一、引言有时两个化工厂生产同样的产品、采用同样的工艺,但生产线或设备会出现不同的腐蚀情况。本文通过实际事例来说明和评述工艺过程和环境中的某些可变因素,是如何影响设备腐蚀的,使化工厂的管理人员和工程技术人员明白,在化学工业中会碰到哪些隐蔽的危险因素。在设计化工厂时,设计人员会认真地注意到流速、管道、泵和工艺设备的尺寸,以 I. INTRODUCTION Sometimes two chemical plants produce the same product using the same process, but different corrosion situations occur in the production line or equipment. This paper illustrates and comments on some of the variables in the process and environment through practical examples, which affect the corrosion of the equipment and make chemical plant managers and engineers aware of hidden dangers in the chemical industry factor. When designing a chemical plant, the designer takes careful note of the size of the flow rate, piping, pumps, and process equipment to
