Octane Booster
Boost octane and throughput of light naphtha (C5–C6) isomerization units without new columns — DWC Prime retrofits into the existing deisohexanizer.
Explore technology →
Food Grade Hexane
Revamp the deisohexanizer to produce a valuable 4th cut — food-grade, polymer-grade or isohexane — raising isom-unit capacity by 20%+.
Explore technology →
Benzene Saturation
Ben Prime technology manages benzene in the gasoline pool with a cost-effective saturation solution that meets stringent regulatory requirements.
Explore technology →
CS₂ Removal
DWC Prime technology reduces carbon disulfide (CS₂) contamination in petrochemical naphtha to below 2 ppm, protecting downstream catalysts and equipment.
