Carbon molecular sieves

CarboTech is known across the world for innovations in the field of activated carbon. One thing to come out of our research and development work has been carbon molecular sieve (CMS) technology which is used in nitrogen production and other applications.

To obtain high-purity nitrogen, manufacturers rely on pressure swing adsorption (PSA). Compressed air is fed alternately into two containers filled with CMS which capture oxygen molecules, leaving extremely pure nitrogen which is then directed into downstream collection tanks from where it can be fed directly into the customer’s grid.

CMS are also used in these applications:

  • Biogas upgrading
  • Noble gas recovery

Robust, durable molecular sieves

CarboTech distributes products from OSAKA Gas Chemicals under exclusive arrangements in Europe, India and the Middle East. The CMSs are exceptionally hard, enabling short pressure equalisation times and high pressurisation and de-pressurisation rates. They are also great at self-regenerating, meaning they can be used for many years in nitrogen production environments.

 

Biogas upgrading with CMS

In addition to electricity, technical biogas plants also produce biomethane. In order to feed this into the natural gas grid, it must only contain a small amount of CO. Our CMS can filter out CO.

 

Innovation with its roots in Essen

And that’s not all, because CarboTech is constantly working on further applications for our CMSs in partnership with a university of applied sciences. This gets the benefit of our decades of experience. We are constantly in close contact with our customers regarding possible uses, adaptations and product design improvements. This way, we know exactly what the market needs and can supply tailor-made solutions.

Optimised processes and thorough quality control are a matter of course for us. We provide our customers with CMS sieves that are ultra-efficient and offer the very best value for money.

Your advantages of CMS at a glance: Nitrogen production

Nitrogen production Carbon molecular sieves are an important element of a PSA system (pressure swing adsorption system) to generate nitrogen. The PSA process offers its own, independent and cost-effective air separation. Overall, nitrogen has many applications in the chemical industry, e.g. for purging storage tanks, pipelines and tank trucks, for processing and storing perishable food and beverages, for inerting during heat treatment of metals and furnaces, for processing plastics and fibres, in the manufacture of flat glass, in fire protection systems, in microchip production and many other applications.

Your advantages of CMS at a glance: Biogas upgrading

Biogas upgrading The use of CMS in the upgrading of biogas is constantly evolving. For example, biogas can be upgraded to the perfect natural gas quality in a multi-bed PSA plant. This process is extremely economical and achieves excellent methane yields. It is also an excellent renewable energy source as an alternative to fossil fuels.
