OASE® sulfexx™ for Selective Treatment

 

OASE® sulfexx™ is a highly energy efficient gas treating technology jointly developed by ExxonMobil and BASF, which helps refiners and gas processors to meet their sulfur removal targets while reducing carbon footprint. OASE® sulfexx™ provides a competitive advantage by increasing plant capacity and lowering investment and production costs.

Raising the bar for selective H2S removal

 

OASE® sulfexx™ solvent enables selective removal of hydrogen sulfide (H2S) while minimizing the co-absorption of carbon dioxide (CO2). The new solvent is based on a new proprietary amine that allows gas treatment units to achieve high absorption capacity with low energy consumption for regeneration. The result is lower operating costs, smaller equipment, and lower capital investments than conventional amine gas treatment units.

Best fits 

  • Natural gas to pipeline

  • Natural gas to power

  • Claus tail gas treatment

  • Enhances oil recovery

  • Suitable for warmer climates

Tested and proven 

Suitable for both low and high pressure gas treatment, the solvent provides superior performance characteristics over MDEA (methyldiethanolamne) solvents in Claus tail gas treating, acid gas enrichment, and acid gas removal applications.

When used in a tail gas treating unit in conjunction with a Claus sulfur recovery unit (SRU), the new technology has the capability to achieve greater than 99.99% overall sulfur recovery and very low emissions to cope with future requirements. Commercially demonstrated to show superior performance characteristics over MDEA formulations and even improvements over FLEXSORB™ SE/SE PLUS solvents.
