Purification Series Adsorbents

“Purification” can refer to different kind of impurities polishing. For an easier segmentation and accessibility, dedicated webpages are available addressing specific contaminants purification such as drying, sulfur, arsine, mercury, fluoride and chloride removal. This webpage will focus mainly on the removal of polar compounds (oxygenates, nitrogen and sulfur) as well as TBC (Ter-Butyl-Catechol: polymerization inhibitor).

These contaminants have to be removed mainly due to their toxicity, avoiding corrosion issues, freezing concerns (downstream of the cold boxes used for liquefaction), preventing downstream catalysts deactivation and also meeting final products high purity level. These products are widely used in different markets such as refining, petrochemicals, chemicals, natural gas, air and industrial gas.

Drying Series Adsorbents

Water removal applications are widely encountered in the industry sector. Activated alumina and molecular sieves stand at the forefront of the several different materials available on the market.


Sulfur Removal Adsorbents for Oil, Gas & Petrochemicals

Hydrogen sulfide (H₂S), COS, mercaptans or sulfides are common contaminants that must be removed from various gases and liquids such as natural gas, NGLs, LPGs, cracked gases, olefins or biogas.


Arsine Removal Adsorbents

The poisonous effects of arsine and other metal hydrides on hydrogenation and polymerization catalysts is well documented. By far the most common, arsine can seriously deactivate the high-activity Ziegler Natta, metallocene and noble metal catalysts used for processing cracked light ends.


Mercury Removal Adsorbents

Mercury removal from hydrocarbons is crucial due to HSE-related issues, corrosion problems and downstream catalyst poisoning.
