DMDS Evolution® E2 for anti-coking in PDH & BDH
Dimethyl disulfide, DMDS Evolution® E2, is the leading sulfur-based, anti-coking and metallurgy protection technology that is used globally in Propane Dehydrogenation (PDH) and IsoButane Dehydrogenation (BDH) units. Hydrocarbons exposed to elevated temperatures form coke, which can cause metal carburization and affect heat transfer and flow dynamics. In less than 15 minutes, sufficient coke is formed to require dehydrogenation unit shut down for immediate cleaning and decoking. This anti-coking method is superior in performance and generally preferred compare to physical pipeline, cracker coating or polishing.
Improve efficiency by reducing non-production down-time
DMDS Evolution® E2 injection prevents coke formation in hot areas of the PDH & BDH process by reacting with the metal surface in the cracker to form a protective coating, so your units can continue running efficiently and effectively.
DMDS Evolution® E2 properties
- Delivers an optimal release of H2S: At 400 °C, DMDS Evolution® E2 starts to release H2S and decomposes completely by 600 °C. The decomposition of our product enables the formation of a protective layer of sulfur to prevent coke formation in your installation
- DMDS Evolution® E2 is a breakthrough formulation for a better smelling DMDS sulfiding agent. It outperforms in odor control, and provides a more pleasant fragrance
- Anti-coking agent of choice: DMDS Evolution® E2 is a drop-in replacement for DMDS. It has been successfully adopted as the sulfiding and anti-coking agent of choice at all major refineries, steam-crackers and definitely PDH & BDH units globally
DMDS Evolution® E2 benefits in PDH & BDH
Protects your PDH & BDH units and allows for more valuable production time
Provides the needed coke prevention when used in low quantities (<100 ppm)
Delivers a better scent than standard DMDS, improving the user experience
Approved by Major Technology Licensors as the only sulfur compound for PDH and BDH units
