Mass Transfer Operations Pdf. The transport occurs from a region of higher concentration to lower concentration. Total diffusion molecular diffusion convection term convection term eddy diffusion molar flux due to convection convection term concentration mass transfer velocity c a.
The component moves to the direction of reducing concentration gradient. Thus the absorption by a solvent liquid of a solute from a carrier gas involves mass transfer of the solute through the gas to the gasliquid interface across the interface and into the liquid. Separations based on molecular movement toward a favourable phase for separation of dissolved components eg.
Download principles and modern applications of mass transfer operations pdf books.
Mass transfer operations author. The common denominator in mass transfer processes is that species fluxes occur within a phase when there are compositionvariations within that phase. It serves equally as a textbook for undergraduate senior and graduate students in a wide variety. Single and multi component absorption treybal mass transfer operations 277 295 3.
