A new highly energy efficient amine gas treatment technology named OASE® sulfexx™ released by BASF SE and ExxonMobil Catalysts and Licensing LLC. While minimizing the co-absorption of carbon dioxide (CO2) from gas streams, the technology is based on a new proprietary amine-based solvent that selectively removes hydrogen sulfide (H2S).
To increase capacity and lower operating costs on existing equipment, the companies jointly developed the amine-based solvent. Compared to conventional amine gas treatment units, the use of OASE sulfexx for new facilities will reduce the size of the equipment and the initial capital investment.
While rejecting CO2 to meet future emission requirements, the technology can achieve less than 10 ppmv H2S specifications in Claus tail gas treating units.
