Gas treating  

To help refiners and gas processors meet their sulfur removal targets and today’s stringent emission regulations, we provide world-class gas-treating technologies. Jointly developed by BASF and ExxonMobil, OASE® sulfexx™ technology provides selective sulfur removal and high energy efficiency. FLEXSORB™ SE and FLEXSORB™ SE Plus technologies are designed for selective removal of H2S in the presence of CO2 using proprietary severely sterically hindered amines.

These exceptional gas-treating technologies are designed to enable:

  • Low operating costs and energy consumption
  • Low capital costs
  • Environmental benefits
