Hollow-Fibre Membrane Manufactured by Grasys

Grasys technology enables process challenges to be efficiently addressed through the use of different selective layers and a variety of fibre geometries.

Membranes (Cartridges) Manufactured by Grasys

Optimisation of different gas purification applications is achieved by using a variety of membrane parameters such as geometric dimensions, gas flow direction.

The current product range includes 2", 8" and 12" cartridges, with any type of gas supply.

Applications:

Helium

  • Helium impoverishment in product gas to meet the Customer's requirements. Simultaneously, there occurs decrease in СО₂ content, and additional gas drying;
  • Generating a helium-rich flow for further injection into formation;
  • Generating helium concentrate (40...90% mol.) that can be used as feedstock for further commercial helium production.
Helium

Hydrogen

  • Hydrogen concentration and producing up to 90-99.9% hydrogen-rich gas flow;
  • H₂/CO adjustment in synthesis gas.
Hydrogen

Natural Gas

  • Impoverishment of CO₂, hydrogen sulfide;
  • Drying of natural and other gases (water dew point varying from -10°С and below);
  • Reducing inert gases concentration;
  • Increasing methane content in colliery gas.
