Claus plant sulfur recoveries (97-98%) are not high enough to comply with increasingly stringent environmental legislation. To achieve compliance, several Claus Tail Gas Treatment (TGT) processes have been developed. Axens provides catalysts for reductive TGT processes enabling overall sulfur recoveries in excess of 99.9%.
Axens has a long history concerning TGT catalysts: from the original SulShine® TG 103 and its descendant SulShine® TG 203, to the SulShine® TG 107 and SulShine® TG 136, the most active CoMo catalysts specially conceived for low-temperature processes.
SulShine®: The Sulfur Recovery Catalysts of choice to meet environmental regulations. Axens offers a wide portfolio of industrially proven, high-performance, and top-conversion Sulfur Recovery Catalysts. They cover Claus units and Tail Gas Treatment units in oil refining and natural gas complexes, delivering the outstanding performance required by operators to succeed in these highly competitive industries. In the range of low-temperature TGT Catalysts, SulShine® TG 308 offers optimized metal active sites distribution on a low density spherical carrier.
