An experimental study on effect of random packing on performance of seawater FGD absorption system

Guan Yiming Wang Hongliang Liu Tao Wang Xiaoming Xue Jianming(Guodian Science and Technology Research Institute(State Power Environmental Protection Research Institute),Nanjing 210031,China)  
The effects of packing type and packing height on desulfurization efficiency and pressure drop were studied in a pilot plant of the seawater FGD absorption system.In the experiment,a comparison between spray tower and packed tower was carried out.The packed tower was respectively filled with type A,type B,type C random packing and packing height was varied from 0.6 m to 1.8 m.The results show that the desulfurization efficiency of packed tower is better than that of spraying tower.When superficial gas velocity is 3 m/s,the comprehensive performance of type C is optimum.When superficial gas velocity is less than 2.5 m/s,type A has the best comprehensive performance among the three types.Although higher packing height would decrease spraying volume and pressure drop under the same desulfurization efficiency,other factors should be taken into account in the project design,such as the height of absorption tower,the loading of packing support,etc.
