cold box
Thread Content
Which expert is familiar with the internal structure of a cold box, as well as the issues that need to be taken into account when putting it into use and during its routine maintenance?
If you work in manufacturing, there’s no need to look at it; you don’t really need to pay attention to it either
I mainly want to understand its internal structure. I know it is an aluminum plate-fin heat exchanger; by understanding its internal structure, I can figure out what needs to be taken into consideration during operation and use
There are many discussions on the structure of cold boxes and precautions for using plate-fin heat exchangers in the forum. Normally, it’s important to ensure that the materials entering the cold box are clean and free of moisture. The cold box also needs to be maintained at a slight positive pressure.
The cold box is maintained at a slight positive nitrogen pressure of 0.05 MPA
