Sparingly Soluble Gases Physical Absorption Enhanced by Presence of Dispersed Toluene Droplets in Water

Abstract In this work,the enhancement of gas-liquid mass transfer was studied under the normal pressure and at normal temperature with the presence of the dispersed liquid phase(toluene) by using the sparingly soluble gases(propane and hydrogen) physical absorption process.The mass transfer coefficient and mass transfer enhancement factor can be calculated by measuring the variation of gas(propane and hydrogen) pressure versus time.The result shows that the enhancement factor increases significantly with the presence of the dispersed phase in the condition of the mass transfer component possessing larger partition coefficient in continuous phase and dispersed phase or possessing larger relative diffusion coefficient with the dispersed phase dispersed with finely droplets.Enhancement factor increases with volumetric fraction of dispersed phase increasing,but the gradient becomes smaller;and the effects of enhancement decreases with a relative high mass transfer coefficient in pure water.
