高含硫净化装置在运行过程中，N-甲基二乙醇胺（MDEA）溶液发泡问题变得尤为突出，该工况容易造成装旨后路气相带液，严重时会引起冲塔。通过观察装置运行参数，判断总结出MDEA发泡的主要依据是吸收塔的压差上升。结合现场实际操作，发现引起MDEA溶液发泡是各种问题多样化的结果，分别给出解决MDEA溶液系统发泡问题的技术方案。通过对联合装置加入阻泡剂、清洗过滤系统机械过滤器、及时更换活性炭过滤器的活性炭、调整重沸器蒸汽入口的温度等，减小了胺液发泡造成的生产波动及胺液的跑损，实现了除去胺液的杂质和减少胺液降解等目标，得出了详尽的实验数据。数据分析表明该方案取得了较好的生产效果，达到了降耗目的。

During operation process of high sulfur purification device, the foaming problem of N-methyl diethanolamine （MDEA） solution becomes more serious; it can easily cause the gas phase to carry over liquid into later pipeline in the device, and even can cause the tower bumping violently under serious condition. Based on review of operational parameters, it is drawn that MDEA foam is mainly caused by differential pressure increase in absorption tower. Combined with site actual operation, the cause of MDEA solution foaming is found to be combination of variety of problems. Technology scheme for MDEA solution system problem of foaming is put forward. By adding anti-foam agent to combined device, cleaning mechanical filter in filtration system, and timely replacing activate carbon in activated carbon filter, adjusting steam inlet temperature of re-boiler, the target of reduction of production fluctuation and amine liquid loss caused by amine foaming, removing impurities in amine liquid, and reduction of amine degradation are achieved, and detailed experimental data are obtained. Data analysis shows that good production result is achieved with the methods.
