Nitrogen Plants

Creative OZ-Air (I) Pvt Ltd Creative OZ-Air (I) Pvt Ltd Creative OZ-Air (I) Pvt Ltd
We design, develop and manufacture a stellar range of nitrogen plants. Designed to be compact and sturdy, these nitrogen plants are highly efficient and deliver high levels of performance at all times. The nitrogen plants require low levels of maintenance and can be custom developed as per the needs and specifications of our customers.
  • Capacities - 1 to 150 Nm³/hr.
  • Output Pressure - 5.0 - 6.0 kg / Cm²
  • Purity - 50% to 99.999%
  • Economics - Cylinder - Rs. 12-15/ per M³O2
  • Generator - Rs. 3-4/- per M³
Nitrogen Generators (P.S.A. Based)
We design and manufacture a superior range of nitrogen generators with proprietary techniques that provide high efficiency of gas separation. These generators provide a high degree of control of nitrogen gas supply at minimal levels of maintenance. We have the capability to design and develop nitrogen generators as per the requirements of our customers.
How it works?
The nitrogen generator produces nitrogen gas from atmospheric air using molecular sieves separation technique. It uses a carbon molecular sieve which has ability to preferentially remove oxygen from air. Our proprietary technique gets higher efficiency of gas separation.

Nitrogen generator consists of two beds filled with carbon molecular sieves. When compressed air is passed, Nitrogen comes out as product gas from one bed while other bed is simultaneously regenerated by depressurization to atmospheric pressure. This process of gas separation is called "Pressure Swing Adsorption" (PSA).
Nitrogen Purity
From nitrogen generator gas of purities from 99% to 99.9999% can be produced. simple psa unit produces raw nitrogen of 99% purity. By adding purification unit to PSA unit, high purity nitrogen can be produced.

Advantages
  • Automatic Start-up time is only 5-Minutes.
  • Nitrogen gas supply always under your control.
  • Self-contained skid mounted units for easy site installation.
  • Very low maintenance costs.
  • Very high reliability to run un-attended plant.
  • Carbon Molecular Sieves life is minimum 15-years and in most cases it lasts the whole life time of Gas Generator.
Nitrogen Capacity
Nitrogen Generators are tailor-made equipment and are manufactured as per customer's requirements. However, standard units are available in the capacity of 1, 2, 5, 10, 25, 50, 75, 100, 150, 200, 300 NM3/hr. The Gas Generators can be manufactured in any desired capacity.
Nitrogen Pressure
Standard Nitrogen Generator produces nitrogen at 5.5 kg/cm2g pressure. This pressure comes automatically as feed air pressure to the PSA unit is around 7 kg/cm2g. However, by increasing feed air pressure to 10kg/cm2g, Nitrogen can be produced even at 8.5 kg/cm2g. But, at high pressure operation, depressurisation losses during regeneration are high, which results in high operation cost.

It is most economical to run nitrogen generators at 7 kg/cm2g pressure and produce nitrogen at 5.5 kg/cm2g pressure. If nitrogen is needed at higher pressure, we can provide a nitrogen booster compressor after the gas generator. By this addition, it is possible to compress nitrogen gas to any high pressure.

Nitrogen Membrane System
How it Works?
Creative OZ-Air (I) Pvt Ltd
Membrane nitrogen generators are built and supplied supplied by creative as skid, shop assembled units and include all equipment and instrument for generation of nitrogen gas of specified flow and purity. Higher the nitrogen purity level, lower is the nitrogen gas quantity and so operating cost increase membrane separator modules are imported from world leading manufacturer.

Nitrogen generator consists of two beds filled with carbon molecular sieves. When compressed air is passed, Nitrogen comes out as product gas from one bed while other bed is simultaneously regenerated by depressurization to atmospheric pressure. This process of gas separation is called "pressure swing adsorption" (PSA).

Nitrogen Gas System Consist of :
  • Air compressor system with cooler
  • Moisture separator with automatic drain and high level alarm
  • Air dryer to make air sub- saturated
  • Coarse and one fine coalescing filter for oil and solid particles removal
  • Fine Micron Filter
  • N2 Separation Membrane Modules
  • N2 Gas Tanks

Membrane Nitrogen System
Compressed air is provided from dedicated air compressor to separate nitrogen from air by using membrane technology. A feed air cleaning system is provided ahead of the membrane separator to provide clean air, free from oil, water droplets and solid particles. The clean air will allow for high efficiency nitrogen production and ensure long life of the membranes.
