Hello everyone,
I'm designing a new hot oil loop and I got confused about the trim cooler. Should it be designed for the highest consumer duty or should it be as per the fired heater turndown duty ?
The duty percentage for each consumer are as follow:
-Heat exchanger 1 represents 74% of the total duty.
-Heat exchanger 2 represents 10% of the total duty.
-Heat exchanger 3 represents 12% of the total duty.
-Heat exchanger 4 represents 4% of the total duty.
The exchangers 1 and 2 doesn't work all the time, one can be working and the second not working or both not working.
The exchangers 3 and 4 work always at the same time.
The lowest duty will be the duty of exchanger 2. So I've got confused how should I design my trim cooler as per the highest duty, the lowest duty or the fired heater turndown ?
Your advice and guidance are much appreciated
