加工进口劣质原油,为企业带来可观的经济效益,但随着原油腐蚀性的增强,给装置带来了明显腐蚀危害。同时对下游设备也产生极大的影响,出现了新的腐蚀问题,其应对措施及理念也要更新,如果不加以重视,将危及安全生产。1柴油罐的腐蚀现状柴油罐以往腐蚀性较小,通常表现在罐底板存有水等腐蚀介质而产生的底板腐蚀,因此防范措施只对罐内底板及第一圈板进行防腐处理。但近两年加工高 Processing of imported crude oil, for the enterprise to bring considerable economic benefits, but with the corrosive enhancement of crude oil, the device has brought significant corrosion damage. At the same time, it also has a great impact on the downstream equipment. A new corrosion problem has emerged. Measures and concepts to deal with them have also to be updated. If not taken seriously, safety production will be endangered. 1 Diesel tank corrosion status Diesel tank in the past less corrosive, usually in the tank floor with corrosive media such as water and corrosion caused by the floor, so the precautionary measures only on the tank bottom plate and the first ring of preservative treatment. But in recent years processing high
