The importance of Mass Transfer operations in chemical processes is insightful. There is scarcely any industrial process that does not require a preliminary purification of raw materials or final separation of products. This is the realm of mass transfer operations. 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 course 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.
