Characteristics of Gas-liquid Mass Transfer and Interfacial Area in a Bubble Column

Gas-Liquid Interfacial Area, Bubble Size and Liquid-Phase Mass Transfer Coefficient in a Three-Phase External Loop Airlift Bubble Column

The interfacial area a was measured by the sulfite oxidation method in a three-phase external loop airlift bubble column suspending completely the different concentrations of ion exchange resin particles in aqueous carboxymethyl cellulose (CMC) solutions with a wide range of viscosity. The column had been previously studied for the circulating liquid velocity UL, gas holdup G and volumetric gas...

Investigation of Packing Effect on Mass Transfer Coefficient in a Single Drop Liquid Extraction Column

Experimental Study and CFD Simulation of Mass Transfer Characteristics of a Gas-Induced Pulsating Flow Bubble Column

Oxygen gas-liquid mass transfer coefficient was measured in a gas-induced pulsating flow bubble column. Pulsating amplitude had a great influence on kla under pulsating state of equal base flow and pulsating flow, which was enhanced up to 30 % compared with that under steady state; however, it had a negative effect on mass transfer under a fixed low base flow. It was also found that kla had a n...

A Comparative Study of Interfacial Area Obtained by Physical and Chemical Methods in a Bubble Column

Determination of interfacial areas in absorption processes have been experimentally investigated in a bubble column using a physical method (photographic method) and a chemical method (Danckwerts ́ method). Experiments were conducted in a vertical column 11.3 cm in diameter and 108.6 cm in height. The range of variables used is common for both methods. All experiments were carried out in batch r...

Determination of Interfacial Area in Gas-Liquid Two Phase by Light Transmission

The purpose of the present paper is to develop light beam method to measurement of interfacial area in a rectangular gas-liquid bubble column. Total interfacial area can be determined in bubble column filled by transparent liquid by light transmission method. According to pervious researches, the fraction of parallel light is function of interfacial area and optical path l...
