Preface
With the continuous development of society, the chemical industry also has certain requirements on its mechanical equipment. The production conditions of chemical industrial products are mostly high temperature, high pressure, complex medium conditions and high technical content, and most of their raw materials and products are highly toxic, flammable, explosive and highly corrosive substances. Chemical production plays an important role in the development of the national economy. Therefore, the performance and reliability of the basic equipment for chemical industry production and operation are very high. Without reliable equipment, the chemical industry has no basis for survival. The reliability of equipment operation determines the normal production of chemical industry. The process of modern industrial production is increasingly moving toward the development direction of large-scale, refined and integrated. The overall operation of a chemical plant is actually an extremely complex and large system. Once one of the links fails and the appropriate solution is not taken in time, a major accident will occur in the entire system. Therefore, it is necessary to strictly control the design process of chemical machinery equipment to ensure the normal and safe operation of each link.
This book briefly describes the chemical equipment materials, centrifugal compressors, turboexpanders, valves, general manufacturing technology of process equipment, heat exchangers, tower equipment, cryogenic liquid storage and transportation equipment.
前言
随着社会的不断发展，化工业对其机械设备也有了一定的要求。化工业产品生产条件多为高温、高压、复杂介质条件，高技术含量的，其原料及产品又大多为剧毒、易燃、易爆、强腐蚀性物质，因为化工生产在国民经济发展中占据着重要地位，所以，对于化工业生产运行的基础设备的性能、可靠性就非常高，离开了设备，或者说离开了可靠的设备，化工业就失去了生存的基础，设备运行的可靠与否就决定了化工业生产的正常与否。而现代化工业生产的过程日益趋向大型化、精细化和集成化的发展方向运行，一台运行着的化工设备，整体实际上是一个极其复杂的大系统。而一旦其中的某一个环节发生故障，或者哪一部分使用不当又没有及时采取合适的解决措施，就会导致整个系统发生重大事故，因此，必须要对化工机械设备设计过程进行严格的控制，确保每个环节的正常安全运行。
本书将通过对化工设备材料、离心式压缩机、透平膨胀机、阀门、过程设备通用制造技术、换热器、塔设备、低温液体储运设备等进行了简单的阐述。
