Adjustable Membrane Air Separation Medical 100nm3 Nitrogen Generator

Adjustable Membrane Nitrogen Generator For Medical And Chemistry

Nitrogen separation

At the heart of the Nitrogen Membrane separation technology are polymeric membrane materials that allow for the rapid passage of one gas while minimizing the passage of another when applying pressure gradient across the membrane. Membrane materials are formed into hollow fibers to provide high surface area for high bolometric gas processing rates.

Selective Permeability

Nitrogen membranes separate gases by the principle of selective permeation across the membranes wall.

For nitrogen polymeric membranes, the rate of permeation of each gas is determined by its solubility in the nitrogen membrane material, and the rate of diffusion through the molecular free volume in the

nitrogen membrane wall. Gases that exhibit high solubility in the nitrogen membranes, and gases that are small in molecular size, permeate faster than larger, less soluble gases.

Fast Gases and Slow Gases

"Fast" gases permeate through the nitrogen membrane wall more readily than "slow" gases, thus separating the original gas mixture into two streams. The purity of the desired streams can be adjusted by changing the operating conditions.

The ability of a nitrogen membranes to separate two gases is determined by their "selectivity", the ratio

of permeabilities of the two gases. The higher the selectivity, the more efficient the separation and less

energy is needed to run the system.

Compared with other on-site gas production methods, membrane air separation nitrogen Gas Generator and oxygen enrichment equipment has the following characteristics:

1). Advanced technology, is the latest technology of normal temperature air separation;

2). No noise, completely static operation, meet the requirements of environmental protection;

3). No moving parts, less equipment maintenance;
