Method for removing particulate matter from a gas stream and a method for producing a product using the removed particulate matter
A method is described for removing particulate matter from a gas stream by injecting charged particles into the gas stream to form a large charged surface area to induce charges on the entrained particulate matter. The injected material may be an adsorbent or an absorbent and may be reactive with the gases in the gas stream. The charged particles contained in the gas stream together with the injected particles are passed through a porous moving bed of media such as silica rock; as a result of the electrical charge as well as inertial impact forces on the respective particles, the particles become attached to the media which is continuously changed after it has captured the fine particulate matter. The media, together with attached sorbent additive and particulate matter, may then be incorporated into a product the manufacture of which generated the particulate matter.
