Now, nitrogen gas has been used widely in gas drilling of the oil-gas well, three times oil production operations, well completion, well repair, pressure upkeep and gas storage. And the inertia of nitrogen and the high pressured nitrogen can be in collecting gas and the sweep of piping system to prevent inflammable gas burning and the underground pipes of oil field being corroded.

When the pressure rises, the carbon molecular sieve adsorbs the oxygen and produces the nitrogen gas. When the pressure decreases, the carbon molecular sieve starts to desorb the oxygen until the pressure equals to the ordinary pressure. At that time, the carbon molecular sieve desorbs the oxygen completely. The PSA nitrogen generator is usually equipped with adsorption towers. It controls the pneumatic valve by PLC, thus the two adsorption towers can produce the nitrogen gas alternatively. One tower adsorbs the oxygen and produces nitrogen gas, the other desorbs to regeneration to produces the required nitrogen.

SMT nitrogen generator combines the features of lead-free soldering in SMT industry, nitrogen purity is generally between 99.9%～99.999%, the flow of nitrogen generator of each soldering furnace is generally between 10～30Nm3/hr (special specifications are calculated according to actual flow), the dew point is between -40℃～-60℃, and nitrogen pressure is between 0.5-0.6MPa. SMT dedicated nitrogen making solution can make the flux correct and active, reduce the residual amount of flux, enhance soldering quality and make the soldered surface more attractive.
