DMDS Evolution® E2 composition:

DMDS Evolution® E2 properties:

  • Liquid over a wide range of temperature: DMDS remains liquid in a large range of temperature (from -85 °C to 109 °C), which makes it easy to handle, transfer and inject. 

 

  • The highest sulfur content on the market: With a sulfur content of 68 %,  DMDS Evolution®E2 is the standard sulfur carrier available to reduce coking in you steamcrackers and for catalysts sulfiding. 

 

  • Outstanding performance with superior scent: DMDS Evolution®E2 is a breakthrough formulation for outstanding odor control and safe handling operations. It provides a pleasant fragrance. 

 

  • High solubility: DMDS evolution® E2 shows the best solubility in hydrocarbons for a perfect reaction on all hydrogenation catalysts.  

 

  • Perfect vaporization profile: With a boiling point of 109 °C, DMDS Evolution® E2 ensures an homogenous distribution in all steamcrakers tubes. 

 

  • Oustanding performances for sulfiding and anti-coking applications. 

Applications:

DMDS FOR CATALYST SULFIDING
