Effects of fouling and its aging in shell-and-tube heat exchangers
Abstract
The use of mathematical models to predict the fouling rate and deposition aging in heat exchangers assists in monitoring the performance of this equipment and in the development of strategies for mitigating fouling. In this context, the objective of this paper was to evaluate the impact of these phenomena on the shell and tube heat exchanger performance in a refinery, using the modified Ebert-Panchal model and the two layers aging model. For that purpose, the Scilab environment was used for simulations. The results of this paper were close to the results found in the literature.
