摘要： Apparatus for treating acid gas-containing flue gases to remove acid gases therefrom. Apparatus in accordance with the present invention include a device for heating an admixture of calcium alkali and calcium-reactive silica and/or alumina to above ambient temperatures for a period of time so as to facilitate the formation of acid gas-absorbing calcium silicates or aluminates. These apparatus further include a chamber for receiving activated absorbing components from the heater chamber wherein the activated absorbing component is admixed with gas to allow absorption of acid components therefrom. After absorption of acid components from the gas, the apparatus separates the treated gas from the spent absorbing component. Examples disclosed herein demonstrate the utility of these apparatus in achieving improved sulphur-absorbing capabilities. Additionally, disclosure is provided which illustrates preferred configurations for use in connection with coal-fired generating plants.

摘要： A novel electrostatic precipitator includes an electrostatic collector section with discharge electrodes positioned between pairs of grounded collector electrodes, a gas entry port located upstream of said electrostatic collector section, and a transition section between the gas entry port and said electrostatic collector section into which an aqueous acid gas neutralizing agent is sprayed into a gas stream. An additional collector section may be interposed between the gas entry port and the point where the acid gas neutralizing agent is injected into the gas stream. The collector section may comprise alternating charging and short collection sections in which the grounded electrodes of adjoining charger and collector sections are connected. A liquid spray removes particulates collected on the grounded electrodes of the collector sections.

摘要： An electrostatic precipitator includes a plurality of collector sections having parallel collection plates, defining gas flow lanes therebetween, and a bag filter section containing a plurality of parallel, elongated filter fabric bag elements. A plurality of corona discharge wires for charging solid particulates entrained in the gas flow entering the bag filter section are disposed parallel to and interspersed among the bag elements. Both the bag elements and the corona discharge wires within the bag filter section depend from a common plate member. Gas flow is from the outside of the bag elements to the inside and out through apertures in the supporting plate.

摘要： The present disclosure relates to improved processes for treating acid gases to remove acid gas components therefrom. Processes in accordance with the present invention include preparing a calcium silicate hydrate sorbent in the form of a semi-dry, free-flowing powder, and treating the gas with the powdery sorbent, such as by injecting the sorbent into a stream of the gas. The powdery sorbents may be prepared by slurrying/drying or pressure hydration techniques. Examples disclosed herein demonstrate the utility of these processes in achieving improved acid gas-absorbing capabilities in both lab-scale and pilot plant studies. Additionally, disclosure is provided which illustrates preferred plant design configurations for employing the present processes using conventional dry sorbent injection equipment. Retrofit application to existing plants is also addressed.
