Title:
亜酸化窒素の除去方法
Document Type and Number:
Japanese Patent JP5158717
Kind Code:
B2
Abstract:
Hydroxylamine is formed in a reactor through a partial hydrogenation of nitric oxide gas (NO) with hydrogen gas (H2) in an aqueous medium with nitrogen gas (N2) as an inert gas. The formation of the hydroxylamine forms nitrous oxide gas (N2O). The gases and the water vapor are flowed away from the reactor in a vent gas stream enabling recycling of the gases. The N2O is removed from the vent gas stream to reduce flammability. Once the N2O is removed, the NO, H2, and N2 are recycled and re-used in the reactor to form additional hydroxylamine. The N2O removed from the vent gas stream is of high purity and can be commercially sold or economically discarded.
