ABSTRACT:
This invention is based on the factors that both oxygen gas and nitrous oxides as gas are paramagnetic; as well as are quite soluble in saturated halogenated hydrocarbon liquids; whereas nitrogen is not paramagnetic; thus providing a means of separation of the oxygen and nitrous oxide from the nitrogen by high intensity magnetic forces created by an electromagnet.
The absorber liquid, saturated with dissolved oxygen and nitrous oxides, or ammonia is then ozonated using the solvent or absorber liquid dielectric as the dielectric in an ozone generator.
The effluent is stripped of nitric oxide with water to form nitric acid or by reduced pressure to recover nitric oxide.
