Thermal diffusion in a packed column

A performance analysis is presented for packed thermal-diffusion columns; a method is given for determining the Soret coefficient for a packed column, and test results are presented.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 30, No. 5, pp. 906–913, May, 1976.     

Mechanism of internal mass transfer in deep drying of polymer materials

A mass-spectrometric method is used to study the drying kinetics of polyolefine. It is shown that the low rate of deep drying is associated with the removal of the solvent by diffusion through the solid phase of the polymer.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 33, No. 4, pp. 627–634, October, 1977.     

Theory of deep drying of finely porous bodies and experimental verification of theory

Approximate formulas for calculating the initial phase of the deep drying of finely porous bodies are obtained for the case of random adsorption isotherms. Examples of calculations using these formulas showing a satisfactory agreement with experimental data are given.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 32, No. 5, pp. 800–805, May, 1977.     

Calculation of internal-mass-transfer coefficients in porous bodies on the basis of adsorption isotherms

Formulas relating the mass-transfer coefficients in porous bodies to the adsorption isotherms and coefficients of internal diffusion of vapor and adsorbed material are derived.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 32, No. 4, pp. 649–653, April, 1977.
