DMSO Enviro-S® is an environmentally-friendly alternative to the use of other sulfur chemicals in catalyst presulfiding, and ethylene furnace passivation. It offers a unique combination of low toxicity, low odor, and high sulfur content for use in the petrochemical industry.
Enviro-S is important in the presulfiding of hydrodenitrification (HDN), Hydrodesulfurization (HDS) and cracking catalysts.
Key Applications for DMSO Enviro-S®
- When low odor is an important operational concern, Enviro-S offers a proven sulfur source without the unpleasant odor of alternative process chemicals.
