Ethylene Production

Furnace tube treatment. Dimethyl Sulfide is used to prevent the build-up of coke deposits in pyrolysis furnaces used to manufacture ethylene. Coke formation is a persistent problem in ethylene production. Coke can decrease the flow of ethylene as it accumulates in furnace tubes. It also acts as an insulator in the tube, requiring higher heat input to maintain furnace performance. DMS can be used as an additive in the gas feed to inhibit the formation of coke in the furnace tube and minimize these issues.

Additionally, coke build-up leads to carburization, which involves the diffusion of carbon into the metal of the furnace. This leads to premature failure of the furnace tube, and an associated maintenance/repair expense.
