Abstract The paper gives results of applying the dual alkali (D/A) flue gas resulfurization (FGD) process to a 280-MW coal-fired power plant. (NOTE: D/A is a generic term applied to FGD systems that use soluble alkali to absorb SO2 and then react the spent scrubber solution with lime and/or limestone to regenerate the alkali and produce a waste calcium-sulfur salt for disposal. Features that distinguish D/A from conventional direct lime and limestone scrubbing include: (1) use of a clear solution, rather than a slurry, for contacting the flue gas in the absorber; and (2) reaction of the solution in a separate absorbent regeneration section to form the waste solids, rather than forming the waste solids as a part of the scrubbing operation.) The FGD system met all acceptance test process guarantees except filter cake properties (averaging 52.2 of a minimum required 55 wt% insoluble solids). The remaining guarantees were: SO2 emissions limit, particulate matter emissions, lime consumption, soda ash consumption, power consumption, and system availability. The demonstration started on May 1, 1980, and ended on May 31, 1981.
