Chemical engineering thermodynamics is the theoretical basis of chemical process research， development and design， and is also a required course for chemical majors in colleges and universities. The concept of chemical engineering thermodynamics is rigorous and theoretical， which often makes many students confused by the derivation of complex and lengthy mathematical formulas and abstract concepts. In order to meet the needs of the reform in teaching of chemical engineering thermodynamics. Based on many years of teaching experience， the editor continues to reform and innovate teaching contents and methods. By introducing practical cases to enhance the charm of the course， introducing relevant international cutting-edge research content to broaden students’ horizons， and strengthening the connection between disciplines in combination with experimental phenomena and other core courses of chemical engineering， and the teaching effect of chemical thermodynamics is improved. Focusing on the transformation and effective utilization of material and energy， the narrative strives to go from shallow to deep. Combined with well-designed examples and exercises， it emphasizes the connection between the basic principles of thermodynamics and practical applications. It organically infiltrates the elements of ideological and political education， and cultivates students’ thermodynamic knowledge system and basic literacy. It incorporates actual cases of thermodynamic knowledge in chemical production and uses chemical process simulation software to stimulate students’ interest in learning and innovative spirit.
The book consists of eight chapters， the first chapter mainly introduces the chemical engineering thermodynamics， research content and some basic concepts of chemical engineering thermodynamics. The second chapter introduces the p-V-T relation and thermodynamic equation of state of pure fluid， introduces a practical case involving thermodynamics knowledge， explains it by using the principle of chemical thermodynamics， stimulates students’ interest in chemical thermodynamics， and enables students to understand the importance of chemical thermodynamics through practical cases. The third chapter and fourth chapter describe the thermodynamic properties and calculation of fluids， and introduce how to express physical quantities that cannot be directly measured by Maxwell relations and residual properties. Emphasis is placed on the understanding of basic concepts of multicomponent thermodynamics such as partial molar properties， mixing variables， ideal solutions and excess properties， which guide students to deal with complex mathematical formulas， and make the thermodynamics knowledge of rigorous theory and abstract concept easy to understand. In the fifth chapter， the properties and criteria of phase equilibrium， the mutual calculation of T， p， x and y， and the phase equilibrium and expression of mixtures are introduced. By introducing concepts such as ideal work， lost work and exergy， the sixth chapter explains that energy has both “quantity” and “quality”， so as to understand the maximum utilization limit of energy in the chemical process， cultivate students’ awareness of effective use of energy and the concept of correct and rational use of energy. The seventh chapter is the introduction of the thermodynamic cycle. Through the study of this chapter， students’ consciousness of energy conservation and emission reduction can be cultivated. Chapter eight discusses chemical equilibrium， the calculation of equilibrium constant， the influence of temperature and pressure on equilibrium conversion and the equilibrium of chemical reactions in complex systems. By introducing the knowledge of chemical reaction equilibrium into the example， the general chemical equilibrium law is obtained through rigorous formula derivation.
Due to the limitation of the editor’s level， the deficiencies in the book are unavoidable， and we sincerely hope readers can give criticism and correction for further modification.
