Abstract
Experimental data on liquid holdup are collected over a wide range of variables in a turbulent bed contactor (TBC) with a 3 mm projection of the gasket to block the free area of the distributor plate near the wall so that the channeling of liquid along the wall is avoided. The variation in dynamic liquid holdup based on static bed height ε ld,st with gas velocity, liquid velocity, particle diameter and density, static bed height, free-open area of the distributor plate and dimensions of downcomer are discussed for Type I and Type II turbulent bed contactor. Correlations are developed to predict the dynamic liquid holdup. The liquid holdup obtained through quick closing valve technique is compared with the liquid holdup obtained through residence time distribution (RTD) method.
