摘要
某大型烷基化/废酸再生(SAR)联合装置在运行期间,多个系统出现比较严重腐蚀泄漏现象,影响装置安全平稳生产。通过分析各部位腐蚀情况,研究各类腐蚀形成机理,有针对性提出解决方案。通过优化工艺条件、设备设施改造等多种手段,有效减少了联合装置腐蚀情况的发生。
Abstract
During the operation of one large-scale alkylation/spent acid regeneration (SAR) complex, heavy corrosion & leakages have been found in many systems, having serious impact on safe & stable production.Through analyzing corrosion status at each position and researching corrosion formation mechanism, some anti-corrosion solutions are proposed specifically against corresponding problems.By taking various measures such as process optimization, equipment renovation, etc., the corrosion is effectively reduced through the entire complex.
