MASS TRANSFER AND SEPARATION syllabus, JNTU (2007-2008)

UNIT I: INTRODUCTION TO MASS TRANSFER AND DIFFUSION

Introduction to Mass Transfer Operations; Fick’s Law of Diffusion, Gas diffusion and Liquid diffusion (one component transferring to non-transferring component and equimolar counter diffusion.) Diffusivity estimation (Stefan’s experiment); permeability, distribution of gas and liquid components through solid, diffusion of biological solutes in liquids, diffusion in biological gels.

UNIT II: MASS TRANSFER CO-EFFICIENT

Definition of k_L, F-type, K-type coefficients, Dimensionless numbers, Sherwood number, Stanton number, Schmidt number; estimation of MTC for the case where mass is diffusing from solid wall to bulk liquid.
