Gas holdup in tapered bubble column using pseudoplastic non-Newtonian liquids

摘要

Experimental studies on the gas holdup in two tapered bubble columns using non-Newtonian pseudo-plastic liquid have been reported. The effects of different variables such as gas flow rate, liquid viscosity, bed height, and orifice diameter of sieve plate on gas holdup have been investigated. An empirical correlation has been developed for the prediction of the gas holdup as a function of various measurable parameters of the system. The correlation is statistically acceptable.
