摘　　要：循环水冷却器结垢是一种常见现象,结合某项目压缩机段间冷却器的结垢问题,说明了结垢对设备和工艺系统的危害。分析得出,壳侧工艺气进口温度高和循环冷却水水质差,是导致换热管内结垢堵塞的主要原因。最后从降低工艺气进口温度、改变冷却介质水质的角度出发,提出了解决方案,保证压缩机段间冷却器的安全稳定运行。Analysis on the scaling problem of inter-stage coolers of compressors in a certain project shows that high inlet temperature of process gas at the shell side and poor quality of circulating cooling water are the main causes of scaling and blocking in heat exchangers.Countermeasures are proposed from the angle of reducing the inlet temperature of process gas and changing the cooling medium to ensure the safe and stable operation of the inter-stage cooler of compressors.

关 键 词：段间冷却器 循环冷却水 结垢
