Lube dewaxing

Lube dewaxing  

ExxonMobil’s MSDW™, MAXSAT™ and MWI™ catalyst technologies produce high-quality, high-performing lubes base stocks. These technologies incorporate proprietary ExxonMobil catalysts and deliver outstanding activity, yield, selectivity, run length and durability. Our MSDW catalyst has demonstrated this for nearly 20 years. Our MAXSAT and MWI catalysts also deliver benefit-rich performance.

Continued technology advancement  

In today’s world, standing still corresponds to stepping backward. At ExxonMobil, we have active R&D to continue to boost yield, further improve tolerance to heteroatom contaminants and broaden the range of acceptable feedstocks.

MSDW, MAXSAT™ and MWI™ services include:  

  • Initial non-confidential consultations
  • Development of licensing proposal
  • Basic engineering package, including basic design specification and operating guide
  • Engineering support during FEED and EPC stages
  • Technology transfer, training, catalyst loading and startup support
  • Performance estimates for catalyst refills

Catalytic dewaxing technology  

The process is a system of proprietary catalysts containing zeolites and noble metals. They are designed to isomerize n-paraffins and saturate aromatics with maximum selectivity to lubes and minimal cracking to fuels. These catalysts display superior activity and unsurpassed tolerance to nitrogen, sulfur and aromatic contaminants in the feed. Even degradation in feed quality will require only a temporary increase in operating temperature with minimal impact on aging and virtually no impact on product yield.

Increase profits and add flexibility  

To put the value of the yield advantage of the MSDW catalyst system in context: For an average MSDW unit, at current product prices, a difference of 1% in yield of base stock product is worth between $2 million and $4 million per year over producing diesel fuel, or about $7 million to $8 million per year in revenues. When you operate an MSDW unit, even the byproduct is valuable. The majority of the conversion product from the MSDW catalyst system is diesel fuel with essentially no sulfur, an excellent cetane number and outstanding low temperature properties. This product is often blended with other distillates to increase the quality of the diesel pool, or supplement sources of arctic-grade diesel.
