Membrane Technology for Air Cleaning: Fabrication, Characterization and Application

This book highlights a comprehensive and systematic introduction to the science and technology of gas cleaning membranes. Starting from basic concepts and principles, the book covers the preparation methods, performance parameters, and advances in applications of different types of membrane materials. Industrial smoke and dust emissions are one of the main causes of atmospheric haze. How to strictly control the emission of ultrafine dust and achieve efficient and clean utilization of resources is a common problem faced by industries related to chemical engineering, energy, steel, metallurgy, and building materials. There is an urgent need for new separation technologies. The low efficiency of traditional dust removal technologies cannot meet increasingly strict emission requirements. Membrane technologies provide an effective approach for PM2.5 control with its high separation efficiency and low energy consumption. Especially for the purification of high-temperature gases, it can maximize the utilization of the physical sensible heat of the gas and achieve energy recovery. This book first introduces relevant concepts and terms, separation principles, structure characterization, and evaluation methods of gas cleaning membranes. According to the characteristics of application environments, the preparation methods, performance parameters and application progress of different types of membrane materials, including those for medium and low temperature gases, high temperature gases as well as multi-functional membranes, are described in detail. Relevant equipment and typical application cases in indoor air purification, medical, and industrial fields are discussed. The book also summarizes latest theoretical research frontiers and projects future development trends in this field. This book can be used as a valuable reference for undergraduate and graduate students in materials science, chemical engineering, environmental engineering and researchers engaged in the development of air filtration materials and gas purification technology.  The English translation of this book, originally in Chinese, was facilitated by artificial intelligence. The content was later revised by the author for accuracy.
