The petrochemical industry uses our products in two ways. Dimethyl Sulfide (DMS) and Dimethyl Sulfoxide (DMSO) are used to modify the reactivity of industrial catalysts (catalyst presulfiding). DMS is an important sulfidation agent in the steamcracking process to make olefins like ethylene and propylene.
DMSO has an unusual affinity for aromatic hydrocarbons over aliphatic hydrocarbons. This allows their use as extractants for BTX (benzene/toluene/xylenes) and other aromatics, from mixture also containing aliphatic hydrocarbons.
DMS and DMSO are popular sulfur sources for regulating catalyst activity in catalytic reforming, hydrodesulfurization, and hydrocracking industrial processes.
Olefin furnace run length is prolonged when treated with DMS, and CO levels are controlled.
DMS has advantages over common gas odorants.
The service lifetime of furnace tubes used to produce iron is prolonged when treated with DMSO and DMS.
