be adapted to produce MTBE, ETBE and more.
NExTAEE™ & NExTAME™
The optimum process technologies for producing fuel ethers from C5–C7 tertiary olefins, combining fixed-bed reactors with a distillation column to reach extremely high conversion rates, form TAME and TAEE, and yield a product mixture with maximal fuel ethers and unreacted hydrocarbons that can be used as a component in reformulated gasoline.
Our combined ethers technology, capable of processing any olefinic hydrocarbon feed in the C4–C7 range to produce MTBE, TAME and heavier ethers, as well as ETBE and TAEE in a single unit and at a low cost by bringing together alcohol recovery and circulation with oxygenate removal.
Petrochemical Integration & Olefin Yields
Petrochemical demand is expected to outpace growth in traditional refining capacity in the decades ahead. Refineries can benefit from increased production of naphtha — a main feedstock for the production of olefins and aromatics — as well as attractive margins and price stability from increasing yields for ethylene, propylene and aromatics.
This FCC process enables refiners to maximise propylene production by 20% or more with significantly less ethylene than traditional steam cracking, with the flexibility to operate as a conventional FCC to produce gasoline, depending on changing market demands.
Our catalytic olefin technology converts low-value olefinic, paraffinic or mixed streams into high-value propylene, ethylene and aromatics through the combination of the KBR Orthoflow™ FCC reactor system and a proprietary catalyst, and offers feed flexibility, high yields, low maintenance and greater energy efficiency.
An extractive distillation process for the recovery of aromatics that does not require any proprietary solvents or additives. It offers lower CAPEX and OPEX, smaller plot space, reduced energy consumption and wider feedstock range compared with conventional liquid-liquid extraction processes. Can be integrated into refining and petrochemical operations.
Modern refineries are focused on expanding their conversion capacities. The Fluid Catalytic Cracking Unit (FCCU) is important because it converts larger, heavier molecules into shorter, more valuable molecules such as gasoline, distillate and olefinic gases. KBR has been on the forefront of FCC developments since the 1940s and continues to provide a wide array of proprietary and specialised solutions for refineries worldwide.
KBR delivers a portfolio of FCC solutions to meet refiners’ specific production goals, with the flexibility to adjust their product mix for market conditions. We offer FCC options for increasing propylene production, maximising diesel production, minimising environmental issues, processing low-value residue streams and processing bio-feed and other non-traditional feed stocks.
This FCC process enables refiners to maximise propylene production by 20% or more with significantly less ethylene than traditional steam cracking, and it provides the flexibility to operate as a conventional FCC to produce gasoline depending on changing market demands.
Our flexible, cost-efficient FCC solution repurposes existing FCC units to increase diesel yields with a reduced capital investment. Turns high-quality, light-cycle oil into higher cetane products while offering the flexibility to revert to maximum octane barrels or maximum liquefied petroleum gas.
Hydroprocessing technologies include a wide array of hydrogenation, hydrocracking and hydrotreating solutions that can be found in all major refinery product streams. They are based on the use of hydrogen to remove impurities, resulting in cleaner products, or to break down carbon-carbon bonds, resulting in shorter, more valuable molecules.
Shell Global Solutions’ hydrotreating process, licensed by KBR, combines advanced process technology, high-performance catalyst systems and efficient internal reactor designs. Oil fractions react with hydrogen in the presence of a catalyst to produce high-value, clean products. Available in several configurations, including ones for the hydrotreating of naphtha, kerosene, diesel and VGO.
Shell Global Solutions’ hydrocracking technology, licensed by KBR, processes a wide range of feed qualities at different conversion levels, while meeting stringent fuel quality regulations. Heavy gas-oil fractions are partially converted to produce high-quality middle-distillate products, while the unconverted fractions are used as pretreated FCC or ethylene-cracker feedstocks, or lubricant base oils.

Distillation capacity controls the overall refinery throughput potential. Distillation is the separation of crude oil into different products based on their physical properties, such as boiling point.
Our advanced distillation configuration combines two distillation columns within a single shell to enable three or more products to be separated from a feed stream, offering superior fractionation performance and enhanced separation efficiency.
Crude and Vacuum Distillation
Shell Global Solutions technology, licensed by KBR, can help refiners to improve their distillation performance and “debottleneck” their operations through the licensing of bulk crude distillation units, high-vacuum units, work-up sections for upgrading units and column and vessel internals.
