Sulfur recovery is a crucial process in various industries, especially those involved in refining petroleum and natural gas. Sulfur-containing compounds in these raw materials can be harmful to the environment and pose health hazards. The Claus process, a time-tested and reliable method, effectively recovers sulfur from these sources, ensuring cleaner emissions and compliance with environmental regulations. Claus Catalysts are an important part of the Claus process. They are essential in promoting the chemical reactions required for efficient sulfur recovery. These catalysts act as agents to accelerate the conversion of hydrogen sulfide (H2S) and sulfur dioxide (SO2) into elemental sulfur (S8), a valuable and safe byproduct. Evonik manufactures and supplies the Claus and Tail Gas catalysts needed to achieve and maintain high sulfur recovery efficiency.
