The Uses of Nitrogen Gas Generators

Nitrogen Generators / Nitrogen Gas Generation has a wide variety of applications, including serving as an inert replacement for air where oxidation is undesirable;

• To preserve the freshness of packaged or bulk foods (by delaying rancidity and other forms of oxidative damage) - potato chips, nuts, snack foods and packaged salads.
• To preserve the freshness of wine (by delaying rancidity and other forms of oxidative damage)
• On top of liquid explosives as a safety measure - paints and solvents
• The production of electronic parts such as transistors, diodes and integrated circuits (prevents oxygen and moisture)
• Dried and pressurized, as a dielectric gas for high voltage equipment 
• Use in military aircraft fuel systems to reduce fire hazard.

Nitrogen is commonly used during sample preparation procedures for chemical analysis in laboratories. Specifically, it is used as a means of concentrating and reducing the volume of liquid samples. Directing a pressurized stream of nitrogen gas perpendicular to the surface of the liquid allows the solvent to evaporate while leaving the solute(s) and un-evaporated solvent behind.

A nitrogen generator has many practical and cost saving applications that will not only improve your products but will increase your overall profits.

How an Oxygen Gas Generator Works

Oxygen gas generators, also known as oxygen concentrators, are machine devices designed to provide high concentrations of oxygen to those undergoing therapy treatments. They can also be used in industrial environments. Another type of generator that uses a canister container can be found on airplanes, space stations and submarines. The type used for oxygen therapy recycles oxygen from the air in the environment. The smaller canister containers use sodium chlorate pellets to create oxygen. When the sodium chlorate is burned, it naturally gives off oxygen. An igniter switch is used to start this combustion process.

Another material capable of giving off oxygen when it is burned is potassium chlorate. The use of chemical conversion processes as generators, as opposed to just storing oxygen inside tanks is a more efficient mode of delivery capable of generating at least five times more oxygen than a storage tank device. Depending on the desired use, both concentrators and conversion devices are preferred to the oxygen tank apparatus.

Oxygen gas generators concentrate the oxygen available in the environment by using a filtration system that separates air components and leverages their individual physical properties. These devices are made up of a compressor mechanism, sieves or filters and a concentrator. The machine draws the air in through a series of filters which lead to a column designed to separate the different chemicals in the air. This column contains a substance called zeolite that grabs onto the nitrogen particles in the air while allowing oxygen molecules to pass through.

A second column space inside the generator works to blow back against the zeolite filter and send its nitrogen particles back into the air. The second column also works to receive some of the oxygen molecules that pass through the first column. Some of these molecules are also blown back through the first column. In effect, these two columns cycle through this process over and over again. From there a reservoir chamber receives the concentrated oxygen molecules and sends them through a flow control system that determines how much oxygen a patient receives.

What Is a Gas Generator?

A gas generator is a device which burns gas to generate electricity. Gas generators can be seen in use in a number of different settings, and they are readily available around the world. Many hardware and home supply stores stock small gas generators, and larger versions are available from specialty companies and electricians who specialize in generator installation, maintenance, and repair. It is also possible to build a custom gas generator for a highly specialized application, such as supplying stable power to a server farm in a blackout.

The fuel burned in a gas generator varies. Gasoline is one option, as are propane, natural gas, and other gases, which may be derived from petroleum, created in a biogas generator, or produced as part of alternative fuel production. Biodiesel, for example, can be used as a fuel source for some gas generators.

The generator uses the fuel to generate mechanical energy which is converted into electrical energy. The amount of energy produced by the generator depends on the components and the amount of fuel used. Size can also be a limiting factor; the smaller the generator, the less energy it is capable of producing on demand.

One common use for a gas powered generator is as a backup power source. When the electrical grid is not functioning or not accessible, a gas generator can used to supply all or part of the power needs for a structure or community. Many businesses regard gas generators as a necessary business expense, as they need a reliable source of power in the event of an outage in order to remain operational. This is especially true in businesses which handle perishables or rely on computer systems to function.

A gas generator can also be used as a primary power source in regions where electricity is not available or when people want to live off the grid. Some other uses include in fieldwork, where the generator is used to bring power to the field, and on tractor trailers which need electricity for cooling or other functions.

A basic portable gas generator like those available in many hardware stores can be enough to supply the power needs of a household. For a business, community, or large building, however, a custom system needs to be installed to meet power needs, especially if people want features like uninterrupted power supplies. An electrician can assess the given needs and recommend a product or system which can be used to provide primary or backup power.
