Air Membrane Type Nitrogen Generator / Industrial Nitrogen Membrane Unit
Membrane Nitrogen Generator Technical Features
Nitrogen generation system uses pressure swing adsorption principles at normal temperatures, along with clean, compressed air as the raw material, and a carbon molecular sieve as the adsorbent, the adsorbent we use from Japan & German guarantee the working life over 20 years,
Due to oxygen and nitrogen different sieves, CMS under pressure adsorbing the oxygen pass through nitrogen, by pneumatic valve control PLC system to get required nitrogen purity .
Membrane Nitrogen Generator Application:
1. Metallurgy: For anneal protection, agglomeration protection, nitrogen, furnace washing and blowing
etc. Used in fields such as metal heating treatment, powder metallurgy, magnetic material, copper
process,
2. Chemical and new material industries: For chemical material gas, pipeline blowing, gas replacement,
gas protection, product transport, etc. Used in fields such as chemical ,urethane elastic fiber, rubber,
plastic, tire, polyurethane, biological technology, intermediate, etc.
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.
