Abstract
A process for flue gas desulfurization or nitrogen oxide removal in a fluid using a magnetically stabilized fluid cross-flow contactor of the panel or radial reactor type wherein ferromagnetic bed solids are structured or stabilized by the action of a magnetic field.
Claims11
A process for flue gas desulfurization or nitrogen oxide removal, said process comprising the steps:
- (a) continuously introducing and removing a bed of solids through at least one porous chamber in a descending manner or direction, said bed of solids comprising a plurality composition capable of accepting sulfur oxide and/or nitrogen oxide;
- (b) structuring and controlling the porosity in said bed by applying a magnetic field to said bed in a manner such that the magnetic field is substantially colinear with the external force field within said chamber;
- (c) passing a gas containing sulfur oxides and/or nitrogen oxides through said descending bed of solids in a manner such that it has a velocity component substantially perpendicular to the external force field and the applied magnetic field within said chamber and withdrawing a gaseous stream substantially free of sulfur oxides and/or nitrogen oxides.
