For all other bteup syllabus 4th sem chemical eng 2019-2020 you can visit BTEUP Syllabus 4th Sem Chemical Eng 2019-2020 Subjects. The detail syllabus for mass transfer operations i is as follows.
Rationale:
In this subject the basic concepts of mass transfer are covered to enable the students to understand working of various mass transfer equipment like distillation column, gas absorption columns, dryers, cooling towers and extraction columns etc. which are used in industries for purification of products
Learning Outcomes:
After completion of this course, the students will be able to:
- Understand the fundamentals of mass transfer operations
- Estimate the diffusivity for molecular diffusion in gases and liquids.
- Find out local and overall mass transfer coefficient for interphase mass transfer.
- Understand various mass transfer processes like diffusion, adsorption, stripping, humidification and drying.
1. Introduction to Mass Transfer Operations and Classification (02 periods)
For complete syllabus and results, class timetable and more pls download iStudy Syllabus App. It’s a lightweight, easy to use, no images, no pdfs platform to make students life easier.
2. Diffusion (20 periods)
Definition of diffusion and its classification viz diffusion under concentration, pressure and thermal gradient, forced diffusion and eddy diffusion.
Role of diffusion in mass transfer, Fick’s law, diffusion in the gas phase equimolecular counter diffusion, diffusion through stationary gas. Mass transfer coefficient, film theory and penetration theory, surface renewal theory of mass transfer, diffusion in solids, interface mass transfer, relation between film and overall mass transfer coefficient, Knudsen diffusion.
Simple numerical problems based on Fick’s law
3. Gas Absorption and Desorption (20 periods)
Condition of equilibrium between gas and liquid, mechanism of absorption, material balance and design equation of operating line. Absorption factor, concept of transfer unit (HTU and NTU) height of column based on condition-gas film, based on condition-liquid film, height of column based on overall coefficient, HETP for packed column of distillation, types of tower packing, properties of tower packing, problems encountered like flooding, channeling, and weeping, loading, choice of solvent, Raoult’s law and Henry’s law.
4. Humidification and Dehumidification (14 periods)
For complete syllabus and results, class timetable and more pls download iStudy Syllabus App. It’s a lightweight, easy to use, no images, no pdfs platform to make students life easier.
5. Drying (14 periods)
General Definition – moisture content (wet and dry basis), equilibrium moisture content, bound moisture content, unbound moisture content, free and critical moisture content, rate of drying curve, time of drying, constant and falling rate periods,drying equipment – tray dryer, rotary dryer, spray dryer, fluidized bed dryer and application.
Instructional Strategy:
Field visit will make the students familiar with different types of column (packed/tray) and different types of packings/trays used in the column. This will also make the students aware of auxiliary equipment/models/supports used for the columns. Along with the theoretical part, emphasis should be given to problem solving and practices especially for distillation column, absorption and humidification.
