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： 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.

摘要： The present disclosure relates to improved processes for treating hot sulfur-containing flue gas to remove sulfur therefrom. Processes in accordance with the present invention include preparing an aqueous slurry composed of a calcium alkali source and a source of reactive silica and/or alumina, heating the slurry to above-ambient temperature for a period of time in order to facilitate the formation of sulfur-absorbing calcium silicates or aluminates, and treating the gas with the heat-treated slurry compounds. Examples disclosed herein demonstrate the utility of these processes in achieving improved sulfur-absorbing capabilities. Additionally, disclosure is provided which illustrates preferred configurations for employing the present processes both as a dry sorbent injection and for use in conjunction with a spray dryer and/or bagfilter. Retrofit application to existing systems is also addressed.
