(1) High mass transfer efficiency is the selection principle. The filler is required to provide a large gas-liquid contact area; in other words, it needs to have a high specific surface area. Moreover, the surface of the filler must be easily wetted by the liquid, as only a wetted surface can serve as a gas-liquid contact surface. (2) Selection is made based on the principles of high production capacity and low gas pressure drop. The packing layer is required to have large voids. (3) Selection is made on the principle of avoiding deflection and gullies. (4) Durability is the selection principle. The selected filler is required to have good corrosion resistance, high mechanical strength, and the necessary heat resistance. (5) The selection principle is easy availability and low cost.
