Mass Transfer Lab

Introduction
Separation equipments account for a major part of the capital investment in process industry. Fundamental laws governing the design and operation of these equipments are covered in the course “Mass Transfer”. The purpose of this lab is to introduce the undergraduate students with the most important separation equipments in the process industry, and provide a hands-on training of the proper operation of these units. This helps in not only understanding the theoretical fundamentals of the subject but also helps to visualize its real-world applications in the process industry.

List of Equipment

1. Continuous Distillation Column 2. Batch Distillation Column 3. Liquid/Liquid Extraction Unit 4. Gas/Liquid Absorption Column 5. Gaseous Diffusion Apparatus 6. Tray Drier 7. Ion Exchange Apparatus 8. Fluid Bed Drier

Details of Equipment
Continuous Distillation Column
This unit is used to demonstrate the working of a continuous distillation system. The material and energy balances of a distillation system, calculation of number of theoretical trays, tray efficiency, and column profiles are studied on this unit. It also has the facility to perform azeotropic/extractive distillation.

Batch Distillation Column
Very similar to the continuous distillation column in construction (with the exception of reboiler), this unit is used to demonstrate the batch distillation process at constant reflux ratio and at constant product composition. Additionally, the effect of process variables, like reflux ratio, may also be studied.

Liquid/Liquid Extraction Column
This packed column is used for calculation of distribution coefficient in liquid-liquid extraction processes. The first stage of the process is to extract the solute from feed using a solvent. The column is equipped with an additional distillation system in order to complete the second step of

    Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab, we sometimes can observe only the physical part of the experiment, or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However, in order to understand and achieve more from just simply doing the experiment, we write lab report to more profoundly understand the internal meanings of the experiment we do, and…
