Low Density Polyethylene (LDPE) Plant

Abstract

This book provides a comprehensive introduction to the industrial production of Low Density Polyethylene (LDPE), focusing on the tubular process used in petrochemical plants. Developed by experts in chemical and petrochemical engineering, the content is structured to support both academic learning and practical application in plant operations.

Beginning with the fundamentals of LDPE production, the book explores key stages of the polymerization process, including high-pressure ethylene compression, initiator injection, reaction control, and polymer separation. Special emphasis is placed on the design and function of critical plant systems such as compressors, separators, extruders, and the reactor loop.

The second section examines the utilities and auxiliary systems essential for plant operation, including cooling water systems, steam, instrument air, and safety mechanisms like interlocks and emergency shutdown systems. The final section delves into fluid dynamics, sensor calibration, and the thermophysical behavior of gases and liquids, reinforcing the theoretical foundation required for troubleshooting and system optimization.

Complete with diagrams, control logic explanations, and test questions, this book serves as a practical guide for students, educators, and entry-level engineers in the petrochemical field. It bridges the gap between theory and plant-based experience, making it a valuable resource for understanding LDPE production technology.
