我国炼油装置采用“一脱四注”防腐蚀技术已有多年,它对炼油设备的防护起了极为重要的作用,但是各厂在具体实施时尚存在很多问题,效果也不尽相同,随着我国新油田的开发含硫原油及高酸值原油的大量增加,腐蚀问题将会更加突出,我国炼油生产过程所用的冷却水装置原设计不符合循环水处理的要求,虽然过去在水处理上做了大量工作,但还存在不少问题。调查的目标是要延长装置的开工周期、减少停车检修时间、降低能耗、提高设备效率、以将防腐蚀及循环水处理工作提高 China’s oil refining plant has adopted “one off four injections” anti-corrosion technology for many years, it plays a very important role in the protection of oil refining equipment, but there are many problems in the concrete implementation of the various factories, the effect is not the same, with With the development of new oilfields in our country, the sulfur content crude oil and the high acid value crude oil will increase greatly. The corrosion problem will be more prominent. The original design of the cooling water device used in China’s oil refining production does not meet the requirements of recycled water treatment. Do a lot of work, but there are still many problems. The objective of the survey is to extend the plant’s start-up cycle, reduce downtime, reduce energy consumption and equipment efficiency to improve anti-corrosion and recycle water treatment
