Membranes for nitrogen content reduction in natural gas buy from the research and production company Grasys

Membranes for Nitrogen Content Reduction in Natural Gas

Nitrogen content reduction in natural and other hydrocarbon gases without using cryogenic solutions. In a single-stage design, nitrogen content is reduced twice as much. Complex configurations with recycles are most commonly used (to reduce the target component losses). Membranes with a reverse permeability sequence are used with permeate as target stream.

Diameter, " 12

Feed gas pressure, MPa up to 8.0

Membrane pressure drop, MPa up to 6.0

Feed gas temperature, °С ranging from 20 to 70

The principle of membrane separation of a gas mixture is based on the different penetration rates of its components through a polymeric membrane due to the differential partial pressures of the gas on either side of the membrane.

Membrane gas separation technology is widely used throughout the world to extract nitrogen from air, extract hydrogen from hydrogen-bearing gas mixtures, and extract carbon dioxide and water from natural gas.
