PSA Nitrogen Plants

We are manufacturing state of Art Nitrogen Plants, PSA Nitrogen Plants and PSA Nitrogen Gas Plants in technical collaboration with carbo Tech, Germany. These work on pressure swing adsorption principle. We provide variety of PSA nitrogen plants, nitrogen gas generator, Hydrogen Generation by water electrolysis, Water electrolysis based Hydrogen Plants, Hydrogen Generation Plant by water electrolysis, refineries, water electrolysis based hydrogen plants and chemical plants, oil and gas platforms, metal-treatment, tankers and storage tanks, pipelines etc.

Salient Features of PSA Nitrogen Plants:

• Capacities upto 2000 NM3/hr.
• No fuel is required
• Purity upto 99.999% is easily achievable
• Low Capital & running cost
• Start up time of only 15 minutes

Process:
Nitrogen generation plant based on the PSA process consist of two adsorbers filled with carbon molecular sleve (CMS). Compressed and purified air is passes through the absorbers. Mainly oxygen is absorbed on the carbon molecular sleve and nitrogen enriched gas is leaving the absorber. The oxygen concentration can be reduced to almost all required levels. During adsorption in one adsorber the second adsorber is totally regenerated just by depressurization to ambient pressure. The oxygen enriched off gas is vented. After about one minute adsorption in one adsorber the process controller is switching over to the second adsorber.


Material:
Carbon molecular sieves:
We use material from carbotech who has pioneered the scale - up of the production of narrow pored carbon molecular sieves to an industrial level. In one multi-step process on ultra-fine pore structure is formed in the molecular sieves pollets. This structure facilitates easy separation of different sized oxygen and nitrogen molecules. CMS is the crucial element of any PSA plant utilizing the BF-Process. The characterstics of CMS are unique. It is highly resilient towards long term pressure swing usage. Moreover, the excellent auto regenerative characterstic of the sleve leads to many years of high quality nitrogen production. Hence one CMS charge lasts as long as the PSA plant. This makes it a safe long terms investment.

Capacity & Sizes:
It is available in capacities upto 2000 Nm3/hr. and higher capacities are available on request.



Purities:
Nitrogen is available upto 99.9999% purity. Various modle are available for different kind of applications.

Models:
Standard purity:
This is most popular model and produce gas upto 99.9% without any purification system. Most economical purity is 97.5% to 99.5%

DX Model:
In case higher purities are requried like 99.999 % and additional deoxo purification systems is requried. There are two types :

Palladium based purification system:
In this after PSA plant a deaxo tower is added in which hydrogen reacts with oxygen and thus removes oxygen from Nitrogen. Moisture formed is removed in downstream gas dryer. Following is the composition of gas.
Nitrogen: 99.999%
Oxygen: in ppm level
Hydrozen: 0.5% min. or more if required
Dew point: -( 60 ) deg. or better

Copper based deoxo purification system:
However, in case, both hydrozen and oxygen are not required. A copper deoxo based system is used to eliminate both hydrogen and oxygen.
Nitrogen: 99.999%
Oxygen: ppm level
Hydrogen: Nill to ppm level

Hydrogen source ( ammonia cracker unit )
Note: In both the above cases, hydrogen can be sourced from ammonia cracker unit which can be supplied as part of plant.

Ultra high purity model:
In this type, purity of 99.9999% is directly available from PSA module without deoxo by use of different technology/material & longer time cycle.
Advantages are:

• Higher purity without deoxo system.
• Most useful where hydrogen/ammonia is not easily available.
• Most economical upto 100 Nm 3/hr.

We manufacture Membrane Based Nitrogen Generators for low purity applications like food pakaging, jet mills. chemical tanks and pipelines etc.


Ultra high purity model:
In this type, purity of 99.9999% is directly available from PSA module without deoxo by use of different technology/material & longer time cycle.

• Higher purity without deoxo system.
• Most useful where hydrogen/ammonia is not easily available.
• Most economical upto 100 Nm 3/hr.

Applications
PSA nitrogen for these and many other applications.

Refineries and chemical plants :
Nitrogen generated by PSA plants is being used with an upward tendency for inertizing in a variety of processes in the chemical and petro chemical industries paricularly to avoid oxidations reactions and even combustion and explosions.

Bear, wine and juices:
Storing, refilling and bottling of beverages such as bear, wine and fruit juices are being effected more and more frequently with nitrogen which , due to its extremely low solubility and its inert character, provides the desired neutral atmosphere. In addition PSA nitrogen, ideally in a mixture with carbon dioxide, is being used more often for dispense of beverages, especially bear.

Oil and gas platforms:
PSA - Nitrogen is used for inertizing purposes on offshore platforms. The application here is usually to displace atmospheric air to prevent fires and explosions.

Metal-treatment:
Nitrogen from PSA - plants is used either in its pure form or in a mixture with reactive gases such as hydrogen or methane for heat treatment of steel and other metallurgical products.

Storage of fruits and vegetables:
Supplying a broad public with fresh fruits and vegetables over longer periods of time is no longer possible without transportation and storage in a controoled atmosphere- one of which is nitrogen with the desired low oxygen content, produced by PSA - plants.

Electronics/Laboratory applications:
The extreme quality requirements in the production of electronic components (microchips, for example) and increasing demands in regard to modern analysis methods can in many cases be satisfied with pure nitrogen (99.999 Vol.-% e.g.) generated in PSA - plants.

Tankers and storage tanks:
Whether in tankers used to ship liquefied natural gas, oil or chemicals, or in stationary storage vessels, nitrogen is used as blanket gas and for purging. In most cases, nitrogen serves an explosion prevention function and protects against undesired reactions of oxygen with the contents of the tanks.

Food Packaging:
The shelf life of perishable foods such as bread, cheese, meat, coffee, edible oils and spices can be considerably prolonged by packing in an atmosphere of nitrogen. Nitrogen will effect niether the taste nor the flavour the foods.

Pipelines:
Service and maintenance work at oil and gas pipelines often requires nitrogen inrtization to protect the crews against fire and exposure. In many cases the nitrogen can be supplied by mobile PSA systems.
