ABSTRACT OF THE DISCLOSURE The improved flue gas desulfurization process is effective for removing sulfur dioxide in the flue gas with a lime-bearing material in a fluidized lime reactor (50, 110, 164, 426). The effectiveness of the process is due primarily to the presence of sulfur trioxide in the gas, the sulfur trioxide being generated in a catalytic convertor (40, 156, 41a) and a bypass circuit (20, 408) transmitting a portion of the flue gas past the catalytic convertor (40, 418). Sulfur trioxide may also be directly injected by duct injection in order to enhance the removal of sulfur dioxide from flue gas in the fluidized lime reactor (110, 164). In the initial phase, the duct injected sulfur trioxide efficiently raises the temperature of the lime-bearing particles (7) from the exothermic reaction with lime, resulting in the establishment of the steep temperature and sulfur oxides gradients which induce an autogeneous conversion of sulfur dioxide to sulfur trioxide. The converted sulfur trioxide is rapidly removed by the lime-bearing particles (7). Sulfur oxides can also be removed by injecting lime-bearing particles that are consider- ably hotter than the surrounding gas in the reactor. The improved desulfurization process greatly reduces the capital investment and operating costs of the process, and maintains a high sulfur dioxide removal efficiency while producing a useful by-product.
