Scientists have for a long time been researching and testing various methods of gas separation. There have been several successful breakthroughs. Among them is the use of an artificial membrane to act as a sieve for various particles in the air. This serves to increase the velocity of the more concentrated particles left, hence actively separating the gases. This is known as nitrogen membrane system in some circles and nitrogen separation in others.
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.
It is this differential pressure on either side that causes the gas to separate. As the natural gas is passed through the entry pipe into the compartment laced with the artificial membrane, oxygen particles which are lighter diffuse outwards, leaving higher concentrated amount of nitrogen. As the pressure rises, so does the velocity of these particles. This causes the pure nitrogen to be pushed out of the exit. From here, it is collected for storage and further purification.
This procedure of this Membrane system has been found to have some advantages over other similar systems. This include having both cost and energy savings of up to 50%. This is in comparison to other cylinders, liquefied, adsorption and cryogenic systems. This savings are mainly attributed to the simplicity of this systems.
Some of the shortcomings of the systems include their limited capacity of production. It is very rare to find these systems being used in mass production of nitrogen gas. The simplicity of this system is thought to be the cause of this. At high air intake rates, the system is unable to produce relatively pure nitrogen as more oxygen particles pass along with the nitrogen.
There exist other nitrogen separation systems which also have the same capabilities as these. They include Pressure Swing Adsorption Generators. These have the ability to produce the same level of purity as the membrane ones. There are also on site cryogenic systems which are praised for their high volume of production and reduced costs. Portable versions of these systems are also in use.
The systems have been adopted in various industries and for many uses. These include in food and beverage preservation, filling up aircraft and motor vehicle tires, as an antioxidant in electronics, a cooling agent in glass industry. In the petroleum industry, it is used as a cleaning agent and to create an inert environment to prevent explosions of flammable petroleum.
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.
