Gas separation

Efficient gas separation in PSA and VPSA systems

Efficient gas separation is becoming increasingly important in many technical areas. PSA and VPSA plants play a major role in this. In these plants, technical zeolites are used as molecular sieves or carbon molecular sieves.

Zeolites and molecular sieves for gas separation

A number of different zeolites and molecular sieves are available for the separation of technical and biogenic gas streams. Thanks to their specific characteristics, you can use precisely the right product, depending on your own requirements, to enable the best possible result in your PSA or VPSA plant. We are more than happy to advise you here!

Carbon molecular sieves for the separation of technical and biogenic gases

NECA|cms® carbon molecular sieves are characterized by a precisely defined micro-pore system, with long-lasting and reliable performance. Due to their high hardness, dust and abrasion are minimized during operation. Various quality classes open up a wide range of possible uses for the user.

  • Separation and production of nitrogen
  • Biogas upgrade (CO2 depletion)

In addition to delivery with NECA|cms®, NECATEC always offers you comprehensive technical advice and a professional exchange service.


Carbon molecular sieves with different performance parameters

Zeolite molecular sieves for the separation and drying of technical and biogenic gases

NECA|zeo® are synthetically produced microporous solids, alkaline, potassium-based or sodium-based. They can be used effectively in virtually any application due to their specific geometric shapes and homogeneous pore structure available in different sizes.

  • Separation and extraction of oxygen
  • Separation and extraction of methane
  • Removal of odorants
  • Removal of mercaptans
  • Drying of gases
