7. Binary separation of Methanol-Water system in a bubble cap distillation column.
8. Determination of mass transfer coefficient using the wetted wall column.
9. Determination of steady-state flux through a ceramic composite membrane and estimation of its porosity.
10. Determination of removal efficiency of an adsorbent in treating model contaminants using a continuous packed bed adsorption column.

The basic aim is to conduct practical studies on various mass transfer operations for a thorough understanding and detailed insight to support the theoretical knowledge.

(i) The course would assist students to understand the molecular diffusion phenomena, concepts of mass transfer coefficients and their practical significances in different unit operations, and comparison of results with predictive models.
(ii) To be able to practically demonstrate operations in batch distillation columns (trayed and packed), and continuous packed absorption column to separate ideal binary solutions, and CO2 absorption respectively with basic understanding of vapor-liquid/gas-liquid equilibria.
(iii) To be able to operate, analyze, and compare the drying performances of fluidized bed and rotary dryers with fundamental understanding of humidity.
(iv) To be able to practically demonstrate removal performance of a selected adsorbent on specific substrates in a continuous adsorption column with regeneration.
(v) To be able to practically understand the basics of membrane separation using different membrane modules.
