| Abstract: | Gas Liquid interphase mass transfer is widely encountered in chemical process,because of the limitation of experimental techniques,the conventional theories of interphase mass transfer can not be confirmed experimentally.The micro mechanism of interphase mass transfer has not yet been known clearly.Interfacial properties have an important act on gas liquid mass transfer.Molecules are damped to pass interface by interfacial free energy,interfacial free energy is related to interfacial and molecular properties.Owing to the existing of interfacial free energy,the concentrations of interfacial sides have obvious difference.The relation between the concentrations of two sides were derived in this paper. |
