Abstract
To remove nitrous gases from gas mixtures there is needed a process and apparatus by which they can be eliminated quickly, without formation of secondary waste and as cheaply as possible. This is done by scrubbing the nitrous gases out of the gaseous mixture with 15-50% nitric acid solution and treating this solution additionally with gaseous oxygen, especially atmospheric oxygen.
