This book provides a technically detailed and application-oriented examination of absorption and stripping processes within the petrochemical, oil, and gas sectors. It develops a coherent understanding of mass transfer operations, phase interactions, and equilibrium relationships that govern the separation and purification of complex mixtures. The book combines fundamental scientific principles with practical engineering insights, addressing process design, operational efficiency, and optimisation in industrial environments. It further explores the influence of thermodynamic behaviour, reaction-diffusion mechanisms, and solubility characteristics on system performance. Emphasis is placed on the evaluation and improvement of separation techniques, enabling a systematic approach to enhancing process reliability and productivity. The discussion also considers contemporary developments in refining technologies and environmental management, encouraging a balanced perspective on efficiency, safety, and sustainability in modern process engineering.

This book is intended for engineers, researchers, and advanced students seeking to strengthen their expertise in chemical and process engineering. It supports analytical thinking, technical competence, and informed problem-solving in complex industrial applications.
