摘要
根据芳烃装置生产工艺及设备特点，简述了杂质污垢的存在对生产过程的影响以及进行化学清洗的意义介绍了抽提装置的清洗范围、清洗系统划分和清洗工艺过程通过实施化学清洗。
According to the characteristic of the technological process and the equipments of aromatic extraction plants ,the importance of chemical cleaning was reviewed,and the harm to the technological process caused by scale was aslo offered. Based on these,the cleaning scope,the division of the cleaning system and the cleaning procedure was introduced in detail .The result showed that the cleaning quality fit not only the national standard but aslo the special standard of UOP Grop.(from U.S.A).
