Hello All,
I have a query regarding rating of existing exchanger.
I have an existing exchanger for which geometry is available, however, I do not have the process data for that exchanger.
I have a new process service and I need to check if the above mentioned existing exchanger can be used for the same. For the new process service, I have the process data, U value, etc.
Do I really need the process data for which the existing exchanger was originally designed or the exchanger area calculated from the geometry available with me should suffice the requirement.
My understanding is to calculate the required area for the new service & if it is lower than the area of the existing exchanger, then it should suffice my requirement.
Needless to mention, I will check the suitability of the existing exchanger for the new process service for following:
1. TEMA type
2. Material of Construction
3. Pressure drop etc.
Can someone please confirm the above understanding.
Thanks
