摘要
介绍了Lan257c尿素专用清洗剂在二氧化碳汽提塔的实际应用过程。在特定的温度、压力和pH值下,清除污垢。验证了污垢的来源是腐蚀介质对合成塔腐蚀后形成的。区别于常规化学清洗,二氧化碳汽提塔的清洗是在封闭循环回路中进行的。
The practical application of Lan257c special cleaning for urea in CO2 stripper wasemphatically introduced.The scale could be removed under the condition of particular temperatures,pressure,and pH values. It was verified that the scale depositing in the synthetic tower was caused bycorrsion medium. The cleaning of CO2 strippers was performed in closed circulation loop,that wasdifferent from common chemical cleaning.
