# Mass Transfer Operations I

Indian Institute of Technology Guwahati

Course outline:

• The general objectives of Mass Transfer Operations-I are to discuss the fundamental concepts of mass transfer principles and to apply those concepts to real engineering problems.
• This course will provide an overview of mass transfer operations at basic to an intermediate level. Coverage will be relatively broad.
This course applies the concepts of diffusion mass transfer, mass transfer coefficients, convective mass transfer, interphase mass transfer, equipment for gas-liquid operations, absorption, and distillation.
• Each topic will be covered in logical sequence with relevant examples.
The goal is to provide students with the theoretical/analytical background to understand mass transfer operations and to tackle the sort of complex problems.

Course details:

1. Diffusion Mass Transfer:
Introduction to mass transfer and diffusion, molecular diffusion in gases, liquids, biological solutions and gels.

2. Mass Transfer Coefficients:
Concept of mass transfer coefficients, mass transfer under laminar and turbulent flow past solids.
Boundary layers, theories of mass transfer and their applications, interphase mass transfer.
Equilibrium and diffusion between phases.
Use of mass transfer coefficients, mass transfer coefficients for different geometries, material balances and stages.
3. Equipment for Gas-Liquid Operations:
