DMS Exact-S® Grade is the standard olefins sulfidation agent in North America. It is added to gas and liquid feedstocks as they enter steamcracking furnaces and regulates the formation of carbon monoxide and controls the rate at which coke develops.
DMS Exact-S® Grade is manufactured in a way to minimize feedstock contaminant impurities which cause problems in steamcracking furnaces and downstream processes. These include carbon disulfide, methyl mercaptan, carbonyl sulfide and problematic metals.
It's key application is as a Sulfidation agent for ethylene production.
