NONSTATIONARY MASS TRANSFER NEAR THE SURFACE OF A CYLINDRICAL BODY

The problem of nonstationary diffusion of the target component to a phase that is external relative to the surface of a cylindrical body has been formulated and solved analytically. From the found solution the dependences have been obtained for calculating the instantaneous mass transfer coeffi cient and the phase-contact-time mean mass transfer coeffi cient, on the basis of which the process of extraction of technological pollutants from fi brous materials has been analyzed.
