Abstract
With the continuous growth of global energy demand and the increasingly severe environmental problems, thermal integration and energy recovery technology in the chemical industry has become an important means to improve energy efficiency, reduce production costs and reduce environmental pollution. The purpose of this paper is to discuss the application of heat integration and energy recovery technology in chemical process and its dual benefits to environment and economy. First of all, in the introduction part, this paper introduces the background, significance and research status at home and abroad, and clarifies the purpose and importance of the research. Then, the second chapter elaborates the basis of energy analysis of chemical process, including energy conservation and transformation principle, energy flow analysis in chemical process, theoretical basis of energy recovery and economic analysis, which lays a solid theoretical foundation for further research in subsequent chapters. In chapter 3, thermal integration technology is summarized, including the concept of thermal integration technology, application in chemical process, design principles and implementation strategies. Chapter 4 discusses the energy recovery technology in detail, including technology classification, system design, case analysis and development trend, and shows the application potential of energy recovery technology in practical chemical production. In chapter 5, thermal integration and energy recovery strategies in chemical processes are discussed in depth, and through process integration optimization methods, implementation of thermal integration strategies, implementation of energy recovery strategies and case studies, how to improve energy utilization efficiency through integrated optimization is demonstrated. Chapter 6 analyzes the environmental benefits of heat integration and energy recovery technologies, the role of the chemical industry in sustainable development, and related environmental regulations and policies from the perspective of environmental impact and sustainable development. The implementation of these strategies can not only improve the energy efficiency of the chemical process, but also reduce environmental pollution and promote the green transformation of the chemical industry.
