C₄ Isomerization

C₄ isomerization is a process allowing to restore the thermodynamic equilibrium (iC₄/nC₄) in a C₄ paraffinic cut. Integrated with an alkylation unit, this process allows to provide the missing isobutane to the alkylation reaction.

Isomerization Catalysts

Chlorinated alumina ATIS 1L is the catalyst of choice thanks to its high activity permitting operation at lower reactor temperatures that enable higher iC4/nC4 equilibrium and favor superior yields.

Chlorinated alumina ATIS-2L is the catalyst of choice thanks to its high activity permitting operation at lower reactor temperatures that enable higher product RON and favor superior yields

Adsorbents

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.

Adsorbents

Mercury Removal Adsorbents

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

Adsorbents

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.

Adsorbents

Chloride Removal Adsorbents

Chloride is important in both catalytic reforming and isomerization as it helps to maintain catalytic activity over time. However, as chloride is continuously fed into these units, it also has to exit.

Adsorbents

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.
