purification of nitrogen by hydrogenation
technical indicators
nitrogen production of finished product: 10nm3/h-5000m3/h
the raw material purity of nitrogen: 99% (adjusted 98%-99.5% in between)
the product purity is more than 99.9995%.
hydrogen content: 1-1000ppm
oxygen content: less than 5ppm
the dew point: c = -60
working principle
nitrogen machine under certain pressure after purification treatment dry compressed air, the pressure swing adsorption effect, the dynamic effect of oxygen and nitrogen in carbon molecular sieve on the surface of the diffusion rate of oxygen in carbon molecular sieve on the surface of the diffusion rate is much higher than that of nitrogen adsorption is not balance, oxygen is carbon molecular sieve adsorption, nitrogen in the gas phase are concentrated, so as to realize the separation of oxygen and nitrogen, the carbon molecular sieve oxygen adsorption capacity with different pressure and have obvious difference, reduce pressure, oxygen molecules can the desorption carbon molecular sieve adsorption, the carbon molecular sieve regeneration, can be used repeatedly. the system is provided with two adsorption towers, tower desorption regeneration, using imported plc control cycles of two towers, in order to achieve continuous production of high-quality nitrogen.
product features
reliable operation of the whole machine
the organic combination of carbon molecular advanced nitrogen preparation process design, scientific structure, the distribution of the gas adsorption tower for composite bed structure, unique carbon molecular sieve loading process, specific measures and screen cylinder automatic protection device for pressing compensation, so that the carbon molecular sieve of the normal service life of up to ten years.
continuous production stability
the imported plc control system and the imported moving valve with a switching life of 2 million 500 thousand times are used to ensure the continuous and reliable operation of the device.
advanced control system
can choose the touch control system, using the human interface design, including a multi screen display, online display parameters of the purity of nitrogen, flow, pressure, fault signal, and the operation parameters can be modified online, with remote monitoring, remote signal and remote shutdown function, in a high degree of automation, simple operation, can achieve full control automatic, and user control system dcs
the unique online analog control display screen can show the process flow and valve switch status online, which is intuitive and convenient, and has strong detectability.
nitrogen quality stability
the nitrogen purity and pressure can be adjusted by the adsorption process, and the automatic release device is used to ensure the nitrogen production and purity, and the pressure is stable for a long time.
low operating cost
compared with other (including cryogenic nitrogen, membrane nitrogen, liquid nitrogen, cylinder nitrogen) in small and medium scale devices, the operating cost of psa nitrogen making machine is low.
good after-sales service
the perfect after-sales service system and marketing service network distribution to ensure that each customer is safe to use for a long time.
