Textbook in PDF format This textbook covers the elements of unit operations (distillation, extraction, heat exchangers, evaporators, absorption columns, humidification processes) along with related momentum, energy, and mass transport phenomena, as well as chemical reactors (ideal and non-ideal, including extensions to non-isothermal conditions and reaction networks). The book’s focus is on fundamental principles – it is designed for readers approaching this subject for the first time, presenting topics in a way that is simple enough to grasp yet rigorous enough to provide the tools needed for detailed analysis later. Theoretical concepts are interspersed with worked exercises, sufficient to bridge theory with practical case studies.
