| 摘 要： | 阐明了润滑油精制装置中的糠醛腐蚀及生焦机理。根据工艺流程的特点，采用注入有机胺类缓蚀剂等措施，可破坏糠醛、糠酸和水的共沸，阻止糠酸从糠醛回收塔返回装置系统，结果使全装置酸值下降，同时使全装置的腐蚀及焦生成量减少，装置开工周期从一年延长至两年半。

| Abstract: | As corrosion and coking mechanism is caused by furfural in lube oil refining facilities,it is worthwhile to introduce organic amine as inhibitor in the technological process,to destroy azeotropic mixture of furfural,furoic acid and water,and hence prevent the returning of furoic acid from recovery tower into facility system.As a result,the acid value in the whole facilities is decreased and the corrosion and coking are also reduced. |

| Keywords: | lube oil furfural furoic acid coking corrosion inhibitor |
