The sulfur removal performance of pressurized, fluidized-bed combustion power plants operated in the range of 16 to 20 atmospheres pressure is evaluated. This pressure range has previously received little attention and is of potential commercial interest. Eleven limestones and dolomites were characterized and tested for sulfation activity under a variety of conditions of temperature, pressure, excess air, and particle size to provide the basis for commercial sulfur removal projections. A pressurized thermogravimetric balance was used to obtain kinetic data. Sorbent particle diameter was found to have a significant effect on the sulfation rate, temperature and excess air less so. Great variation between the behavior of the eleven sorbents was apparent. Increased pressure results in a need for increased gas residence time or reduced sorbent particle size in the bed in order to achieve calcium-to-sulfur ratios compared with lower pressure operation.
