The Uses Of Nitrogen Membrane Systems

By Janine Hughes


Gas separating procedures have been a key concern for scientists. After a lot of resources - monetary, financial and otherwise, were spent of research, several systems have been developed with varying success levels. Among these is the Nitrogen Membrane System which uses an artificial membrane to separate the gas and create pressure difference to enable flow of the needed gas.

These systems comprise a general system of gaseous separators known as nitrogen separators. They are of various types and the most common are those that make use of membranes in their separation. The material making up the membrane is crucial to the optimal operation of the system. Scientists have discovered that those with higher fibre levels were best suited for the job, since they were observed to keep the pressure difference higher for longer periods.

The systems operate on the basis of difference in pressure on either side of the membrane. Natural air is allowed to flow through the entry tube. The lighter oxygen particles pass through the membrane and therefore leave a higher concentration of the gas. This high concentration causes their velocity to increase and hence it pushes out through the exit. It is then directed to storage and further purification if need be.

There are other systems that do the same work of nitrogen separation. These include cylinder and adsorption systems, and cryogenic systems. However the membrane method has been found to have several advantages which make it preferable. These include cost savings. The particular system has been found to save on costs by up to 50%. It is also very energy efficient. These advantages have been found to stem from the core simplicity of this system.

Membrane systems also have their shortcomings. They have a limited volume by which they can produce. These systems are rarely used on large scale due to this limitation. The level of purity of this gas is another limitation. This systems do not have the capacity to produce totally pure nitrogen and especially at higher air flow rates.

There are other systems which try to match up to the nitrogen generators. These include Pressure Swing Adsorption Generators. Which are lauded for the high percentage of purity of this gas produced and reduced cost. There are other on site cryogenic systems which have high purity levels and high volume of production. Other portable systems are also available.

The applications of these systems have traversed across various industries and industries. For example in the food production, it is used to produce preservative. The gas produced can be used to fill up tires in motor vehicles and aircraft. It also has several uses in petroleum industries where it is used for cleaning as well as prevents explosions and fires since it is inert.

The systems have shown a lot of promise despite their shortcomings. They have been used to build resources, products and applications in use in various industries. The continuous research and upgrades can only make them better for more efficient production.
