The problem of environmentally friendly technology for the recycling of off-grade propellant oxidizers (melange) is considered. The process scheme for production of nitric acid in a packed absorber as consequence of blowing off nitrogen oxides from melange with oxygen. Commercial nitric acid (60-65% wt.) is formed as a result of mixture with stillage residue. The basic parameters of the process are presented.
