This book provides a comprehensive and structured overview of the fundamental principles and applied practices that define modern chemical engineering. It explains core scientific concepts underpinning chemical processes, including thermodynamics, transport phenomena, and reaction engineering, while linking these foundations to industrial applications. The discussion integrates process design, system optimisation, and analytical modelling, demonstrating how chemical engineers translate scientific knowledge into efficient and safe production systems. Attention is given to reaction pathways, material balance considerations, and performance evaluation within complex processing environments. The book also examines contemporary developments in simulation tools and digital design platforms that support predictive analysis, operational efficiency, and sustainable practice. By combining theoretical depth with practical relevance, it offers a coherent framework for understanding how chemical engineering principles are applied across manufacturing, energy, and materials industries in technologically advanced settings.

It is intended for undergraduate and postgraduate students, practising engineers, and researchers in chemical engineering. The book serves as an academic reference and professional guide, supporting conceptual learning, process analysis, and informed decision making in industrial operations, research environments, and technology-driven chemical production systems worldwide today.
