Features: Introduction Introduction "Introduction to Chemical Engineering Design" takes the process design of chemical workshops (sections) as the object, systematically and comprehensively explaining the basic procedures, content, and methods of chemical engineering design, striving for practicality, reference value, and guidance. The book is divided into ten chapters. The preface briefly introduces the significance, role, characteristics, and development of chemical engineering design. Chapter 1 introduces the basic procedures and content of chemical engineering design; Chapter 2 introduces the methods and steps for selecting production methods, process flow design, flow diagram drawing, and determining typical automatic control schemes; Chapter 3 introduces the procedures and precautions for material balance, heat balance, equipment calculation, and selection; Chapter 4 introduces the types, principles, and methods of workshop layout design; Chapter 5 provides a more detailed introduction to the relevant knowledge and regulations of chemical pipeline design; Chapter 6 introduces the relationship between process design and non-process design and the conditions provided; Chapter 7 introduces the procedures and content of writing design specifications and budget books; Chapter 8 introduces the application of computers in chemical engineering design from aspects such as property data retrieval, simulation calculation, equipment calculation, and AutoCAD. Chapter 9 introduces three examples of process design, including the process design of a butadiene rubber polymerization workshop, the process design of an acrylonitrile refining tower, and the process design of a synthetic ammonia plant. Additionally, targeted illustrations of commonly used instruments, chemical equipment, chemical pipelines, and fittings are included at the end of the book as needed. Its main features are: introducing the new design standards and regulations currently used in the petrochemical industry in the second, third, fourth, and fifth chapters; and incorporating the content of computer-aided process flow diagram and assembly drawing into the design examples to make them more practical and comprehensive. This book can be used as a textbook for students majoring in chemical process technology in vocational colleges and also as a reference book for chemical production engineers.
