Abstract
The performance of heat integration systems
is quantified in terms of the amount of heat that
is recovered. This decreases with time due to
increased fouling of the heat exchange surface.
Using the "Total Fouling Related Expenses (TFRE)"
approach, economic incentives for heat exchanger
cleaning are evaluated using linear, exponential,
and exponential finite decrease models of the
heat recovery decay. A mathematical comparison
of mechanical and chemical cleaning of heat
exchangers has identified the most significant
parameters which affect the choice between the
two methods.
