Problems to address

Helium membranes

  • 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.

Hydrogen membranes

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

Natural Gas membranes

  • 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.

Biogas membranes

  • Biogas upgrading to biomethane (removal of CO2 and other impurities).

Nitrogen membranes

  • Nitrogen generation (purity up to 99.5%).
