针对中国石化天津分公司3号常减压蒸馏装置常压塔塔顶循环管线结垢的问题，详细分析了垢物组成，并从结垢机理和塔顶各物料的性质方面分析了造成常压塔塔顶循环管线结垢的原因。通过减少缓蚀剂注入量、减少有机胺注入量、调整常压塔塔顶注水方案、添加阻垢分散剂等措施，常压塔塔顶循环量达到设计值，且对下游产品未造成影响，解决了常减压蒸馏装置常压塔塔顶循环管线结垢问题。

To study the fouling causes of atmospheric column in Tianjin Petrochemical Company, the composition of the scaling and the properties of materials at the top of atmospheric column were ana-lyzed. Based on the analysis results,technical measures were suggested,such as changing amount of corrosion inhibitor and regulating solution of injection water,adopting the new process and scale disper-sant,resulting in improved fouling situation of the atmospheric column and no harmful effect is occured in down-stream products.
