N.GN ON-SIT NITROGN GNRATION SYSTM COST-FFCTIV NITROGN GNRATION NGINRING FOR SUSTAINABL GROWTH
NRGY FFICINT NITROGN GNRATION Nitrogen can be generated on-site with HyGear s N.GN. On-site nitrogen production by HyGear increases the reliability of supply and offers more flexibility to the customer. The N.GN gives a significant cost reduction in comparison to nitrogen supply by cylinders. The highly efficient on-site nitrogen generator is based on HyGear s extensive experience in PSA gas separation technology and gas processing systems. The N.GN product line has a range from 10 Nm 3 /h up to 1000 Nm 3 /h. Due to its high quality components, the N.GN requires minimum maintenance while having extended operation lifetime. The systems are flexible in capacity and can be combined with HyGear s on-site hydrogen and oxygen generation systems to offer total on-site gas supply.

TCHNOLOGY In the first section of the N.GN atmospheric air is compressed. The compressed air is subsequently fed in the air treatment module (ATM), to remove water, oil and impurities. The ATM consists of multiple filters, a dryer and an activated carbon oil remover. The clean, dry and oil-free compressed air is captured in the buffer tank. AIR AIR RCIVR TANK PSA H 2 O O 2 N 2 CO 2 NITROGN STORAG IMPURITIS The second stage of the N.GN is the adsorption process. HyGear uses highly efficient Pressure Swing Adsorption (PSA) technology. The PSA separates the nitrogen from other gaseous species by using the differences in adsorption properties. The two parallel active vessels enable a continuous cleaning process. AIR COMPRSSOR AIR TRATMNT MODUL The produced nitrogen is stored in a storage tank to balance the pressure fluctuation and ensure a stable nitrogen supply. Depending on the required pressure, a compressor can be added. Highly efficient PSA technology The N.GN is based on very efficient and reliable PSA technology to increase the nitrogen production yield and purity. The N.GN has one of the world s best air-to-nitrogen ratios, resulting in minimised energy consumption. Qualitative adsorption material HyGear has selected the best Carbon Molecular Sieve (CMS) as adsorption material for the N.GN. This CMS minimises the air and power consumption, while maintaining the required purity levels over time. A special CMS filling method is used to ensure higher density and better distribution of the adsorption material. This increases the production efficiency and ensures a longer lifetime of the material. Selective air treatment The selective filtration module ensures accurate pre-treatment of the compressed air and prevents impurities and water from entering the PSA. Advanced compressor HyGear uses high quality compressors to minimise maintenance and shutdowns and to lower the energy consumption. Secure and easy operation An advanced control system is integrated in the N.GN, to monitor and control the performance of the system from HyGear s head office. The control system enables autonomous and safe operation.
