Foundations of Mass Transfer Operations

Chemical engineering relies heavily on separating and mixing substances efficiently. Understanding how molecules move and transfer between phases is the key to designing successful industrial separation processes. This text-based course guides you from the fundamental physics of molecular diffusion to the practical design principles of gas absorption and distillation. You will gain the analytical skills needed to model, evaluate, and optimize mass transfer systems in modern industrial settings. What you'll learn: - Understand the fundamental laws of molecular diffusion in gases, liquids, and solids - Calculate mass transfer coefficients and apply boundary layer theories to process design - Analyze phase equilibrium data for gas-liquid and vapor-liquid systems - Design gas absorption columns using operating lines and transfer unit concepts - Evaluate fractional distillation processes using classical graphical and algebraic methods - Apply modern concepts of environmental mass transfer, including carbon capture and sustainable separation processes The course begins with foundational definitions and governing equations of diffusion before moving to convective mass transfer, interphase transport, and the design of stage-wise separation equipment. It is designed for students of chemical engineering, process engineers, and technical professionals seeking a clear, beginner-friendly introduction to mass transfer with no advanced prior knowledge required.
