METHOD OF REMOVING NITROGEN ACIDS FROM AIR Russian patent published in 2005 - IPC

Abstract RU 2259864 C1

FIELD: physical or chemical processes and apparatus.

SUBSTANCE: method comprises flowing air through the chemical absorber of nitrogen acids that is composed of chemically absorbing base that absorbs nitrogen dioxide and sorbent-oxidizer that oxidizes nitrogen mono-acid up to nitrogen dioxide. The chemical absorber is made of n pairs of layers of chemically absorbing base and sorbent-oxidizer. Upon flowing throughout n pairs of the layers, the initial concentration of the nitrogen dioxide drops by a factor of 3ⁿ, where n is the total number of pairs of the layers.

EFFECT: reduced cost and enhanced efficiency.
