Aspen Plus: Chemical Engineering Applications, 2nd Edition is a textbook designed for chemical engineering students, instructors, and industry professionals. Written by Kamal I. M. Al-Malah, this volume demonstrates how to implement Aspen Plus V12.1 to solve operational challenges across chemical process industries.

The technical content establishes a clear sequence through essential unit operations and physical property modeling. Early chapters cover flowsheet features, flash separation, and distillation columns, followed by liquid-liquid extraction and heat exchanger design. Subsequent chapters explore reactors with simple and complex kinetic forms, electrolyte chemistry, polymerization, solids handling, safety measures, and energy saving approaches.

To build practical simulation skills, the text provides step-by-step examples, analytical explanations, and direct screenshots of Aspen Plus software interfaces. End-of-chapter problems and long-term project problems offer students structured practice in applying these software tools to process engineering calculations.
