摘要
It has been discussed in previous papers [1-7] that the design of packings capable of operating at extremely low liquid superficial velocity allows the development of effective countercurrent flow packed bed columns even if the concentration of the absorbed component is very low, the absorption is an equilibrium process, and the gas is well soluble in the liquid phase. The construction of the new packing is described in [7]. The present paper reports the results of an investigation of the pressure drop for dry and irrigated packings up to a gas velocity equal to 3 m/s (F-G factor equal to 3.3 kg(1/2) m(-1/2) s(-1)) as well as the equations for its calculation.
