DMDS Evolution® E2 for anti-coking in Propane and Butane Dehydrogenation units

Discover the Product range DMDS sulfiding & anti-coking solution.
Product overview

Dimethyl disulfide, DMDS Evolution® E2, is the leading sulfur-based, anti-coking and corrosion inhibition technology that is used globally in Propane Dehydrogenation (PDH) and Butane 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 Propane and Butane Dehydrogenation units process by reacting with the metal surface in the catalytic reactors 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, while improwing the user working conditions.
  • Corrosion inhibition / Anti-coking agent of choice: DMDS Evolution® E2 has been successfully adopted as the standard corrosion inhibitor agent of choice for Propane and Butane Dehydrogenation units globally.

DMDS Evolution® E2 benefits for Propane and Butane Dehydrogenation units


Protects your propane and butane dehydrogenation units and allows for more valuable production time.


Delivers a better scent than standard DMDS, improving the user experience.


Provides the needed coke prevention when used in low quantities (<100 ppm).


Approved by Major Technology Licensors as the only sulfur compound for PDH and BDH units.
