ABSTRACT:
Waste gases streams, particularly products of combustion contain quantities of nitrogen oxides which are damaging to the environment. Dissolving or absorbing these gases in an inert, nonmagnetic, absorber liquid provides a media which can then be passed through a high intensity magnetic field. The nitrogen oxides are subject to paramagnetic forces and thus migrate in the liquid to the poles of the magnet. Supersaturation of the nitrogen oxides near the vicinity of the poles causes the absorptive capacity of the liquid to be exceeded and the nitrogen oxides are thus stripped from the liquid. Gases such as carbon dioxide, carbon monoxide, sulphur oxides, hydrogen sulphide, hydrogen chlorine, among many, are not paramagnetic and thus remain in the liquid, to be stripped by other means and the liquid reused.
