ABSTRACT:
High temperature gas emissions from industrial power plant or environmental clean-up processes are subjected to an acoustic waveform having second harmonic content and appropriate second harmonic phase shift to impart a net acoustic Oseen force on particulate matter contained in the gas for removal of said matter. Particulate matter of 1 micron radius is positively excluded, while smaller particles are agglomerated by the sound wave. The acoustic waveform further enhances both sorption of injected sorbent particles for removal of sulfur oxides, and the efficiency of an in-line catalytic converter for removal of nitrogen oxides. The invention improves overall removal efficiency, can operate at very high temperatures, and does not produce any secondary waste, such as filters.
