Preface

The production process of chemical products is a process in which raw and auxiliary materials are transformed into products that meet people’s needs through a series of physical and chemical changes. In addition to the non production factors such as market, management and sales, the economic benefits of chemical products production largely depend on whether the production methods and processes adopted are advanced, reasonable and optimized, which are embodied in the design of production equipment and technology. Therefore, the design of production process of chemical products is the basis for the production of chemical products and obtaining good economic benefits. Production process design is the core of chemical product production process design, and it is also the first design content. It can not only outline the whole design and determine the direction of the whole design, but also play a leading role in organizing and coordinating the cooperation of various non technological specialties. When the process design principle is determined, the principles of civil engineering, equipment, instrument and public works are determined with the process. Therefore, the design of production process has an important impact on the level and quality of the whole design, as well as whether the project can be put into operation successfully and achieve good economic benefits. Reasonable and optimized production process is the basis and guarantee to produce qualified chemical products and obtain good economic benefits. Therefore, in the design of chemical project, we must first pay attention to the design of production process.

   In view of the importance of the production process design in the whole chemical project design, this book attempts to make a more comprehensive and systematic introduction to the problems involved in the production process design, pays attention to the systematicness and integrity of the content description, and strengthens the scientificity, integrity, seriousness and standardization of the process design. This book gives readers a complete and clear understanding of the process and method of chemical product production process design, which is conducive to cultivating readers’ overall concept of engineering design, process optimization concept, production practice concept and technical and economic concept.

前 言

化工产品的生产过程就是原辅材料经过一系列的物理的、化学的变化转变成满足人们需要的产品的过程。化工产品生产的经济效益除与市场、管理和销售等非生产因素有关外，在很大程度上取决于所采用的生产方法和工艺是否先进、合理和优化,具体体现在设计的生.产装置和工艺上， 因此， 化工产品生产工艺的设计是化工产品的生产及其取得良好经济效益的基础。生产工艺流程设计是化工产品生产工艺设计的核心，也是需要最先进行的一项设计内容。它不但能勾画出整个设计的概貌，决定整个设计的方向， 而且还起着组织与协调各个非工艺专业互相配合的主导作用。当工艺设计原则确定后，土建、设备、仪表及公用工程等各项原则均随着工艺的确定而确定下来。因此，生产工艺流程设计对整个设计的水平和质量.以及项目投产能否取得成功并取得良好经济效益具有重要影响，在整个化工设计中居于核心和支配地位。合理、优化的生产工艺流程是生产合格化工产品并取得良好经济效益的基础和保证，因此,进行化工项目的设计，必须首先重视生产工艺流程的设计。
      鉴于生产工艺流程设计在整个化工项目设计中的重要性,本书尝试对生产工艺流程设计所涉及的问题做较全面系统地介绍,注重内容阐述的系统性和完整性， 强化了工艺流程设计的科学性、完整性、严肃性和规范性,给读者对化工产品生产工艺流程设计的过程与方法以完整、 清晰的认识和了解,利于培养读者从事工程设计的全局观念、过程优化观念、生产实际观念和技术经济观念。
