Approximate Methods of Estimation of Mass Transfer Rates in Ternary Gas Systems

Abstract

Experiments on vaporization of binary solutions into a turbulent air stream at atmospheric pressure and room temperature were carried out in a wetted-wall column. When the concentration of diffusive components is dilute, the diagonalization procedure proposed earlier was found not always to be usable under some conditions. The applicable conditions of the above procedure were confirmed experimentally. Approximate equations of mass transfer rates were proposed, utilizing a linearized method. The validity of the equation and the conditions under which it can be applied were then ascertained experimentally. The conditions under which the mass transfer rates of two diffusive components in ternary gas systems can be dealt with as the diffusion of one gas in binary systems were ascertained, using experimental data. © 1980, The Society of Chemical Engineers, Japan.
