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.

The advantage of onsite MVS-Carbotech CMS N2 generator:

  1. It allows you to generate nitrogen privately.
  2. It reduces operational costs.
  3. Fully automatic machines allow you to save labor cost
  4. Easy maintenance
  5. Safe to operate.
  6. It occupies less space because it is skid-mounted.

Applications of MVS-Carbotech CMS Nitrogen generators:

  1. To prevent reactions and explosions in chemical plants
  2. To prevent chemical oxidation
  3. To prevent explosions of chemical tankers
  4. As an atmospheric gas for rubber vulcanization
  5. As an atmospheric gas for melt spinning system for synthetic fibers
  6. As an atmospheric gas for nitrogen type reflow furnace
  7. As an atmospheric gas for storing products
  8. As an atmospheric gas for storing packaged foods
  9. As an atmospheric gas for heat-treatment
  10. As a carrier gas for drying or recovering solvents
  11. As a transfer gas for flammable or explosive items
  12. As a supporting gas for laser processing
  13. To control the atmospherefor storage of fruits and vegetables

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.
