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.

Aromatic Extraction

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.

Catalyst Presulfiding

DMS and DMSO are popular sulfur sources for regulating catalyst activity in catalytic reforming, hydrodesulfurization, and hydrocracking industrial processes.

Ethylene Production

Olefin furnace run length is prolonged when treated with DMS, and CO levels are controlled.

Gas Odorant

DMS has advantages over common gas odorants.

Iron Ore Reduction

The service lifetime of furnace tubes used to produce iron is prolonged when treated with DMSO and DMS.
