Impurity's n2
WitrynaPure gases are classified by grade. The first digit of the grade classification indicates the 'number of nines' purity, e.g. N3.0 = 99.9% purity. The second digit is the number following the last nine, e.g. N4.6 helium has a guaranteed minimum purity level of … WitrynaThe liquid nitrogen wash has the function to remove residual impurities like CO, Ar and CH4 from a crude hydrogen stream and to establish a stoichiometric ratio H2 / N2 = 3:1. Carbon monoxide must be completely removed, since it is poisonous for the ammonia synthesis catalyst. Ar and CH4 are inert components enriching in the …
