Use of N2 Gas in Medical and Pharmaceutical Industries

Nitrogen gas has a wide variety of uses across a range of multiple industries. From food storage to electronics manufacturing to corrosion prevention, Nitrogen can be used to keep products dry and sterile, improve their durability and even provide a safer, cleaner environment for industrial workers. Another common application for Nitrogen gas is within the medical and pharmaceutical industries. These industries utilize N2 gas to reduce the presence of oxygen in situations where combustion is a major concern. This is done through a process called blanketing.

Through blanketing, the environment is made inert so that the risk of fire and/or explosions is greatly reduced or eliminated altogether. Because oxygen is a key ingredient for combustion, eliminating the presence of oxygen by displacing it with N2 gas significantly improves the safety of the manufacturing facility.

In addition to reducing or eliminating the risk of combustion, blanketing with Nitrogen can also help preserve or improve the quality of the pharmaceuticals and other medical products. Blanketing with N2 gas essentially displaces the oxygen present with Nitrogen, so there is little to no chance of oxygen's harmful side effects. Corrosion, rust, oxidation and other significant reactions can occur when oxygen is present and reacts with other materials. This can seriously alter or damage the products being handled or manufactured. In the pharmaceutical and medical industries, it is imperative that conditions for the safe handling and manufacturing of products be preserved.

Here are a couple of specific examples of nitrogen uses in the medical and pharmaceutical industries:
  1. Nitrogen is often used in the packaging of medical supplies (Nitrogen helps maintain sterility and cleanliness of the product). Nitrogen is used to purge oxygen from the packaging before it is sealed, creating an environment made of high purity N2 gas, which will also help preserve and protect the product during transport. Test kits for doctors' offices, blood supplies, specimen containers and other medical devices are some examples of items frequently packaged with N2 gas.
  2. Nitrogen is often used in the transferring of pharmaceutical products. The use of a safe, inert gas to transfer liquid or powder pharmaceutical materials is necessary, as these materials can be hazardous if improperly handled.
Nitrogen Generators are systems that safely produce high purity Nitrogen gas and are often used for medical equipment in laboratories or hospitals.  Nitrogen Generators are safer and easier to handle than high-pressure cylinders. These generators can be used to control the level of oxygen in the workspace, lab or throughout an entire facility.

Nitrogen Generators are highly efficient, as they create their own supply of nitrogen from the surrounding air. With an onsite Nitrogen Generator from leading manufacturer South-Tek Systems, your facilities manager won't have to bother with changing out expensive, high-pressure cylinders. This not only improves the safety of your facility, it reduces costs and can help your lab operate at a higher level of efficiency.

Food Storage with Nitrogen

Nitrogen can be used in manufacturing, industrial, commercial and retail applications, making it a pretty versatile gas. One of the many ways Nitrogen has benefited our lives is through its use in the food storage industry.

In the food storage and packaging industry, Nitrogen plays a critical role in preserving the product's freshness, flavor and texture.  N2 gas is a clean, dry and inert gas (which means it's very safe when handled properly) that can reduce or eliminate the presence of oxygen (which is an essential factor in the decay of organic matter).

With some exceptions, food and beverages that are purchased in grocery stores were likely packaged days or even weeks before they arrived on the shelves. In order to maintain the food's quality while in the packaging facility, and preserve its quality even after it's shipped, packaging facilities rely on optimized storing methods - which often include the use of Nitrogen gas.

Nitrogen displaces the presence of oxygen, but it can also be used in blanketing applications, which is a process in which the interior of the packaging is padded with Nitrogen gas to prevent crushed and broken food products like crackers, chips and other more fragile items.

Produce can also be effectively preserved by using nitrogen in packaging facilities. Nitrogen can help create an atmosphere in which levels of humidity and oxygen are controlled to decelerate the ripening process in fruits and vegetables. Apples, pears, bananas, tomatoes, and so on can have significantly different flavors and textures when they are overripe. By using Nitrogen to alter the atmospheric conditions in a food processing or storing plant, these items can have a much longer shelf life and, more importantly, they can maintain their good, fresh taste for consumers to enjoy.

One of the more common and most cost effective methods for introducing Nitrogen in such applications is to install a Nitrogen Generator from South-Tek Systems. Nitrogen Generators create high purity Nitrogen gas from the air we breathe, which means the supply will never run out and facility operators can free themselves from the tedious and hazardous task of storing high-pressure N2 gas storage tanks.

Biofuel Storage with Nitrogen

In recent years, the biofuel industry has seen tremendous growth. In 2011, Biofuels Digest reported a growing demand for alternative fuels, as evidenced by the results of the 2011 Bioenergy Business Outlook Survey. Not only did the survey reveal a growing demand for the biofuels market, it found that further growth is expected by 85 percent of industry executives (Source: Source: Biofuels industry increasingly bullish about 2011; cite "rising demand for alternative fuels" in Business Outlook Survey). Now more than ever, the need for safe, efficient biofuel storage is rising.

As the production of alternative fuels becomes more widespread, facilities that handle, transport and store these fuels will need to optimize their methods to ensure safety. Methanol, a key component of biofuel, can be extremely hazardous if improperly stored. When stored in tanks, for instance, methanol has a tendency to form flammable vapors. To ensure the safety of these storage tanks, Nitrogen is often utilized to prevent the formation of these vapors. By introducing Nitrogen into the extra space in methanol tanks, the presence of oxygen can be effectively eliminated. This process is known as atmosphere blanketing, or tank blanketing.

The process of tank blanketing using a dry, inert gas such as Nitrogen, can effectively reduce the risk of combustion, corrosion and other dangerous effects. Oxygen is an essential factor in combustion as well as oxidization, which can lead to corrosion. By eliminating the presence of oxygen, these problems are far less likely to occur.

While combustion is obviously a major safety concern, oxidization and corrosion can also cause negative effects. The presence of oxygen in biodiesel and methanol tanks can negatively affect the quality of the fuels. By practicing tank blanketing techniques, the quality of the biofuels can be preserved. Get more details on Biofuel Storage Tank Purging with Nitrogen Gas.

South-Tek Systems can further aid in a biofuel storage facility's operations by installing a Nitrogen Generator, which produces high purity Nitrogen from the surrounding air. Having an on-site Nitrogen Generator eliminates the need for purchasing, storing and handling high pressure nitrogen cylinders. This can be a cost effective alternative to having stored Nitrogen. With a Nitrogen Generator, facilities that rely on N2 gas for their essential operations can benefit from having a never-ending supply on demand while maintaining a safe, inert atmosphere for blanketing applications.

Exhaust Dilution with Nitrogen Gas

Exhaust dilution is an important process used extensively in manufacturing and industrial applications. The process works by emitting gas particles from mechanical engines and diluting phase pneumatic conveying of materials through a system of pipes.  This process cools the surrounding atmosphere and eliminates the presence of oxygen, alleviating a huge safety concern.

Without such a process in place, excess heat and dust can build up and oxygen can react with hazardous materials causing imbalances in pressure and even explosions. Additionally, the presence of oxygen can create unwanted damage through oxidization, a reaction that occurs when condensation forms along the mechanical equipment.

By using Nitrogen gas in an exhaust dilution process, the presence of oxygen can be eliminated, preventing oxidization and serious safety hazards. Because Nitrogen is a clean, dry and inert gas, it can help diffuse or dilute the materials found in a pneumatic conveying system without the unwanted presence of oxygen. Nitrogen is commonly used in pneumatic conveying systems to help transport materials, particularly closed-loop systems. In these systems, the gas is recycled and conserved as the transport medium.

Safety is a major concern when it comes to the operation of a pneumatic convey system. Some types of materials that are transported through these systems are explosive, especially in high concentrations. By using an inert gas such as Nitrogen, a pneumatic conveying system can function at the optimal level of safety. Through exhaust dilution with Nitrogen, these dangerous materials can be effectively transported and your facility and equipment can continue to operate successfully.

To learn more about Nitrogen for exhaust dilution, as well as other common industrial applications for Nitrogen, contact South-Tek Systems - a leading provider of Nitrogen Generators.

Other industrial applications for nitrogen include aerospace manufacturing, burst testing, nanolabs and there are many more. No matter what type of facility you run, it is likely that Nitrogen can help your business run more safely and efficiently. Call us at 888-526-6284 to learn more.
