Promoting a revolution in energy production and consumption and building an energy sector that is clean, low carbon, safe, and efficient are the essential conditions for building a beautiful China. The petrochemical industry is not only a large energy pro-ducer but also a large energy consumer, and making innovations in its energy-saving technologies is particularly important. Heat transfer enhancement, as a new energy-saving technology that can significantly improve the process heat transfer performance, has been widely used in chemical industry and other process industries in recent years because it can reduce equipment size, improve thermal efficiency, and reduce energy consumption and waste discharge. It has been widely valued by numerous university researchers, engineers, technicians, and production management personnel. Relevant research results keep mushrooming, including both complete theoretical research and partial practical application. However, no monograph systematically elaborates on the of heat in the industry application and implementation of heat transfer enhancement in chemical industry based on case analysis. In order to comprehensively summarize the practical experience and application achievements of heat transfer enhancement in chemical processes, espe-cially in petrochemical processes, and jointly push the application of heat transfer enhancement technologies to a new level, Professor Lili Sun, national engineering survey enhancement technologies to a new level, Professor Lili Sun, a national engineering survey and design master, took the lead in preparing this monograph.
This monograph analyzes the basic principles of heat transfer enhancement, sorts out the theory and methods of this technology, and briefly discusses the heat transfer the theories and methods of this technology, and briefly discusses the heat transfer enhancement methods for typical energy-consuming equipment. On this basis, the comprehensive practical applicationcomprehensive practical ofofheatheat transfer enhancement in petrochemical enhancement in the petrochemical industry is systematically summarized from three application levels of equipment com-industry is systematically summarized from three application levels of equipment ponents, the processes and the plant as a whole, focusing on the three representative components, processes and plants as a whole, focusing on the three representative sectors the petrochemical industry: oil refining, aromatics, ethylene. first level sectors in petrochemical industry: oil refining, aromatics, and ethylene. The first level is the heat transfer enhancement of equipment components. Heat exchange equipment includes general heat transfer equipment in petrochemical and other fields. Over half a century, it has evolved from the first-generation plain tube shell and tube heat exchanger with only a heat transfer function to the fourth generation with compound heat transfer enhancement technology and microchannel heat transfer enhancement functions. By adopting enhanced heat transfer elements and improving the structure of heat exchange equipment, the fourth-generation heat exchange equipment has achieved the purpose of economical and efficient use of energy. The second level is the heat transfer enhancement of processes. “Pinch point” technology is applied to process flow, and the characteristics of the heat energy during production are analyzed from the perspective of the plant. of the heat energy during production are analyzed from the perspective of plants. The energy bottleneck of the system is identified, and specific measures are taken to achieve process enhancement and energy integration. The third level is the heat transfer enhancement of the plant as a whole. Based on the heat transfer enhancement of equipment components and processes mentioned above, the system energy consumption of the plant is macroscopically constructed and designed from the aspects of plant-wide process flow optimization, integration of process units, matching of utilities and auxiliary facilities, and comprehensive utilization of low-temperature waste heat, so as to build high-quality energy basis for the plant.
This book is the crystallization of more than 40 national and provincial Science and Technology Progress Awards, National Excellent Engineering Design Awards, National EPC Awards, and other achievements of the Sinopec Engineering Incorporation (SEI), including the Development and Application of Efficient and Eco-Friendly PX Suite Technology, which won the grand prize of the National Science and Technology Progress Award, and the Development and Industrial Application of VRFCC Suite Technology, which won the first prize of the National Science and Technology Progress Award. This book is the first monograph in China that comprehensively, systematically, specifically, and graphically discusses the theory, application methods, and effects of heat transfer enhancement in chemical processes. It is hoped that this book will provide strong guidance and reference value for engineers, researchers, and production management personnel in related fields as well as for teachers and students in colleges and universities.
This book is rewritten from Heat Transfer Enhancement in Chemical Process in Chinese, compiled by Lili Sun. Lili Sun was responsible for designing the structure of the book, drawing up an outline, setting the writing requirements, and coordinating and finalizing the manuscript. Lili Sun, Defei Wu, Liping Gao, Jiangning Ying, Zhiqiang Wei, and Yabiao Wang revised, translated and proofread the book, and Xiaohua Jiang, Zhao Yang, Bo Cao, Yiru Li, Jiayi Zhu, Wenxin Zhang, Liwei Cao, and Jianguang Cai participated in the translation.
Except for Professor Bofeng Bai from the National Key Laboratory of Multiphase Flow in Power Engineering at Xi’an Jiaotong University, the authors of the book in Chinese are all from SEI. With a high theoretical level and rich practical experience, they have made great efforts for the manuscript, showing a rigorous and meticulous attitude and professionalism. We owe them many thanks.
This book strives to achieve the integration of theory with practice, the integration of process technologies with process enhancement technologies, the integration of process units with utilities, and the integration of local with overall plant, so as to ensure that it is academic, systematic, original, novel, and practical. However, due to the limitation of our knowledge, there may be inadequacies in this book. Corrections from readers are more than welcome and greatly appreciated.
