Delivery of the sulfiding agent

Once a desired delivery date is selected, Arkema allocates the requested high quality DMDS and establishes the most suitable logistics to meet your sulfiding schedule. We can also recommend a container or containers most suitable to your situation: road tankers, semi-bulk and bulk containers (such as ISO containers) are all available. During the last few weeks leading to activation, an Arkema representative keeps in close contact with the refinery to adjust the final delivery date to any unexpected change of the unit turnaround schedule.

Optimize your sulfidings, maximize your runtime

Process equipment changes, new operators, catalyst selection and loading may each have an impact on the safety and efficiency of your unit start-up. Training and procedure review are important preparation steps for your catalyst activation. Arkema provides training in the fundamentals of catalyst sulfiding. We teach the DMDS chemistry, the sulfiding stages, and pathways to generate H2S via the “efficient sulfur” concept. Our expert help in procedure review and training, utilizes Arkema’s position as a global leader in organosulfur chemistry and our vast experience with catalyst sulfiding.

Service innovation

Thanks to our customer’s confidence and market recognition for Carelflex® top-quality service, Arkema has extended its service portfolio to other applications or other chemical injections: 

1. DMDS injection for Hydrogenation of Vegetal Oils (HVO) plants based on the same catalysts as those used in refineries, these biorefineries produce renewable diesel or jet fuels. Very similar DMDS supply and injection service is required for their hydrotreating catalyst sulfidings.
