Lubes production  

ExxonMobil is the leading provider of advanced lubes manufacturing technologies that meet and exceed customer expectations for quality and profitability.

Our advanced hydroprocessing technologies provide maximum value through exceptional process performance for yield, run length and durability while producing outstanding product qualities.

  • MSDW™/MWI™/MAXSAT™ technology and service

    High-performance catalytic isomerization dewaxing is the preferred route for the production of the high-quality engine oil base stocks demanded by today’s vehicles. ExxonMobil’s proven lube catalytic dewaxing and hydrofinishing technology is typically installed as a two-reactor system and is capable of processing a very wide range of feedstocks, varying from hydrotreated or hydrocracked VGOs and DAOs to hydrotreated raffinates and slack waxes. Typical products are base stocks in the API Group II to III+ range, with viscosity grades as low as 2 and as high as 25 cSt at 100°C, depending on the feed.

    The Catalyst Makes All the Difference.

    With our system of proprietary shape-selective catalysts specifically designed to isomerize n-paraffins and saturate aromatics with maximum selectivity to lubes and minimal cracking to fuels, the true value of the yield advantage of the MSDW™ catalyst system will be quickly realized.


    • High selectively for some of the highest base oil yields, thus increases profitability
    • Demonstrated yield maintenance maximizes return on investment
    • Extremely high catalyst activity lowers capital cost (with smaller reactor design) and improves run length
    • High contaminants tolerance (>10 wppm nitrogen) improves stability and reliability
    • Full range of feed from light neutral to Bright stock
    • Valuable diesel fuel byproduct
    • Proven technologies and service with over 20 years of rigorous operating experience

  • Raffinate Hydrotreating (RHT)/ Raffinate Hydroconversion (RHC)

    ExxonMobil’s Raffinate Hydrotreating (RHT) and Raffinate Hydroconversion (RHC) technologies are commercially proven processes that can transform a Group I solvent lube plant into a Group II/II+/III advanced and flexible manufacturing facility in a cost effective way. RHT is ideally suited for operators that want to convert from Group I to Group II/II+/III production while retaining the existing solvent extraction plant. While RHC technology allows upgrade to Group II / II+ oils utilizing the existing solvent dewaxer and Group I lubes are processed only on the solvent extraction unit.


    • Leverage existing refinery infrastructure and process capacity
    • May result in significantly lower CAPEX investment than a new grass roots all-catalytic plant
    • Maximizes total lube production by optimizing severity between solvent extraction and RHC
    • Retains existing solvent dewaxing facilities preserving wax byproduct
    • Widely deployed, proven catalytic hydroprocessing technology
    • Robust design accommodates a wide range of crudes
    • Stable operation with long cycle life
    • Flexible operation able to adjust to saturates and VI by modifying solvent extraction and/or RHC severity
    • Adjust to NOACK needs with processing and back-end fractionation
    • Process full range of viscosity grades, or only selected ones to maximize value to refinery
