| Abstract: | Shaanxi Yanchang petroleum （group） Co., Ltd operates a 1. OMMTAFCC unit to process atmospheric residue. It was found that there has serious corrosion in Due to corrosion of process pipelines and coo dies ling el system of fractionating tower during the normal operation. equipments, there has several leaks and will influence the safe and stable operation of the unit. Based on the corrosion situation of this unit, the main reason of corrosion was analyzed, preliminary discussion the mechanism of corrosion. According to the practical experience in the process of production, several feasible prevention measures were put forward. |
