| Abstract |
The double alkali system is a relatively new flue gas desulfurization (FGD) process that was developed to overcome some of the problems associated with lime/limestone systems without losing any of their advantages. The problems generally associated with lime/limestone systems are scaling, plugging, and erosion, all of which result from the absorbant's being in slurry form. The double alkali system overcomes these problems by using a soluble absorbant. The inexpensive raw materials and the relatively simple processing steps that are the major advantages of the lime/limestone systems are also advantages of the double alkali system. Pilot plant investigations on the application of double alkali to combustion sources began in 1973. Now three utilities, with a total capacity of 1102 MW, and three industrial-sized boilers in the United States are installing this system. |
