Gerador de nitrogênio PSA alta pureza

PSA Nitrogen Generator High Purity

Carbon molecular sieve can simultaneously adsorb oxygen gas and nitrogen gas in the air, and its adsorption capacity also increases with the increase of pressure, and there is no significant difference in the equilibrium adsorption capacity of oxygen and nitrogen at the same pressure. Therefore, it is difficult to complete the effective separation of oxygen and nitrogen only by the change of pressure. If the adsorption rate is further considered, the adsorption characteristics of oxygen and nitrogen can be effectively distinguished. The diameter of oxygen molecules is smaller than that of nitrogen molecules, so the diffusion rate is hundreds of times faster than that of nitrogen, so carbon molecular sieves absorb oxygen very quickly, and the adsorption reaches more than 90% in about 1 minute; at this time, the adsorption capacity of nitrogen is only 5%. So the adsorption is mostly oxygen at this time, and the rest is mostly nitrogen. In this way, if the adsorption time is controlled within 1 minute, oxygen and nitrogen can be initially separated, that is to say, adsorption and desorption are realized by pressure difference, adsorption when the pressure increases, and desorption when the pressure decreases. The difference between oxygen and nitrogen depends on the speed difference between the two being adsorbed, which is achieved by controlling the adsorption time. The time is controlled very short, oxygen has been fully adsorbed, and nitrogen has not yet been adsorbed, and the adsorption process is stopped. Therefore, the pressure swing adsorption nitrogen production must have a pressure change, and the time should be controlled within 1 minute.

Products Features of Nitrogen Making Machine

1. Small size, easy to move, small space, easy operation, easy maintenance.
2. The demand for compressed air is only 50% of the normal type of nitrogen generator,greatly reducing the energy consumption and conpressor cost.
3. The air compressor configuration of electricity demand is leass and normal, 220V electric power id suitable, it solves the user doesn;t have 380V supply concern.
4. Compared to the normal type of nitrogen generator,this new system nitrogen gas purity and flowrate are both stable, this design makes the system achieve more stable with low comsumption, all the technical indicators are qualifiled.

The nitrogen generator is mainly composed of compressed air purification unit, compressed air buffer unit, oxygen and nitrogen gas separation unit, nitrogen buffer unit and control unit. Followed by filter, refrigerated dryer, degreaser, air storage tank, adsorption tower, buffer tank, (purity, flow, pressure) measurement, qualified nitrogen discharge.

Our equipments are customised according to the clients' requirement. So do you confirm the technical demands of N2? (such as N2 purity, flow and pressure and ect.) Please feel free to send your request or question to us.
