Grasys has set up a high-tech plant in Dubna (Moscow Region), the first in Russia and the CIS to manufacture hollow fibre gas separation membranes and membrane cartridges which are widely used in various industries, including the oil and gas, iron and steel, food and many others.
Hydrogen concentration (up to 90–99.9%). Adjustment of H₂/CO components in synthesis gas.
Impoverishment of CO₂, hydrogen sulfide. Drying of natural and other gases.
Helium impoverishment in product gas. Generating a helium-rich flow. Generating helium concentrate.
Reduction in heavy hydrocarbons (С3+), hydrogen sulfide, CO2, mercaptans in gas, drying.
Nitrogen content reduction in gas twice as much and more without using cryogenic solutions.
Nitrogen generation (with a purity of up to 99.9%) from atmospheric air.
Biogas upgrading to biomethane (removal of CO₂ and other impurities).
Grasys technology enables process challenges to be efficiently addressed through the use of different selective layers and a variety of fibre geometries.
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.
