High-pressure hydrogenation heat exchangers tend to scale easily. How is the heat transfer efficiency of such heat exchangers calculated, and what is the formula used for that?

Heat transfer efficiency = Actual heat transfer amount/Theoretical heat transfer amount × 100%; scaling reduces the heat transfer efficiency of the heat exchanger

The formula you provided is for informational purposes only and is not practical for use. “Scaling reduces the heat exchange efficiency of the heat exchanger, which is also reflected in the outlet temperature.
