Chugoku Electric Power Co., Inc. and Heavy Mitsubishi Heavy Industries, Ltd. developed a new type of absorber, the Double-Contact-Flow Scrubber (DCFS). DCFS is an easily maintainable absorber of simple construction with low initial cost and low power consumption for the wet limestone-gypsum flue gas desulfurization process. Absorbent slurry is spouted up from special type of nozzles located at the bottom of the absorber, creating a pillar of absorbent slurry to achieve a good gas-liquid contact. The only internal components of the absorber are the header pipes and nozzles, resulting in the simplicity of construction with lower cost, as well as easy maintenance due to the lack of scale deposits. This paper shows the performance results of DCFS operation.
