Abstract: Hydroxylamine is formed in a reactor through a partial hydrogenation of nitric oxide gas (NO) with hydrogen gas (H 2 ) in an aqueous medium with nitrogen gas (N 2 ) as an inert gas. The formation of the hydroxylamine forms nitrous oxide gas (N 2 O). The gases and the water vapor are flowed away from the reactor in a vent gas stream enabling recycling of the gases. The N 2 O is removed from the vent gas stream to reduce flammability. Once the N 2 O is removed, the NO, H 2 , and N 2 are recycled and re-used in the reactor to form additional hydroxylamine. The N 2 O removed from the vent gas stream can be commercially sold or economically discarded.

The N 2 O is removed from the vent gas stream to reduce flammability. The method of removing N 2 O comprises the steps of (a) flowing the vent gas through a nitrous oxide adsorbent material comprising particles such that the N 2 O is adsorbed onto the particles; (b) forming a buffer zone comprising N 2 adjacent to the nitrous oxide adsorbent material; (c) flowing additional N2O through the nitrous oxide adsorbent material to displace the other gas; and (d) desorbing the N 2 O from the nitrous oxide adsorbent material. Once the N 2 O is removed, the NO, H 2 , and N 2 are recycled and re-used in the reactor to form additional hydroxylamine. The N 2 O removed from the vent gas stream is of high purity and can be commercially sold or economically discarded.
