HySWEET®: Hybrid Solvent Process for Improved Mercaptan Removal from Natural Gas
Industrial Performances


Progressive solvent swap from amine to HySWEET® solvent on existing unit at Lacq (France) treating a natural gas containing 430 ppmv of mercaptans.

The HySWEET® Solvent

  • Addition of a selected physical solvent to an amine
  • Maximizes absorption of mercaptans with limited coabsorption of hydrocarbons (typically < 1% HC in acid gas)
  • Reduces reboiler energy compared to amine solvent (-10% to -15%)
  • Over 6 years of successful operational experience on commercial plants
