To acquaint students with different mass transfer contacting systems, viz., liquid-liquid, solid-liquid, gas-solid, and their technical insights.

To develop a detailed know-how on designing process equipment involving simultaneous heat and mass transfer from an industrial perspective.

To emphasize gaining knowledge on more recently developed unit operations like supercritical fluid extraction, adsorption, and membrane separation.

The students will develop a fundamental know-how on the concepts of humidity and read a psychrometric chart for design calculations.

The students will be acquainted with processes involving simultaneous heat and mass transfers.

The students should be able to design process equipment like cooling towers and adsorbers using standard graphical and analytical techniques.

The students would learn methods of equilibrium stage calculations for liquid-liquid and solid-liquid extraction systems via graphical and analytical techniques.

The students should be able to justify a process selection, find optimum operating conditions, and theoretically troubleshoot process anomalies.
