Wet Flue Gas Desulfurization with Seawater Hamon

Wet Flue Gas Desulfurization with Seawater HamonAt the outlet of the absorber, the clean gas is saturated and can be directly removed via a cooling tower or wet stack. Optionally the clean gas can be heated and routed to a dry stack. The seawater from the absorption zone is mixed with fresh seawater from the power plant condenser to increase the pH value and is then conveyed to the further treatment system.

Flue gas desulfurization/The Colstrip flue gas cleaning ...The combination of coal cleaning and fluegas desulfurization can be a better choice than scrubbers alone. An analysis of sulfur and ash removal for three coal types, West Kentucky No. 9, 11, and 12, shows that precombustion cleaning reduces the capital investment and operating costs for the scrubber's absorbent handling and preparation system and for sludge disposal.
