Understanding Liquid Helium(HE)

Liquid Helium is non-corrosive, odorless, colorless, inert, inflammable, and extremely cold. Helium does not react with other elements under ordinary conditions. As helium is non-corrosive, special construction materials are not required. However, construction materials should only be used if they are suitable to be used with the extremely low temperatures of liquid helium.

Nitrogen for the blanketing process is used in numerous industries to safeguard them from explosion, fires, and the damage of the products while production, storing, and transportation. Using nitrogen for blanketing enables the user to reduce operating costs and improve safety.

What is Nitrogen blanketing?

Nitrogen blanketing is a process in which the gaseous form of nitrogen is injected into a moderately filled or empty storage tank or container. The presence of N2 will prevent the outbreak of chemical reactions that may cause oxidation, explosion or any other effect.

Petrochemical Plant

For blanketing process, nitrogen can be produced in through:

  1. Pressure Swing Adsorption technology
  2. Membrane gas separation technology


Pressure Swing Adsorption method uses numerous adsorption rates of several gases when passed through an adsorbent material. The adsorbent material separates gaseous mixture depending on its chemical properties and unique physical properties through a two-step process i.e. adsorption and desorption.

PSA N2 generators can manufacture N2 with purity higher than 99.9995%.


The membrane gas generation technology is based on a different rate of permeation of air components through the hollow fiber membrane.

When membrane nitrogen generators are used to produce nitrogen for padding tanks, semi-permeable membranes are utilized to separate inflowing air into its prominent components. The nitrogen extracted from the generator can be then injected into the chemical tanks.

Applications requiring Nitrogen blanketing

Industries use nitrogen both, during storage and transfer. Nitrogen blanketing is employed in:

  • Storages tanks
  • Chemical tankers
  • Airplanes
  • Transformers

MVS-Carbotech CMS for PSA Generators

Carbon Molecular Sieves (CMS) are the most pivotal element ofthe Pressure Swing Adsorption (PSA) technology nitrogen gas generator. Pressure Swing Adsorption nitrogen generators utilize adsorptive materials as a carbon molecular sieve to separate nitrogen molecules from compressed air. CMS adsorbs carbon dioxide, oxygen, moisture and other things in a short time and compressed nitrogen is available at the outlet. As the pressure is decreased to the vacuum or atmospheric level, CMS, having adsorbed oxygen and other molecules desorbs them and get regenerate.


After both the operations take place alternately between the adsorption columns, an uninterrupted supply of nitrogen is available from the air.

MVS Engineering is a leader in manufacturing and exporting on-site gas generators. The company is a primary licensee of PSA technology from Carbotech Germany. Carbotech GmbH Germany is the inventor of CMS used for nitrogen recovery in PSA type nitrogen generation systems.

Choose a Reliable Nitrogen Generator Exporter

Onsite nitrogen gas generation is beneficial to a wide range of applications like food and beverage manufacturing, electronic and pharmaceutical industry. Generating gas onsite provides three distinct advantages over using nitrogen in tanks and bottles. These three advantages are no wait time, guaranteed purity and lower overall cost.


How is nitrogen generated?

Nitrogen is actually not created in the nitrogen generators. These generators extract the already present nitrogen from the air and work on it by eliminating other molecules.The air around us has 21 percent oxygen and 78 percent nitrogenand a mixture of some other molecules like argon, water and carbon dioxide present in it.

MVS, largest Nitrogen gas generator exporter has nitrogen generators that work on two methods for removing extra molecules. The first method is to filter out unwanted molecules and it is called as Pressure Swing Adsorption (PSA) technology. The air is pulled through the intake valve and sent through the carbon molecular sieve (CMS). These sieves have pores around the surface that fit the size of oxygen molecules. As O2 molecules are smaller than nitrogen molecules, they pass through the CMS and the larger molecules of nitrogen remain on the top of the CMS.

Another technology in the nitrogen generator is membrane technology. The membranes are a group of small, hollow polymer fibers with small pores across the surface. As oxygen molecules are smaller than those of nitrogen, it passes through these pores leaving nitrogen in the gas stream. The user can produce 99.5 percent of pure nitrogen using this technology.

Carbon Molecular Sieves in PSA Generators

Nitrogen Generators are manufactured using two technologies, namely Membrane technology and Pressure Swing Adsorption (PSA) technology. One of the core technologies is PSA, using Carbon Molecular Sieve (CMS) adsorbent. The PSA process utilizing CMS is an extremely productive way of producing high purity nitrogen gas from compressed air.

What are CMS and PSA?


Pressure Swing Adsorption, an air separation technique, allows the segregation of the mixture of gases into its individual components by using a solid medium, i.e. CMS adsorbs some proportion of the gas mixture under pressure.


Basically, CMS is the bed of small carbon particles. When a nitrogen purification column packed with carbon molecular sieve is pressurized with atmospheric air (that mainly consists of oxygen, argon, and nitrogen), moisture and oxygen is adsorbed by the carbon bead but allows Nitrogen to pass on. This happens because of the mill micron size of the nitrogen molecules. The CMS pores are of the perfect size to let oxygen enter and adsorb but the nitrogen molecules are too big and therefore pass through the purification column.

The two-stage cycle of the PSA process;

  1. The Adsorption stage-

This is the stage where moisture, oxygen and carbon dioxide molecules present in compressed air are adsorbed onto the porous structure of the carbon molecular sieve whereas Nitrogen molecules pass through the column and goes into the storage vessel.

  1. The Regeneration Stage-

This is the stage where the pressure normalizes via quick de-pressurization and the adsorbed molecules are released to the atmosphere. A constant temperature is required in this process that as close to an ambient.

MVS Engineering Pvt. Ltd. manufactures and exports PSA generators that are designed using German technology from CarboTech AC GmbH. The industries where MVS PSA Nitrogen generators are widely used for Fuel Tank Inertization, Tire filling, Autoclaves, Furnaces, Blanketing for many industries, Metal processes, Fire prevention, Laboratories, Oil Cargo ships and oil tankers, Flex printing, Oil & Gas and Petrochemicals and Offshore Platforms & FPSOs.

Industries that use Nitrogen Gas for their process

Nitrogen, which makes up around 78% of the air that we breathe, is tasteless, colorless and odorless. It is one important element in proteins, and it is found in almost all living systems. N2 is found in organic materials, fertilizers, foods, poisons, and explosives. Also, it is used in a number of industries because of its noncombustible and nontoxic properties.

For industrial use, on-site MVS Nitrogen generators are the most affordable and efficient solution. The company customizes the system that is just perfect for you and your industrial requirements. No matter which type of industry you deal with, an on-premises generator is beating the drum for being an excellent choice for return on investment and offering the gas quickly.


Industries that use Nitrogen Gas for their process

There is a wide range of industries that use Nitrogen in their process. Some of those industries are:

  1. Tyre inflation industry– N2 is extremely beneficial when it is filled in tires. N2 filled tires give them an extended life and also provide a better mileage to the vehicles.
  2. Food packaging industry- Packaged food is prone to oxidation because of oxygen. N2eliminates the oxygen from the package so the food can last longer. In the packet of chips and some other delicate food items, it acts as a cushion and safeguards it from breaking.
  3. Electronic industry– N2 is used for brazing/soldering in this industry. It minimizes the tension on the surface and provides a cleaner break-away from the solder site.
  4. Pharmaceutical industry– There is hardly any major drugs that do not consist of nitrogen, including antibiotics. It is also used as an anesthesia in its nitrous oxide form.
  5. Pollution controlling- Before discarding the waste liquids into, nitrogen is used to remove the VOCs from them.
  6. Chemical plants– N2 displaces oxygen and prevents oxidation in process. Also, it prevents explosion in process tanks or chemical storage tanks due to presence of oxygen.
  7. Bulb industry- N2 serves as a cheaper alternative to argon.

Nitrogen Gas Generator for TyreIndustry

The atmosphere surrounded us is 78% nitrogen, 21% oxygen and 1% other gasses plus water in different amount depending on the location it is at.


Use of Nitrogen in Tyre Inflation:

Aeronautic industry and Formula One (F1) have sent forward and promoted the use of nitrogen gas for mainstream vehicles. Therefore, more of nitrogen gas generator exporters are coming up in the market with efficient nitrogen generators that can be used in motorcycle repair shops.

Benefits of Inflating nitrogen in tires:

  • Increased tyre life. Tyres’ life usually deteriorates due to lack of attention to tyre pressure and vehicle maintenance. Inflating N2 in tires result in longer tyre life.
  • Nitrogen molecules are larger than oxygen molecules, therefore, it cannot get out through the valves or pores or from the place where tire connects with the rim.
  • N2 is a dry gas and does not contain humidity so the tyre does not get internally rust.
  • Reduces carbon dioxide emission.

MVS Engineering Pvt. Ltd. is a leading nitrogen gas generator exporter who provides the best PSA & Membrane Technology based on-site gas generators for tyre and other industries that require nitrogen.
