Membrane generators operating principle is based on gas mixture separation due to its components selective penetration through a polymer membrane. Membrane modules consisting of thousands of hollow polymer fibers are a main part of the generator.
Compressed air membrane separation technology is carried out according to the following scheme. Compressed air from the compressor is supplied to the air treatment system, where it is cleaned from moisture, oil and mechanical impurities. The pre-cleaned and dried air stream is then fed to an electric heater to provide the optimum separation temperature. In the separation unit, due to the structure of the fibers, a part of oxygen and a certain amount of argon passes into the intertube space of the membrane, while the product nitrogen is discharged from the opposite side of the membrane. After analyzing for the required oxygen content, the product nitrogen is sent to the receivers and then directly to the consumers.
Technical specifications:
- Nitrogen purity: up to 99.6 % vol.;
- Performance: up to 5000 m3/hour;
- Pressure: up to 12 bar (exc.);
- Product gas dew point: < -60 °C.
Nitrogen membrane generator advantages:
- Membrane modules durability – service life up to 15 years;
- Low maintenance costs – unlike the SCA generator, membrane generators require overhaul twice less often;
- Main unit parameters are monitored in automatic mode. The generator can also be equipped with a remote control system;
- Compact dimensions;
- Short system start and stop phases;
- High performance allows nitrogen production up to 5,000 m³/hour;
- Pressure up to 12 bar without booster compressor.
Application:
- Food industry – for packaging and product storage in a nitrogen environment;
- Petrochemical industry – for enhanced oil recovery during well development, for pipelines and equipment testing and purging;
- Metallurgy and coke-chemical production – to create inert environment for hardening, annealing, etc.;
- Mining industry – to create an explosion-proof environment in mines, to expand rock layers;
- Aviation – nitrogen gas is used to fill aircraft tires;
- To ensure explosion and fire safety in various technological processes, for nitrogen fire extinguishment;
- For underbalanced drilling using nitrogen as a formation fluid – during well development and workover, to clean bottomhole formation zone from mechanical impurities;
- For laser cutting – for metal oxidation protection, cooling and combustion products removal from the cutting zone.
Warranty on equipment supplied up to 24 months.
