Process of recovering elemental sulfur from H2S gas

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.

MAXCEL™

Technologies and services for sulfur recovery unit operators.

Evonik's range of technologies and services for sulfur recovery unit operators has grown over the years to include standard alumina Claus catalyst, low temperature tail gas treating catalysts, and everything in between.

EcoMax

EcoMax catalysts renewal brings the established technology of catalyst re-use to tail gas treating. In the patent-pending EcoMax process, spent hydroprocessing catalyst is treated to remove harmful contaminants and restore catalyst activity. This yields a tail gas catalyst that performs superior to many competitive tail gas catalysts – at a fraction of the cost and with minimal environmental impact.
