引言采用循环水做冷却介质的水冷器,管束循环水侧经常出现腐蚀泄漏的情况,本文研究分析循环水对水冷器的腐蚀泄漏原因,并分析减缓循环水对水冷器腐蚀的对策。炼油部250万吨/年常减压装置是以中东含硫原油为依据而设计的燃料型蒸馏装置。该装置共有水冷器6台,大部分材质为碳钢,所用冷却水为循环水,2013年以来,多台水冷器发生管束泄漏问题,个别水冷器出现泄漏2次的情况,已经影响了设备的安全运行及生产成本增加。这些泄漏主要集中在管程循环水侧,腐
In this paper, the causes of corrosion and leakage of circulating water to water coolers are analyzed and analyzed, and the countermeasures to reduce the corrosion of water coolers by circulating water are analyzed. The 2.5 million tons / year atmospheric and vacuum unit of the Refining Department is a fuel-type distillation unit designed on the basis of Middle East sulfur-containing crude oil. The device has 6 water coolers, most of which are made of carbon steel and the used cooling water is circulating water. Since 2013, multiple water coolers have had pipe bundle leakage problems, and some water coolers have leaked twice, which has affected the equipment’s Safe operation and production costs increase. These leaks are mainly concentrated in the pipe cycle water side rot
