This paper presents development of a cleaning robot for the sludge in sulfuric acid tank. The sulfuric acid is made during SOx capturing process, well known as flue gas desulfurization, and it has very strong corrosion characteristics. The cloud of micro dust in the flue gas settles as sediment in the acid tank. Because the fume produced by the sulfuric acid is very toxic, the sulfate sludge must be removed not by a worker but by an underwater robot having anti-corrosion capability. For this purpose, an underwater robot is developed with anti corrosion materials for its elements such as robot body, drive shaft, wheel, waterproofing seal, power cable, slurry pumping tube, etc. A series of experiments of sludge cleaning shows that the developed robot works well in the real sulfuric acid tank.

This paper analyzes the active coke FGD fundamental principles, structures and current applying situations, and calculates the initial investment active coke FGD and limestone-gypsum FGD. Moreover, it calculates the operating cost by raw material price and products price in China, and compares the initial investment cost and operating cost of the two FGD technologies in different usage period. This paper concludes that the high investment cost limits the wide application of active coke FGD, it can only be applied in some projects need sulfuric acid.

Abstract AL 4565 alloy has a high level of austenitizers, which provides the microstructure with a high resistance to sigma formation during welding. The high nitrogen also gives the alloy superior strength among the austenitics. Applications include flue gas desulfurization and handling seawater. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-906. Producer or source: Allegheny Ludlum Corporation.
