The article gives results of testing (between February 1982 and March 1983) on a pilot-scale, limestone, dual-alkali, flue gas desulfurization (FGD) system at IERL-RTP, where testing started in 1979. These results that significant improvement in soda ash consumption and filter cake quality could be achieved with proper system control. Causes of system upset by non-settleable solids were also identified and demonstrated in tests. The article not only gives highlights of recent pilot plant testing, but also generally discusses limestone dual-alkali processes.
