摘要
介绍高压加氢装置设备腐蚀类型及取得良好效果的防腐措施,对中国石化海南炼油化工有限公司渣油加氢和加氢裂化两套高压加氢装置自开工以来影响长周期运行的主要设备腐蚀问题进行梳理和分析,并针对性地采取相应措施,提出操作和后续改进建议。几年来的生产运行结果表明:在设计计算、选材和制造方面打好基础,在工艺操作和设备检验、防腐等方面加强管理,能够达到高压加氢装置安全、稳定、长周期运行的目的。
The corrosion types of high pressure hydrogenation equipment and related effective pro- tecting measures are introduced. Main equipment corrosion issues happened during the operation of two sets of high pressure hydrogenation units (residue hydrotreating and hydrocracking) in Hainan Petro- chemical Company since startup, as well as the countermeasures are summarized, and some suggestions for operation and further improvement are proposed. From the years of production experiences, it can be seen that based on a proper design, optimum material selection and equipment manufacture, during the daily work, strengthening managements of process operation, equipment inspection and corrosion pro- tection, a long-term safety and stable running of high pressure hydrogenation unit is truly possible.
