SULFUR POLISHING FOR LIGHT FEEDS
Reduce sulfur and nitrogen content in distillates and crudes to ultra-low levels, without hydrogen
Auterra’s FlexULS™ is a novel adsorption-based process that effectively treats any crude oil, distillate, or petrochemical stream containing sulfur levels below 1,000 ppm. Treated streams see sulfur reduction down to less than 10 ppm and a 25-60% reduction in nitrogen, with no saturation or oxidation of the stream.

FlexULS™ is a scalable, cost-effective desulfurization alternative for producing in-spec fuels
The FlexULS™ design includes fixed bed reactors with our proprietary adsorbent that separates impurities at ambient temperature, with no hydrogen required, and no induced pressure needed. The small physical footprint and low capital costs of FlexULS™ units make it an ideal solution for producers needing to meet ultra-low sulfur performance levels.
