When a system contains two or more components whose concentrations vary from point to point, there is a natural tendency for mass to be transferred, minimizing the concentration differences within a system. The transport of one constituent from a region of higher concentration to that of a lower concentration is called mass transfer. The topic in these notes are as follows : Introduction to Mass Transfer, Humidification, Drying, Crystallization, Membrane Seperation.
