Mass Transfer in Stirred Gas Liquid Contactors

The knowledge of gas liquid mixing is a vital part of chemical engineering discipline. The application of gas liquid dispersion is widely practiced in the industries nowadays where the gas liquid mass transfer rate is the main interest in the process. In order to enhance the mass transfer the volumetric mass transfer, the stirred tank contactor vessel is used in the industries as well as in the lab. However a problem arise when the parameters that affect the rate of mass transfer is not well studied and understood which can lead to bad operation of the gas liquid mass transfer in stirred contactor. Prior to the problem, three main parameters affecting the volumetric mass transfer in the gas liquid stirred contactor will be studied which is the impeller speeds and the flow rate of the gas flowing into the vessel. The proposed experiment will be conducted by varying the operating parameters. In studying the effect of gas flow rate to the mass transfer rate, the impeller speed and the power of the impeller is treated as the fixed variables and vice versa.
