Rationale:

In this subject the basic concepts of mass transfer are covered to enable the students to understand working of various mass transfer equipment’s like crystallizers and driers which are used in industries for purification of products. This course explains the fundamentals of mass transfer and techniques involved in mass transfer operations of humidification, drying and absorption. This subject intends to equip the students with the concept and principles of mass transfer operation, which are of prime importance in any chemical industry. Mass transfer equipment’s are an integral part of any chemical plant. This subject will help the students to operate and design various mass transfer equipment’s.
