Title:
EMISSION GAS PROCESSING SYSTEM WITH CARBON DIOXIDE CHEMICAL ABSORPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/142376
Kind Code:
A1
Abstract:
Disclosed is an emission gas processing system provided with a wet flue gas desulfurization device and a CO2 chemical absorption device, wherein issues caused by mercury in emission gas are solved and release of metallic mercury to the outside is prevented. The gas emission processing system is provided with: an air preheater (3) which heats combustion air for a fossil fuel combustion furnace; a dust-collection device (5) positioned in the wake flow of the air preheater (3); a wet desulfurization device (7) that provides a wet treatment of sulfur oxides in the emission gas; a CO2 chemical absorption device (11) that absorbs and separates CO2 from the emission gas; a heat exchanger for emission gas heat recovery (4) disposed between the air preheater (3) and the dust-collection device (5); a heat exchanger for reheating emission gas (8), that increases the emission gas temperature by using the heat recovered by the heat exchanger for emission gas heat recovery (4), disposed between the wet desulfurization device (7) and the CO2 chemical absorption device (11); and a catalyst (10) for oxidizing mercury in emission gas, disposed between the heat exchanger for reheating emission gas (8) and the CO2 chemical absorption device (11).
