The
mass transfer operations are largely the responsibility of chemical engineers,
but increasingly practitioners of other engineering disciplines are finding them
necessary for their work. The objective of this note is to provide a means to
teach undergraduate chemical engineering students the basic principles of mass
transfer and to apply these principles, aided by computational tools, to the
design of equipment used in separation processes.
