For petrochemical finned air coolers, how can dirt accumulated on the fins be removed?
Thread Content
The following refers to the tower top air cooler in petrochemical hydrogenation production units; after being in use for a period of time, a considerable amount of dirt accumulates on the surface of its fins, which affects the cooling efficiency of the air cooler. How can such dirt be removed?
This is difficult to remove; such a usage environment is not suitable for this type of finned tube. Once it has been used, it is recommended to install a screening filter
Can it be tried with a dry ice cleaner?
Based on the chemical properties of the dirt, appropriate cleaning solutions are used for chemical cleaning, such as acid cleaning, etc. For reference.
