大型工业装置的化学清洗系统特点及对策

The characteristics and countermeasure of chemical cleaning systemin large-scale industry unit

成功的化学清洗工程，一方面应选择有效的清洗方法、清洗药剂和工艺条件，另一方面还应设计完善的清洗泵站和系统处置方案，两者同等重要．因此，就大型工业装置化学清洗的分类，化学清洗泵站的设计要求，成套装置的化学清洗系统特点等进行了详尽地阐述．

The effective cleaning method, cleaning agent and technological condition should be chosen in a successful chemical cleaning process, on the other hand, the cleaning pump station and temporary system should be designed reasonably. Both of them are important. Therefore, the classification of chemical cleaning system in large-scale industry unit, the designing requirement of pump station in chemical cleaning process, the characteristics and countermeasure of chemical cleaning system are expounded respectively.
