Within the refining and petrochemical industries, the removal of impurities plays a large part in catalyst efficiency and longevity.

Impurities, such as arsine, chloride and mercury, result in the poisoning of the catalyst and the corrosion of the steel equipment.

Our products remove these impurities:

  • Sulfur Removal 
  • Halogen Removal
  • Mercury Removal
  • Arsenic Removal
  • Hydrolysis
  • UNISORB Adsorbents

Our broad product line and Trademark Layered-Bed Design Technology has the flexibility to provide optimal purification performance, even in the most severe environments. Severity of service and operating temperature, including trace removal for ultra-purification applications, are taken into consideration.

Multiple problems can be addressed in a single vessel. For the removal of sulfur, chloride species and other impurities from refining or petrochemical feedstreams, our trademark layered bed design technology matches our diverse line of purification absorbents and catalysts to the specific impurity type, concentration, temperature and other relevant purification conditions.
