Sulfur Recovery Units (SRU) convert unwanted hydrogen sulfide (H2S) and sulfur dioxide (SO2) to the desired element, sulfur. This is done most often using the Claus process.
SRUs are essential parts of natural gas plants, refineries and smelters, where large amounts of H2S are produced. The quality of the Claus Catalyst is critical for maximizing the performance of the SRU.
BASF has the most extensive line of Claus Catalysts in the industry. In addition to non-promoted and promoted activated alumina, we offer two different titania catalysts along with an alumina/titania composite catalyst. Our product portfolio is completed by CoMo catalysts for SRU Tail Gas Treatment Unit (TGTU) applications.
