Pall ring packing has the advantages of great flux, smaller resistance, high separating efficiency and higher operation flexibility. Under the same pressure, the treatment amount can be more 50% than raschig ring. In the same capacity, the depressurization can be reduced by half, and the mass transfer efficiency can be increased by about 20%. Compared with raschig ring, this packing has the characteristics of large production capacity, strong resistance and large operation elasticity. In general, the same pressure drop is 50% to 100% higher than the raschig ring, and 50% to 70% lower than raschig ring with same process. The tower also has depressurization, which can save 20%-40% packing volume by adopting pall ring packing compared with raschig ring.
