Refinery, Petrochemical and Gas facility operators face the challenge of solving feedstock contamination problems. Adsorption is the preferred separation technology for the removal of trace contaminants from gas and liquid streams.
The removal of undesirable impurities in modern industrial processes is critical to assure the protection of the environment, to protect downstream catalyst s, and to avoid costly unplanned shutdowns. The use of dedicated adsorbents helps operators to achieve specifications for improving their operations, upgrading the quality of their products or minimizing pollution.
Continuous industrial growth and market evolution has permitted Axens to become a recognized world leader in the supply of adsorbent products. Our extensive range of adsorbents is based on over 60 years of engineering and manufacturing of Activated Aluminas, molecular sieves and Guard-Bed materials. These adsorbents efficiently respond to every type of drying and purification requirement to serve the refining, petrochemical, gas, alternative fuels and water treatment industries. This unique combination allows Axens to be a single-source provider offering solutions that are an amalgamation of technologies, products and technical services. We are able to respond rapidly and efficiently to customer needs.
We have grouped together the Axens Adsorbents under three trade names for a complete and unique offer: AxSorb, AxTrap and actiguard .
Axens Adsorbents Portfolio
AxSorb: regenerative adsorbents such as molecular sieves and activated aluminas
AxTrap: non-regenerative guard-bed adsorbents
ActiGuard: aluminas product range dedicated to water treatment
AxSorb products are regenerative adsorbents such as molecular sieves and activated aluminas. They are widely used in many industries to dry the feedstock or to remove other contaminants.
The regenerated adsorbents portfolio is classified into different series:
- AxSorb Drying series: their exceptional properties ensure the highest performance and safest operating conditions for dehydration.
- AxSorb Purification series: Materials specially developed to achieve your feedstock’s specification requirements. Our products demonstrate superior adsorption capacity and outstanding stability for oxygenates and nitrogen and sulfur compounds removal.
- AxSorb Specialties: tailored characteristics and properties achieve the required performance for applications where, in addition to adsorption, catalytic and separation functions are required.
With this complete offer, Axens covers all drying and purification applications to serve the refining, petrochemical, natural gas, industrial gases and air drying markets.
The AxTrap product line comprises of guard-bed adsorbents specially designed for safe protection of catalysts, equipment and the environment. Our products feature superior capacities for Mercury, Arsine, Phosphine, Chlorine, Sulfur and Fluoride removal.
The AxTrap family consists of 5 non-regenerative adsorbent series:
AxTrap 100 series are highly efficient alumina based metal oxide materials that remove arsine and phosphine at levels a low as 1 ppb wt from gas and liquid hydrocarbon streams.
AxTrap 200 series comprises highly efficient ready-to-use trapping materials that remove mercury to levels less than 0.01 µg/Nm3 from LNG streams and less than 1 µg/l from liquid hydrocarbon streams.
AxTrap 400 series consists of unique mixed metal complexes which allow efficient removal of sulfur compounds.
AxTrap 600 series is activated alumina designed especially for the selective removal of HF and fluorinated hydrocarbons from HF alkylation plant streams.
AxTrap 800 series consists of ready-to-use promoted alumina or metal oxide adsorbents that are designed specifically for the removal of hydrogen chloride from liquid and gas streams. These adsorbents are operable over a wide range of temperatures to cover most chloride removal applications.
TEchnical AxTrap Management Services (TEAMS)
TEAMS consist of R&D, analytical, process, project, engineering experts, loading/unloading supervisors, operators training and performance evaluation professionals who work closely with clients to ensure the success of a facility’s whole life cycle from the original grass root design to the final disposal of spent material. Axens offers the Total Management Solution to deliver high performance, safe working and peace of mind for our customers. Moreover, the offer can be tailored to suit specific requirements.
The ActiGuard aluminas product range is dedicated to water treatment.
Activated alumina along with its promoted forms are the perfect choice for the adsorption of unwanted minerals and nutrients, with proven results for arsenic, fluoride, copper, zinc, lead, silica, phosphates and nitrates. It is currently used to treat potable water for municipal and household units as well as the remediation of waste streams.
