Shell-and-Tube Heat Exchanger Geometry Modification: An Efficient Way to Mitigate Fouling

Application of an Artificial Neural Network Method for the Prediction of the Tube-Side Fouling Resistance in a Shell-And-Tube Heat Exchanger

“…Among several industries that are the most concerned by the fouling problem is the chemistry industries [1]. The geometry of the heat transfer surface, the operation conditions of the fluid and the heat exchanger are some variables that can have a huge effect on the fouling [3,4]. To establish an empirical or semi-empirical correlation to accurately predict exactly the fouling resistance is hard by considering all measurable variables of the system.…”

Design of shell and tube heat exchangers considering the interaction of fouling and hydraulics

“…Additionally, the modification of the structure of the heat transfer surface can also mitigate the fouling problem. 19 The usual approach to address fouling in the design using fixed fouling factors has important limitations, 20 ignoring the influence of the heat exchanger design on the fouling extent. To answer this challenge, several articles have investigated the interconnection between fouling modeling and heat exchanger design procedures for the case of crude preheat trains.…”

“…For example, Wilson et al 17,18 presented overviews of fouling rate models for crude oil streams based on the threshold concept. Additionally, the modification of the structure of the heat transfer surface can also mitigate the fouling problem 19 …”
