TOTAL VOLUMETRIC MASS TRANSFER COEFFICIENT AT CO2 GAS ABSORPTION USING K2CO3 BY MSG PROMOTER

Determination of Volumetric Mass Transfer Coefficient in Gas-Solid-Liquid Stirred Vessels Handling High Solids Concentrations: Experiment and Modeling

Rigorous analysis of the determinants of volumetric mass transfer coefficient (kLa) and its accurate forecasting are of vital importance for effectively designing and operating stirred reactors. Majority of the available literature is limited to systems with low solids concentration, while there has always been a need to investigate the gas-liquid hydrodynamics in tanks handling ...

Evaluation of Mass Transfer Coefficient of Gas Absorption into Falling Liquid Film

The analytic, open-form solution for the steady-state, 2-dimensinal partial differential equation describing the concentration profile for the gas solute in a falling liquid film flowing under a steady-state laminar condition was shown. The overall mass transfer coefficient, c k , for a binary diffusion system, was evaluated in light of the analytic solution and was tested for oxygen absorption...

Mass Transfer Modeling of CO2 Absorption into Blended MDEA-MEA Solution

In this research, the thermodynamics and mass transfer of CO2 absorption has been studied in a mixture of MDEA-MEA amines. A relation is presented for mass transfer flux in the reactive-absorption process. For this purpose, the effective parameters on the mass transfer flux were investigated in both liquid and gas phases. Then, using dimensional analysis with the Pi-Buckingham theorem, the effe...

experimental investigation of power consumption, mass transfer coefficient and flow regime in gas-liquid dispersion systems

Prediction of the gas /liquid volumetric mass transfer coefficients in surface-aeration and gas-inducing reactors using neural networks

Almost all available literature correlations to predict the volumetric gas /liquid mass transfer coefficient, kLa in agitated reactors are systemsor operating conditions-dependent. In this study, two back-propagation neural networks (BPNNs), one dimensional and one dimensionless were developed to correlate kLa for numerous gas /liquid systems in both surface-aeration reactors (SAR) and gas-indu...
