Mass Transfer
This course focuses on the principles of mass transfer and its applications in separation processes. Students will learn about diffusion, mass transfer coefficients, and mass transfer operations such as distillation, absorption, and filtration. By the end of the course, students will be able to analyze and design mass transfer processes for chemical production.
