Hello,
I am having a case at my industry where we are trying to evaluate a series of crude heat exchanger in such a way that we want to set a plan to clean heat exchangers not based on the fouling factor.
This is due to the consumption of FG that will be increased once the exchanger duty start to reduce.
For example, for Exchanger B in the attached diagram, once its duty starts to reduce, more FG has to be consumed in order to sustain the heater outlet T. I want to look to it in a way that we start the cleaning of the exchanger once the extra FG consumed OPEX is equal to the cleaning cost (assuming $20K).
I am not sure if this is a practice in the industry. Otherwise, please let me know about better approaches.
