Modeling of the Process in a Packed Fractionating Column with Diffusive Liquid Phase Flow Pattern

Working line and mass transfer equations are derived analytically for rectifying and stripping sections of a packed fractionating column with a diffusive continuous liquid phase flow pattern. A calculation algorithm is proposed and the obtained process and geometric parameters are compared with the same parameters of the same column calculated by the standard algorithm, taking account of the fact that the disperse gas phase has an ideal-displacement flow pattern and the continuous liquid phase has an ideal-mixing flow pattern.
