炼制含硫较高、含盐较多的原油的设备,一般都腐蚀得比较严重,给生产带来了巨大的损失。为了防止腐蚀,延长生产周期,多年来,广大工人、技术人员从工艺防腐、合理选用耐蚀钢材以及改进设备结构等方面进行了大量试验研究工作,并且总结出了一些较好的综合性的防腐措施,显著地降低了腐蚀速度,延长了生产周期。
The equipment for refining crude oil with high sulfur content and high salinity generally corrodes more severely and brings huge losses to the production. In order to prevent corrosion and prolong the production cycle, over the years, a large number of experimental and research work have been carried out by workers and technicians in terms of process preservation, rational selection of corrosion-resistant steel, and improvement of equipment structure, etc., and some good comprehensive anticorrosion products have been summarized Measures, significantly reducing the corrosion rate, extending the production cycle.
