Mass Transfer: Fundamentals and Applications by Hines and Maddox

Mass Transfer: Fundamentals and Applications by Hines and Maddox

Mass transfer is the study of how molecules or particles move from one phase or location to another. It is an important topic in chemical engineering, as it affects many processes such as separation, reaction, and transport. Mass transfer can be coupled with other phenomena such as heat transfer, fluid mechanics, and thermodynamics.

One of the classic textbooks on mass transfer is Mass Transfer: Fundamentals and Applications by Anthony L. Hines and Robert N. Maddox. This book was published in 1985 by Prentice Hall PTR and covers the basic principles and applications of mass transfer in a clear and comprehensive way. The book consists of 11 chapters that cover topics such as:

  • Concentration and flux relationships

  • Coupled processes

  • Diffusion coefficients

  • Mass transfer coefficients

  • Interphase mass transfer

  • Mass transfer with chemical reaction

  • Distillation

  • Absorption

  • Extraction

  • Leaching

  • Drying

The book also includes numerous examples, problems, and illustrations to help students understand and apply the concepts of mass transfer. The book is suitable for undergraduate and graduate courses in chemical engineering, as well as for practicing engineers who want to refresh their knowledge of mass transfer.

Mass transfer is a complex and diverse subject that has many applications in various industries and fields. Some of the common examples of mass transfer processes are:

  • Distillation: The separation of a liquid mixture into its components based on their different boiling points. Distillation is widely used in the production of fuels, chemicals, beverages, and pharmaceuticals.

  • Absorption: The removal of a gas or vapor from a mixture by contacting it with a liquid that can dissolve it. Absorption is often used to purify gases, recover solvents, or capture pollutants.

  • Extraction: The transfer of a solute from one liquid phase to another that is immiscible or partially miscible with the first. Extraction is commonly used to separate organic compounds, metals, or drugs from aqueous solutions.

  • Leaching: The dissolution of a solid by a liquid that flows through it. Leaching is frequently used to extract valuable minerals or metals from ores or wastes.

  • Drying: The removal of moisture from a solid by evaporation. Drying is essential for preserving food, wood, paper, and other materials.

To analyze and design mass transfer processes, engineers need to understand the fundamental concepts and equations that govern mass transfer. Some of the key concepts are:

  • Concentration: The amount of a substance per unit volume or mass of a phase. Concentration can be expressed in various units such as mole fraction, mass fraction, molarity, molality, etc.

  • Flux: The rate of mass transfer per unit area across an interface or within a phase. Flux can be driven by concentration gradients, pressure gradients, temperature gradients, electric fields, etc.

  • Diffusion: The spontaneous movement of molecules or particles from regions of high concentration to regions of low concentration due to their random thermal motion. Diffusion can occur in gases, liquids, or solids.

  • Mass transfer coefficient: A proportionality constant that relates the flux to the driving force for mass transfer. Mass transfer coefficients depend on the properties of the phases, the geometry of the system, and the mode of operation.

  • Interphase mass transfer: The transfer of mass across an interface between two phases. Interphase mass transfer can be influenced by factors such as interfacial area, turbulence, film resistance, chemical reaction, etc.
