MASS TRANSFER OPERATIONS-I
By
Mr. M. Sreenivas
Assistant Professor
Department of PE&PCE
,Text books:
1. MASS-TRANSFER OPERATIONS By Robert E. Treybal (3rd Edition
2. Principles of Mass Transfer and Separation processes by Binay K
Dutta
, Unit-1
Introduction to Mass Transfer Operations &
Diffusion
Definition:
• Transfer of material from one homogeneous phase to another. With or withou
phase change.
• Examples:
• The phenomenon of transport of oxygen from air to water
• Recovery of penicillin from fermentation broth.
• Removal of CO2 & H2S from natural gas.
• Aeration of the pool of water in an aquarium.
• Distillation, Drying, Absorption, Adsorption, Leaching, Liquid extraction.
• Driving force - Concentration difference
• Solution, solute, solvent and carrier gas/liquid.
, Direct contact of Two Immiscible Phases:
Phase contacts:
• 3-states of aggregation
• Gas-Liquid Phase contact
• Gas-Gas
• Gas-Solid
• Liquid-Liquid
• Liquid-Solid
• Solid-Solid
