H2S Scavengers for Asphalt | VALIREX Zinc  

Zinc-based Metal Carboxylates to Reduce Hydrogen Sulfide Levels in Asphalt Streams

Asphalt, a residue of the thermal separation refinery process of petroleum, is known for containing hazardous hydrogen sulfide. Our VALIREX/VALIKAT zinc carboxylates are high-quality zinc-based metal carboxylates, used as treatment chemicals for high H2S scavenging efficiency in asphalt streams. Our products ensure the safety of your operations. 

In the bitumen industry, it's crucial to maintain safe levels of hydrogen sulfide to prevent employee exposure to toxic fumes. By reducing H2S to safe levels, we ensure secure loading, handling, and storage of asphalt. Trust us to provide the solution you need to maintain a safe and healthy work environment
