Nitrogen was purified by adding carbon type nitrogen purification device. The principle of palladium carbon fiber deoxidation process is that nitrogen with purity of 99.9% is heated into the deoxidizer containing palladium carbon fiber, the oxygen in nitrogen and the carbon containing the catalyst react with the catalyst palladium as follows:
C + O2 = CO2
Under the action of Catalyst, the chemical reaction is complete and the content of residual oxygen in nitrogen after deoxidation is less than 3 ppm. The deoxidized nitrogen is cooled and enters the adsorber with molecular sieve. The moisture and CO2 in nitrogen are deeply adsorbed by molecular sieve. After filtration, high purity nitrogen can be obtained. The advantages of the process are that there is no hydrogen content in the product nitrogen, and it is especially suitable for the occasions where the hydrogen content is strictly required.
However, the deoxidizer (palladium carbon fiber) in the deoxidizer is of a consumption type. The deoxidizer replacement period of the unit we designed for your company is three months. After three months of use, continuous production can be ensured by switching the deoxidizer, another complete reaction of the deaerator is to replace the deaerator, “Divboair” to take into account the convenience of reloading, the design of feed and discharge mouth, then reload process simplified (each reload only 5 minutes) .
