摘　　要：研究了炼油厂加工含硫原油蒸馏装置减压塔硫化亚铁的形成,装置停工检修时硫化亚铁自燃机理及其对装置的危害。介绍了减压蒸馏塔垢样的组成;清洗此种垢样,采用的碱洗方法,清洗机理,化学清洗剂的组成;采用塔器级联循环清洗方案,有效地吸收硫化氢,确保清洗过程安全环保,清洗效果良好,无二次浮锈生成。To research on oil refinery processing high sulfur crude oil distillation tower of ferrous sulfide formation, unit overhaul ferrous sulfide spontaneous combustion mechanism and harm of device. To introduces the vacuum distillation tower scale sample composition, cleaning the scale sample, using safety alkali washing method, cleaning mechanism, chemical cleaning agent composition. The tower to use cascade cycle cleaning solutions, effective absorption of hydrogen sulfide, ensure the cleaning process safety and environmental protection. The cleaning effect is good, no two floating rust.
