Abstract: Rectification is a basic industrial method for separation of liquid homogeneous multicomponent mixtures to obtain individual components of high purity. Surface tension is hydrodynamic phenomen with complex effect on the kinetics of mass transfer process. Studying the phenomenon by rectification, it has been established that positive mixtures form stable interphase boundary and show higher efficiencies. To describe the disturbances at the interphase boundary induced by the gradient of the surface tension, a number of experiments were carried out aiming to find explanation of the mass transfer processes taking place under the effect of Marangoni. The aim of the present work is to obtain experimental data on the influence of Marangoni effect on the efficiency of separation of two model mixtures (chloroform-benzene and methanol - water) in a glass rectification column with one sieve tray.
Keywords: rectification, surface tension, effect of marangoni
