By the use of the experimental data of many previous studies, a new correlation for the pressure drop of a packed column was obtained in this work. The total pressure drop is expressed as the sum of the dry pressure drop and the wet pressure drop. The dry pressure drop originates mainly from the friction of gas rising through the void of the packed bed, and is expressed by the Fanning equation. The wet pressure drop originates from the increase in net gas velocity because of the smaller void of the packed bed owing to the liquid holdup, and therefore it is expressed as a function of liquid holdup, gas velocity, etc. The liquid holdup consists of static and dynamic holdups, and is correlated separately.
