Gastek Engineering Private Limited

we are manufacturing state of Art Nitrogen Plants, PSA Nitrogen Plants and MEMBRANE 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%
 
DEOXO Technology Options

We offer two distinct purification technologies to meet your specific requirements for ultra-high purity nitrogen

Palladium Based Purification System

In this system, a deoxo tower is added after the PSA plant where hydrogen reacts with oxygen, effectively removing oxygen from the nitrogen stream. The moisture formed during this reaction is removed in a downstream gas dryer, resulting in ultra-high purity nitrogen.

Output Gas Composition:

• Nitrogen: 99.999%
• Oxygen: ppm level
• Hydrogen: 0.5% min. or more if required
• Dew point: -60°C or better

Copper Based Deoxo Purification System

When both hydrogen and oxygen are undesirable in the final gas stream, our copper deoxo based system provides an excellent solution. This technology effectively eliminates both hydrogen and oxygen, delivering ultra-high purity nitrogen without residual hydrogen.

Output Gas Composition:

• Nitrogen: 99.999%
• Oxygen: ppm level
• Hydrogen: Nil to ppm level
• Dew point: -60°C or better
