Abstract

The prediction of removal efficiency of gas in liquid jet ejector is an important factor as it influences the design of the mass transfer equipment. The major factors which affect the efficiency of jet ejector are flow rates like gas and liquid and the concentration of absorbing liquid and solute in the gas. This paper deals with statistical modeling for removal efficiency of gas in multi nozzle jet ejector for industry scale jet ejector. The developed model is based on statistical techniques to predict removal efficiency for variation in gas and liquid Concentration. The model is simulated using STATGRAPHICS PLUS 4.0 software for plotting the response surface. The same model is validated by experimental data of industry scale jet ejector .
