Mass Transfer Operations: Diffusion and Interphase Transfer

Understanding how substances move and mix at the molecular level is fundamental to chemical engineering and separation processes. This text-based course guides you through the foundational physics and mathematics of mass transfer operations without unnecessary complexity. You will transition from basic physical concepts to solving complex transport equations, giving you the analytical skills needed for academic exams, professional licensing, and practical engineering design. What you'll learn: - Understand the fundamental laws of molecular diffusion, including Fick's laws. - Calculate mass transfer coefficients under various flow conditions and geometries. - Analyze interphase mass transfer using two-film theory and penetration models. - Solve steady-state and unsteady-state diffusion problems with step-by-step mathematical techniques. - Apply mass transfer theories to modern engineering applications like membrane separations and environmental filtration. The course starts with essential terminology and governing equations before moving into practical mathematical modeling and interphase transport. You will practice through detailed written derivations, worked engineering examples, and self-assessment exercises. This course is designed for engineering students, exam candidates, and professionals looking to refresh their transport phenomena knowledge. No prior advanced transport experience is required, though a basic understanding of calculus and chemistry is helpful. Start reading today to master the core principles of mass transfer operations.
