| Abstract |
The report gives results of an evaluation of the Shell Flue Gas Treatment process in a pilot-scale test for simultaneously reducing the emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) from flue gas produced in a coal-fired utility boiler. Flue gas leaving the economizer at about 400 C with a full load of fly ash was contacted with a copper-on-alumina acceptor/catalyst in a parallel-passage reactor. SO2 was removed by reaction with the acceptor, and the selective reduction of NOx with ammonia (NH3) was catalyzed. Regeneration of the acceptor at 400 C with hydrogen released the sulfur as concentrated SO2 which can be processed into a marketable byproduct. Estimates of capital and operating costs increased by 12 and 21%, respectively, due to the effect of fly ash with further increases of 7 and 5% to compensate for the combustion of NH3 at initiation of acceptance. |
