Flue-gas desulfurization - Wikipedia

Most FGD systems employ two stages: one for fly ashremoval and the other for SO 2 removal. Attempts have been made to remove both the fly ash and SO 2 in one scrubbing vessel. However, these systems experienced severe maintenance problems and low removal efficiency. In wet scrubbing systems, the flue gas normally passes first through a fly ash removal device, either an electrostatic precipitator or a baghouse, and then into the SO 2-absorber. However, in dry injection or spray drying operations, the S

If CO 2 is to be separated, as much as 100 megawatts of a typical 500-megawatt coal-fired power plant would be necessary for today’s CO 2 capture processes based on the alkanolamines [4–6]. Therefore, it would be highly desirable if the flue gas mixtures can be used for CO 2 conversion but without pre-separation of CO 2 .

Flue gas - Wikipedia

At power plants, flue gas is often treated with a series of chemical processes and scrubbers, which remove pollutants. Electrostatic precipitators or fabric filters remove particulate matter and flue-gas desulfurization captures the sulfur dioxide produced by burning fossil fuels, particularly coal. Nitrogen oxides are treated either by modifications to the combustion process to prevent their ...
