The sulfiding process is a major operation. As the world leader in thio-chemicals, Arkema manufactures dimethyl disulfide (DMDS), an effective product with a high sulfur content. When used as a sulfiding agent, it can be combined with a personalized service called Carelflex® which offers users on-site technical assistance.

DMDS is used in a wide variety of applications, including:

• Oil refining: optimal maintenance of production units. DMDS is used in oil refineries as a sulfiding / presulfiding agent to activate the catalysts of hydrotreating units. This is an indispensable but delicate operation. That is why Arkema offers its clients Carelflex®, an on-site sulfiding service carried out by highly qualified technicians. Arkema has also developed an improved, lower odor version of DMDS called DMDS Evolution™.

   

• Petrochemicals: to reduce the number of decoking operations. Operators in the petrochemicals industry must protect their steamcracking coils against the formation of coke and carbon monoxide. DMDS by Arkema is the ideal sulfurous product for them. DMDS can be added continuously to the raw materials to maintain an optimal sulfur level, making it possible to reduce the number of decoking operations. The secondary reactions to these operations are easier to control and the production cycles are lengthened.

DMDS is also used in various other sectors, including:

• Fine chemicals, as chemical intermediate
• Metallurgy for its anti-corrosion properties.
